Adrian, I certainly would not think of killing anyone. I don't think anyone else on the list would, either. But your problems with the hard drivers are in fact an object lesson about flaky and barely-within-spec or barely-out-of-spec hardware. The problems are indeed very vexing and are quite difficult to isolate. I am glad that a couple of us actually began to suspect the hardware. It seems that those suspicions panned out, and all is well that ends well. Even though I was not the first to pinpoint the problem, I had been reading this thread and the other post which raised the issue of hardware problems really got my spider-sense tingling. I started to remember some of my own experiences. Two of them immediately come to mind and might serve as a further object lesson to anyone who passes by and reads this: 1. A camera with the SQ913 camera chipset inside. My camera, which was used to write the driver code in libgphoto2, worked just fine on a Dell Pentium 3 system and on an old laptop with an OHCI setup for its USB, and refused to work properly on any of several computers in the house which ran an AMD cpu on top of a VIA-based motherboard. On those systems, severe data loss, data corruption, and actual crashing occurred while downloading still photos from the camera. Putting a magnetic core around the cable helped a little bit, but the problem did not go away. So, again, an example of a poor specimen of hardware hooked by a cheap cable to a cheap motherboard, and there was trouble. To this day I have no way to pinpoint the exact cause of the problem. 2. I forget which dual-mode camera it was, but it is one of those for which I wrote the kernel support. I discovered the problem at the worst possible time: after already writing the code and submitting same, and it actually went into a production kernel. When I found the problem, it was too late to get anything changed until the next release date. What was the problem? Well, the camera needs several mysterious initialization commands to start the video stream. Some of these were obviously superfluous and could be safely left unused. But I left out one too many. I developed the driver on an AMD system with ATI USB host controllers. Everything worked, and the code was duly submitted. Then, too late, I tested on a Pentium4-on-Intel system. There, the video stream would not start, or it would start and speedily crash. When I put back into the driver that pesky one too many omitted init string, the camera worked on an Intel setup, too. What exactly does that one command do? I don't exactly know. Precisely what caused the problem? I don't know. All I can say for sure is that the Intel (UHCI) system needed for a certain setup command to be sent to the camera, whereas the ATI (OHCI) system did not. And that is, in fact, something very strange. Go figure. We are working with computers. Weird stuff is not supposed to happen. But it does. Occasionally, this needs to be remembered, as it does occasionally cause real-world problems and is often the likely explanation for what is otherwise inexplicable. Thus, sooner or later some old geezer comes along and reminds people that Murphy is still around to do his mischief. I am glad that my suggestions turned out to be helpful.

Adrian Sandu wrote: I wouldn't of expected this from WD .. Like with Theodore's problem you don't really know for sure where the problem was in your setup. Any combination of USB controller hardware in PC, cable, and electronics in drive enclosure can have caused your problem. External disk drive now cost *less* than the exact same model internal drive, so you are actually *getting paid* to receive interface electronics, power supply, some plastic, metal and rubber that makes up the enclosure, cabling, and packaging.

Of course, perhaps Seagate stuff is always better. Or Microsoft. Or Apple. Or ...??? (:-) Specs and standards are for violating, you know. Or that is what some people think. It has been that way from the beginning of time. But what would be the solution? To have neither specs nor standards? One wouldn't expect that to work out too well, either. Peter Stuge's comments are quite relevant, too. He is probably right about the category of external hard drives, these days. Indeed, they seem too good of a bargain. But maybe we are the ones who are fooled and it is the internal hard drives which are overpriced. Who knows? Anyway, one of the things which makes life really complicated for too many of us is, the statement that you get what you pay for is not necessarily true, either. It happens sometimes that some fly-by-night or Brand X company is making and selling the best product on the market in some category, but they can't charge nearly as much money as the so-called reputable producers and vendors precisely because they have no brand recognition. So one never knows.

Re: [usb-storage] Re: usb3 fails to write when using usb3 hub in usb3 port
Adrian, I think that the suggestion about checking the power supply, the cabling, the grounding screws, and anything of like nature that has been omitted from this list is a very good idea. If successful it would eliminate the problem for you, as well as resolving the mystery. Unresolved mysteries are unpleasant for the user, and at least equally unpleasant for a developer. I have seen hardware do really weird things, myself. As a trivial example, once a local computer shop gave me a motherboard which had been returned because of booting problems. I was told that it had been brought in twice by the customer. No problem had been detected in the shop; they had replaced it to make a customer happy. I brought the board home. It was a hot summer day. I put it on the floor, hooked up a spare power supply, and it booted. No problem. I left it sitting there overnight. The next morning, I tried it again. Dead. But in the evening it came to life again. Guessing, I looked at the solder joints under the power connector on the board. One of them looked suspicious. So I fired up the soldering iron and put a dab of fresh solder on it. After that, the board was in use for years and never had the booting problem again. The reason that the problem was not detected was that it was the middle of the summer in Alabama, and when the computer was brought to the shop it was put in a car for the trip. The board got warm enough for the solder in that joint to expand enough for startup, while en route to the shop. Thus, I definitely do encourage you to check for hardware or cabling problems before deciding to buy additional equipment as a workaround.

Re: [usb-storage] Re: usb3 fails to write when using usb3 hub in usb3 port
Adrian, I think that the suggestion about checking the power supply, the cabling, the grounding screws, and anything of like nature that has been omitted from this list is a very good idea. If successful it would eliminate the problem for you, as well as resolving the mystery. Unresolved mysteries are unpleasant for the user, and at least equally unpleasant for a developer. I have seen hardware do really weird things, myself. As a trivial example, once a local computer shop gave me a motherboard which had been returned because of booting problems. I was told that it had been brought in twice by the customer. No problem had been detected in the shop; they had replaced it to make a customer happy. I brought the board home. It was a hot summer day. I put it on the floor, hooked up a spare power supply, and it booted. No problem. I left it sitting there overnight. The next morning, I tried it again. Dead. But in the evening it came to life again. Guessing, I looked at the solder joints under the power connector on the board. One of them looked suspicious. So I fired up the soldering iron and put a dab of fresh solder on it. After that, the board was in use for years and never had the booting problem again. The reason that the problem was not detected was that it was the middle of the summer in Alabama, and when the computer was brought to the shop it was put in a car for the trip. The board got warm enough for the solder in that joint to expand enough for startup, while en route to the shop. Thus, I definitely do encourage you to check for hardware or cabling problems before deciding to buy additional equipment as a workaround.

On Wed, Sep 26, 2012 at 5:50 PM, Alan Stern st...@rowland.harvard.edu wrote: On Tue, 25 Sep 2012, Sarah Sharp wrote: Alan, I'm wondering if the xHCI ring expansion is causing issues with USB hard drives under xHCI. Testing with a Buffalo USB 3.0 hard drive with an NEC uPD720200 xHCI host, I see that the usb-storage and SCSI initialization produces I/O errors on random sectors in 3.4.0, 3.4.6, and 3.5.0. I can't get those errors to be reproduced in 3.3.1. The xHCI ring expansion was added in 3.4, and we changed the xHCI's sg_tablesize: int xhci_gen_setup(struct usb_hcd *hcd, xhci_get_quirks_t get_quirks) { ... /* Accept arbitrarily long scatter-gather lists */ hcd-self.sg_tablesize = ~0; The usb-storage driver sets the tablesize thus: static unsigned int usb_stor_sg_tablesize(struct usb_interface *intf) { struct usb_device *usb_dev = interface_to_usbdev(intf); if (usb_dev-bus-sg_tablesize) { return usb_dev-bus-sg_tablesize; } return SG_ALL; } I notice that SG_ALL is set to SCSI_MAX_SG_SEGMENTS, which is only 128. Should we be passing an arbitrarily large number to the SCSI core? Yes, there's no reason not to. The block layer will make sure that each individual request has a sufficiently small number of segments. There's some wording in include/scsi/scsi.h about also limiting the number of chained sgs to 2048. I'm wondering if we're hitting some bugs in the SCSI layer because we're setting the sg_tablesize so high. I doubt it. Anyway, this stuff is handled by the block layer now, not the SCSI layer. If you look through drivers/scsi, you'll see that SG_ALL is used only in various SCSI interface drivers, not in the core. Alternately, we could be hitting bugs in the USB 3.0 firmware when we attempt to issue a read or write that's too big. The read on Adrian's hard drive failed on a bigger read request (122880 bytes). It would be interesting to see if it works fine if the xHCI sg_tablesize is limited. I'm going to try that with my own drive on 3.5.4 and see if it helps. There were examples in the earlier usbmon traces where 122880-byte reads succeeded, for whatever that's worth... I doubt very much that you are anywhere close to hitting that limit. If a 120-KB transfer has more than 128 SG segments then on average each segment would be under 1024 bytes, a lot smaller than a page, which seems unlikely. I don't think I've ever seen a transfer needing more than about 8 segments. Alan Stern Ok, back to vanilla 3.4.11, disabled CONFIG_USB_XHCI_HCD_DEBUGGING ..
