I can't think of a way to enforce this load order on the modules themselves due to the fact that OHCI might not even be needed for EHCI devices on UHCI (Intel) based chipsets :( Can anyone else? The three modules perhaps should be a bundle of whatever ones you have enabled, and internally we can dispatch the initialization to occur in the correct order from a top-level module_init(). If the devices need to be initialized in a certain order in a situation like this, it really seems like it is the kernel's job to enforce it. I agree. Here's some information from Intel about where they have seen this happen for UHCI controllers, so it's not just an OHCI issue :( thanks, greg k-h We had a logic analyzer attached to the bus going to the ESB (ICH) which has the USB controller in it. In the passing case we would see no accesses to UHCI IO registers while EHCI initialized and sets its config flag. The EHCI Port Status Control registers were then read and then we see a write to the EHCI Port Status Control registers port owner bit for the low speed devices (keyboard mouse). This turns control back over to the companion UHCI controller.=20 In our most prevalent failing case (#1 below) we never saw the write to port owner bit on the ports with the low speed devices. In the passing case we see the write to the port owner bit. I do not see how this would have anything to do with flakey hardware especially since we can reproduce this on all of our systems and the same device (USB controller) is used on multiple products.=20 I really believe that this has to do with the UHCI and EHCI drivers running on top of each other. This seems to be happening fairly often on our systems. If the EHCI driver runs first then we do not see the failure. If they are running at the same time then we see different failure symptoms.=20 1) We see that the ports with low speed devices are still in EHCI mode (port owner bit not written to in EHCI driver). In our analyzer captures we see the reads from the Port Status Control register and it is indicating that there are low speed devices on the ports. Can you tell us why the driver would not be doing the write to the port owner bit when it sees that low speed devices are attached to that port? Is there something specific that it looks for and decides not to do the write? 2) In other cases we see that the ports with the low speed devices are back in UHCI mode but the ports are disabled. In this case we see from the analyzer traces that the UHCI driver has completed setting up the port. It has actually enabled that port in UHCI mode. We then see the EHCI driver comes in and it resets everything. The driver then gives control back to the UCHI controller (by setting the port owner bit) but...since the UHCI driver has already setup this port once it seems that it does not go back and set it up again. In this case we do not think that the UHCI driver has completed running when the EHCI driver comes in and does the reset. Can you tell us if the UHCI driver was interrupted in the middle but after the ports with the low speed devices had been enabled would the UHCI driver ever go back and reinitialize the ports with the low speed devices? 3) In some cases we see errors in the DMESG log but it seems to recover. So we really do believe that it has to do with the EHCI driver running in the middle of the UHCI driver running. And then dependent upon when the EHCI driver comes in, while the UHCI driver is running, we see the different failures. And since by default these drivers are not forced to run sequentially we are susceptible to the failure.=20 - This SF.net email is sponsored by: Splunk Inc.

It happens only if I make sure OHCI gets loaded first and then EHCI right afterwards. It seems that indeed it is important for EHCI to get loaded first, and in-kernel this is ensured by the link ordering. However, when both OHCI and EHCI are built as modules (or, similarly I guess, OHCI is built-in and EHCI is modular) there appears to be nothing in userspace which makes sure EHCI gets loaded first. When this triggers, in OHCI's root_port_reset(), the port status register reads 0x111 in that inner-loop and the value never changes. It stays like this forever. I agree with Ben; the best way to solve this is in the kernel. Even if you did manage to make sure that modules were loaded in the right order initially, that wouldn't help if somebody starts unloading and loading modules by hand. The underlying cause of the problem appears to be related to the fact that it is impossible in principle to detect a disconnect while a full/low-speed reset is in progress. However the hardware shouldn't rely on this, and it should fail gracefully when an unexpected disconnect does occur. For example, what would the controller do if the user unplugged the USB cable right in the middle of a reset? Anyway, it certainly would be easy enough to make port resets mutually exclusive with EHCI initialization. That would work on any platform, PCI or not. That's a good idea, any thoughts as to how to do this? I think I can find some Intel and Dell people who would be glad to test this out if you have a proposed patch. thanks, greg k-h - This SF.net email is sponsored by: Splunk Inc.

Is EHCI maybe trying to switch ownership of that port? Is maybe the (newish) autosuspend stuff kicking in? I wouldn't know, the machine hangs and doesn't get any further. To add some more information here, I think the EHCI idea might hold some water. What I have here are two NEC OHCI USB interfaces and one NEC EHCI USB interface on PCI. Aparently they all go through a shared USB hub, mapped like this: HUB Port 1: OHCI #1, EHCI HUB Port 2: OHCI #2, EHCI HUB Port 3: OHCI #1, EHCI HUB Port 4: OHCI #2, EHCI HUB Port 5: OHCI #1, EHCI The OHCI ports go out to external USB connectors on the back panel of the machine, whereas the EHCI is connected up to an internal USB storage CDROM device and what appears to be another USB hub. The problem seems to be very strongly tied to timing. For example simply adding ignore_loglevel to the kernel boot command line can make the problem go away. This got me thinking about your EHCI comment. If these controllers are going through the same HUB, things might go south if OHCI initialized first, then khubd et al. are asynchronously accessing the segments behind OHCI at the same time that the EHCI driver is initializing. Perhaps, this is the kind of sequence of events which makes one of the root ports reset in such a way that the the reset bit never clears. Given that this machine has 64 cpus, the likelyhood for such parallel accesses is very likely :-) Does this make any sense? Yes it does, I'm seeing reports from some hardware companies of the very same thing. If you serialize and load the ehci driver first, and then the ohci driver, that should fix the problem. Does that also work for you? Or are these drivers built into the kernel? thanks, greg k-h - This SF.net email is sponsored by: Splunk Inc. Still grepping through log files to find problems? Stop.

The old /etc/hotplug/usb.rc script made sure to load those modules in the correct order: EHCI first. I expected to find something cute attempting to handle this under /etc/udev, I have failed so far :-) No, nothing cute in udev itself, but it seems that all distros that I know of have a load these modules now type setting in their init scripts that can be used here.

Except that it starts to get messy if each system call is protected with error checking and each piece of data read in as text is tested for validity. Perhaps some or all such carefulness isn't necessary, but it does tend to protect against unforeseen problems. It's much simpler to read it all in at once. Do you really need anything other than the vendor ID, the product ID, and perhaps the bcdDevice value? That's mostly true for device selection. Once we know we have the right device, though, we do use the string index fields to fetch the strings for logging. I know the strings teemselves are in sysfs, but to keep that code portable we read the string desccriptors from the selected device. It was just an idea which would make switching back to a truly passive device descriptor read (like it has been before autosuspend) easy, not only for us but also for other applications. Greg, what do you think? Is it reasonable to add a binary sysfs attribute file containing the device descriptor? (And perhaps also one containing the current configuration descriptor, and the interface descriptors in their individual subdirectories. Maybe even the endpoint descriptors too.) No, we DO NOT PUT DEVICE NODES IN SYSFS! Sorry for yelling, but this comes up every 3-4 months or so for the past 4-5 years and it's getting a bit annoying :) Device nodes go in /dev/ That's what the LSB specifies and to do something else will just wreck havoc with the system (permissions, acls, security, etc.) Even though the binary descriptors are available in usbfs, when a device's usbfs file is opened the device is automatically resumed. This means that a program looking for a particular device will wake up a bunch of unrelated devices. With sysfs there is no such problem. Then use the device information from sysfs to determine which usbfs file to open. Or, help out with the usbfs2 code which uses the device endpoints and should allow you to have a better mapping from sysfs usb device to usbfs2 endpoint and device. thanks, greg k-h - This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.

Every USB device has a piece of top-level static data known as a device descriptor. It's cached by the kernel when the device is connected, and is returned as the first 18 bytes read from a usbfs file descriptor. It's this same data which I'd like to read via sysfs so as to avoid resuming any devices (which is what happens when opening a usbfs file). This device descriptor is, among other things, what one must inspect in order to find the device you're looking for as it contains things like vendour and product identifiers. Yeah, I know a little bit about those things, sorry, was used to calling them configuration due to moving between the PCI and USB specs all the time :) A USB device also has descriptors at lower levels for components such as its interfaces and endpoints. These, too, are static pieces of data. For completeness, although we ourselves don't need sysfs support for them, it'd be logical to provide sysfs files for each of them as well. The USB configuration data? Like you read from the binary usbfs file if you open and read from it? Yes. What you get when you read a usbfs file is the device descriptor followed by all of the interface and endpoint descriptors for the currently selected device configuration. If so, then I have no objection to that, as long as you are taking data directly from the device and not parsing it at all in the kernel and passing it on to userspace.

Look at the PCI file called config in sysfs and see if that is what you are looking for. It's probably the same in concept, but it doesn't contain the actual data. I'm not familiar with how PCI works, but the data in that ifle is probably relevant for describing and/or accessing the device at the PCI level. Perhaps it was in another message wherein you asked if the file could be called configuration rather than descriptor. The problem with this is that the term configuration has a very well-defined meaining with respect to USB devices. The generic USB term for this data really is descriptor, and, especially if this information were to be provided at all levels, that would be the intuitive term to use. Ok, make it called descriptor, that's fine with me.

Re: [Linux-usb-users] can't get USB-serial console to work properly (or is it normal)?
On Wed, Feb 21, 2007 at 10:58:54AM +0100, Tomasz Chmielewski wrote: So far, I've been using a normal serial console with a device running Linux. I configured it in two places: - kernel command line to see kernel messages: console=ttyS0,115200 - /etc/inittab: T0:23:respawn:/sbin/getty -L ttyS0 115200 vt102 (to be able to log in) As to use that serial console I have to open the device, I decided I will use a USB-serial console instead. The changes seemed trivial: - compile all USB/console related stuff in the kernel - kernel command line to see kernel messages: console=ttyUSB0,115200 - /etc/inittab: T0:23:respawn:/sbin/getty -L ttyUSB0 115200 vt102 However, this doesn't work as I expected: 1) I don't see any initial kernel messages on the USB-serial console: Linux version 2.6.20 ([EMAIL PROTECTED]) (gcc version 4.1.1) #56 PREEMPT Tue Feb 20 18:14:38 CET 2007 CPU: XScale-IXP42x Family [690541f1] revision 1 (ARMv5TE), cr=397f Machine: Freecom FSG-3 (...) I guess that's because kernel didn't initialize USB-subsystem yet? 2) After loading the kernel, my system is set up to wait for 10 seconds before continuing and loading the proper init. 10 seconds should be far more than necessary for the system to see all USB devices? Still, when the system loads, I don't see any kernel messages, system loading etc. on ttyUSB0 (I saw these things with console=ttyS0,115200). 3) As soon as the system loads completely, I get a login prompt on ttyUSB0 (started by getty). From this point on, I will get kernel messages onto ttyUSB0. Why do I get kernel messages logged on the USB-serial console that late, only after the system is fully loaded and after I get a login prompt on ttyUSB0? Because that is when the USB serial port is finally found by the kernel. I wouldn't use usb serial devices for console devices to see the kernel logs, due to the lateness of discovery and the need for interrupts to work properly (so it will not show crash dumps.) But for just normal logins, it should work fine. good luck, greg k-h - Take Surveys. Earn Cash.

Re: [Linux-usb-users] Stable API for USB programming
On Wed, Dec 13, 2006 at 03:23:31PM +, Phil Endecott wrote: Dear USB Experts, I am trying to understand the relative merits of the various programming interfaces to the Linux USB system. As far as I can see, the current or planned options include: 1. The kernel device-driver interface (i.e. usb_register()). This looks like a fairly simple interface, documented in the kerneldocs (though something went wrong when I tried to make a PDF) and also at http://www.lrr.in.tum.de/Par/arch/usb/usbdoc/usbdoc.html, which seems accurate despite being seveal years old. Lots of example drivers to learn from in the kernel source. Seems unlikely to change much anytime soon. Being a kernel interface rather than a user-space interface has obvious advantages and disadvantages. The future GPL only issue will matter in some cases. What cases would it matter? 2. The usbfs interface. Described in Documentation/usb/proc_usb.txt, referring to the lightly-commented header file for details of the ioctls. Can anyone point to any more docs or examples? The header file is the best example. It's not a very complex interface. 3. The lots of ioctls design of usbfs seems unpopular with some and searching the lists suggests that there may be other technical problems with the current design, hence a proposed future usbfs2. This will be more like gadgetfs with one inode per endpoint. So is the current usbfs not recommended for new designs? Is waiting for usbfs2 suggested? Is there a useable usbfs2 patch available now? It's being slowly worked on. Right now it is a senior project for a college student, so it might be a while before it shows up in the tree. Or you are more than welcome to help out with the effort to get it moving faster. 3. There are numerous usb files in sysfs. Is there any documentation for any of this, apart from the generic notes in Documentation/kobject.txt and Documentation/filesystems/sysfs.txt? The USB FAQ explains the 1-1.3.1:1.0 style of pathnames, but I don't know what the files in the leaf directories do. Can I read and write them to communicate with the device? No. You can only read the different attributes of the device, and in some cases, change some of the different configuation values of the device. You don't have raw USB data access through sysfs. 4. libusb. Documentation at http://libusb.sourceforge.net/doc. Apparently it is geared towards USB1.1. Doesn't support asynchronous IO. The current v0.1 API will soon be obsoleted by a new v1.0. LGPL license. It works just fine for 2.0 devices too. If you have questions about this, please ask it on the libusb mailing list. Are there other options? I am currently more concerned about the medium/long term stability of the interface and the quality of documentation than the technical features. Why? If you are interested in that, I would suggest the usbfs interface, it's not going away any year soon. (Having said that, the lack of any asynchronous IO in libusb worries me, and I don't think any of the user-space interfaces have a mechanism to get notifications of new devices like the kernel's probe callbacks; presumably I need to cooperate with udev to make this work.) Why, what exactly are you trying to do? Perhaps explaining what you are trying to accomplish would help us out in suggesting what you should use Any advice would be much appreciated. try posting follow-up stuff on the linux-usb-devel mailing list, not the -user list. thanks, greg k-h - Take Surveys.

Also I set CONFIG_USB_SERIAL_EDGEPORT_TI=y.
Also I am compiling io_ti.c and io_ti.h (I don't know if they exactly
support this device or not). As such I have added {
USB_DEVICE(USB_VENDOR_ID_ION_TUSB3410,
ION_DEVICE_ID_TI_EDGEPORT_1_TUSB3410) } to edgeport_1port_id_table [] in
io_ti.c file, to handle Vend/Prod ID 0x451/0x341a for the device.
But still the device is not identified by the kernel when I plug it.
When Plugged, it says:

Try using the ti_usb_3410_5052.c driver instead. And you will have to
add your device id to the driver as that device currently isn't
supported by any Linux driver that I can find, sorry.

I don't know whether it is actually possible to get the kernel to associate the console with /dev/ttyUSB0. In the meantime, I am now attempting to get netconsole working. Any idea whether: 1) I can assist getting the F5U012 serial port working? I am a tester, not a coder. Load the driver with: modprobe mct_u232 debug=1 and send us the kernel debug log messages for when you try to use the device. 2) It is possible to set up the console to dump info to /dev/ttyUSB0? Yes, but I would not recommend it. Only do it as a last result, with a device that you know already works properly with Linux. thanks, greg k-h Using Tomcat but need to do more?

Since the devices are with differences vendor ID and product ID. With these changes your driver recognizes all of your mobile devices. I hope you understand this. Regards, Shalini G Shalini, Thanks for your advice. I couldn't find USB_DEVICE_INFO macro. Could you let me know where it is? If it doesn't exit, could you let me know where and how to create it? It's in the kernel header file, include/linux/usb.h. What kernel version are you looking at? Basically, we would like the usbserial driver to recognized vendor1/product1, vendor2/product2. Then please create a custom usb-serial driver. The generic driver is not to have any specific vendor ids for it. An example of the kind of driver you want is the funsoft.c driver that is in the 2.6.17-rc6 kernel. thanks, greg k-h ___ Linux-usb-users@lists.sourceforge.net To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users

It works fine but we noticed the speed is much lower than expected. Which usb-serial driver, the generic one? If so, yes, that's expected :) Then we changed the buffer size to a static 2048 bytes in usb-serial.c and the mobile transfer speed is very good. Is this the proper way to do it? A simple search of the archives would show that this is not the way to do it. Another question: we have more than one 3G mobiles in the same system, each have a different vendorID/productID. But usbserial can only load one id per machine. Any suggestion how to modify the usbserial driver to allow multiple vendorID/productID? Ah, you are using the generic driver, don't. Create a new usb-serial drivr for this device, which will allow you to increase the data rates and handle more devices properly. The generic driver is not ment for real workloads like you are trying to use it for. thanks, greg k-h ___ Linux-usb-users@lists.sourceforge.net To unsubscribe, use the last form field at: https://lists.sourceforge.net/lists/listinfo/linux-usb-users

If the device is bound to the driver, yes. But based on the output of the above file, it isn't. I suggest asking the vendor what the protocol is to talk to this device, so you can use it on Linux.
