On Thu, 1 Sep 2005, Andy Stewart wrote: After further experimentation, I'm no longer convinced that anything is faster on my Opteron vs. the laptop. I was using Konqueror to drag-drop files to the MP3 player, and was gauging the speed based on the Konqueror progress window. After many experiments, the time to copy a large file appeared to approach zero (clearly impossible). I suspect some sort of caching effect since a 'sync' command would typically take several minutes to return to the command prompt. This leads me to ask if there is an application similar to iptraf that can show USB traffic details. How about hdparm for data transfer timings? Or even something as simple as: time sh -c 'dd ... ; umount /dev/sda1' For USB traffic details there is the usbmon facility available in the kernel, described in Documentation/usb/usbmon.txt. Now, I can't reliably access the G3 (or my Epson scanner) when it is plugged into the EHCI port, but that is the subject of a future thread. What do you mean by the EHCI port? Remember, on a high-speed system each port is generally connected to two types of controller: the EHCI controller and a companion full/low-speed UHCI or OHCI controller. That's how your motherboard is set up. While doing these experiments, I was using the 'usbview' GUI. In my case, usbview lists 1 EHCI controller, 3 UHCI controllers, and 1 OHCI controller. The OHCI controller is your add-on card, so we can ignore it. The other controllers are on the motherboard. I have 6 physical USB connectors on my system. Usbview lists the device underneath the controller to which it is connected. There are only 2 connectors on my system where devices show up as being connected to the EHCI host controller (I called those EHCI ports). If I plug a USB 2.0 device into an EHCI port, I expect to see USB 2.0 speeds when accessing that device (taking device limits into account). All 6 ports are connected to the EHCI controller, and each UHCI controller is connected to 2 of the ports. So all your motherboard ports are both EHCI and UHCI. Try plugging a non-high-speed device into one of those so-called EHCI ports and you'll see what I mean. Also check out the MaxCh (Max-Children) field in the T: line of /proc/bus/usb/devices for each controller. You'll see that each UHCI controller can have 2 children while the EHCI controller can have 6. You need to get over your confusion between USB 2.0 and a device's speed. USB 1.1 defines two speeds: low (1.5 Mb/s) and full (12 Mb/s). USB 2.0 defines three speeds: low, full, and high (480 Mb/s). A USB 2.0 device is free to use whichever speed it wants. (Except hubs; a USB 2.0 hub _must_ run at high speed if the upstream port is capable of supporting it.) What this means is that plugging a USB 2.0 device into one of your motherboard ports guarantees nothing about the speed. But if you plug a high-speed-capable device into any of those ports, it should run at high speed. EXCEPT that in many computers, some of the internal wiring (particularly the cables that lead from the motherboard to the ports at the front of the case) is not good quality and is too noisy for use at high speed. Try to do it and you'll encounter many errors and eventual failure. My scanner and MP3 player support USB 2.0, and this fact is recognized by usbview when I click on each device when it is connected to the EHCI host controller. However, what I have noticed is that neither my scanner nor my MP3 player work reliably when plugged into the EHCI host controller. Small data transfers work OK, but large ones (perhaps 5 MB) return errors, after which the device is inaccessible until unplugged and plugged in again (not power cycled, but dis/reconnected to USB). In your case, it could be that _all_ the wiring is somewhat noisy. You might try using the 2.6.13 kernel; it has improved error recovery in usb-storage. These devices work great when plugged into either the OHCI or UHCI controller. Why might this be? What can I do to gather more useful debug information? Slower transfers are more resilient against noise than fast ones. If noise is indeed the culprit, there's not much you can do about it -- improve the computer's internal wiring perhaps. Or you could replace your PCI USB card with one that has an EHCI controller; it ought to work better than the one on the motherboard.

HI Alan, I tried using the 2.6.13 kernel but the results are the same - high speed devices work OK with OHCI or UHCI, but not with EHCI.

Re: [linux-usb-devel] MP3 player iAudio G3 doesn't work on 2.6.12.3
HI Alan et al, I believe that I have solved the problem (at least for USB 1.x) while using the 2.6.12.3 kernel. In summary, I changed two things at once (yeah, I know I shouldn't do that): 1) I added a pci-usb controller with a different chipset 2) I compiled/installed the ehci-hcd kernel module Compiling and installing the ehci-hcd module shouldn't make any difference. But if you rebuilt the entire kernel instead of just that one module, then maybe something else could have changed. My USB hardware on the dual Opteron server: # lspci -v | grep -i usb #add on pci-usb controller :00:08.0 USB Controller: OPTi Inc. 82C861 (rev 10) (prog-if 10 [OHCI]) It's a little unusual to come across a PCI USB card that includes an OHCI controller without an EHCI controller. # these are from the motherboard chipset :00:10.0 USB Controller: VIA Technologies, Inc. VT82x UHCI USB 1.1 Controller (rev 81) (prog-if 00 [UHCI]) :00:10.1 USB Controller: VIA Technologies, Inc. VT82x UHCI USB 1.1 Controller (rev 81) (prog-if 00 [UHCI]) :00:10.2 USB Controller: VIA Technologies, Inc. VT82x UHCI USB 1.1 Controller (rev 81) (prog-if 00 [UHCI]) :00:10.4 USB Controller: VIA Technologies, Inc. USB 2.0 (rev 86) (prog-if 20 [EHCI]) Previously, I had neither compiled the ehci-hcd.ko module nor had I enabled USB 2.0 on my motherboard (the motherboard allows one to select USB 1.0 or USB 2.0). Since the iAudio G3 supposedly supports USB 2.0, I thought I would try enabling USB 2.0. I compiled and loaded ehci-hcd and now I can mount and access the iAudio G3 reliably on the UHCI and OCHI ports. Does it make sense that adding the ehci-hcd module should make this suddenly work even in USB 1.x mode? No, if by USB 1.x mode you mean that the USB 2.0 option in the BIOS remains turned off. But if that option is turned on and ehci-hcd is loaded then there's no way to force the motherboard ports to run at full (USB 1.1) speed -- other than plugging in a full-speed device. If ehci-hcd isn't loaded, then the only differences from your earlier environment are caused by: Whatever changes result from loading ehci-hcd at boot and then unloading it later (probably nothing important); Whatever other changes might have occurred as a result of rebuilding the entire kernel (only if you did rebuild the entire kernel, and even then there shouldn't be any such changes, although you never know); Whatever changes you might have made to the BIOS. The BIOS could easily have been the entire reason for your problems all along. I wouldn't be surprised if you found that the earlier OS version, without ehci-hcd compiled, also started working correctly once that setting was changed. And I wouldn't be surprised if you found that putting the BIOS setting back caused the problems on the motherboard ports to reappear, even with ehci-hcd loaded. I'm pleasantly surprised that the speed of access is *much* faster than on the laptop (on the order of 6x faster on writes). My CPU goes to 100% while accessing the G3, so it makes sense to me that a much faster processor (1.8GHz Opteron vs. 1.0 GHz Athlon) would help. Would you agree? No. At high (USB 2.0) speed, I/O transfers generally limited by the device, not by the CPU or the USB connection. Even though your CPU usage shows up as 100%, it's not at all clear that the CPU is doing anything useful at those times. Now, I can't reliably access the G3 (or my Epson scanner) when it is plugged into the EHCI port, but that is the subject of a future thread. What do you mean by the EHCI port? Remember, on a high-speed system each port is generally connected to two types of controller: the EHCI controller and a companion full/low-speed UHCI or OHCI controller.

Alan Stern HI Alan, I installed the 2.6.12.3 kernel on my laptop, and the iAudio G3 seems to work just fine. I'm leary of downgrading my kernel on the dual opteron since I had severe hang problems prior to 2.6.12.3, but I'll do it just for this experiment, while saving my desired kernel for afterwards. More news later. Thanks again for the help.
