Re: XHCI issues: WD MyBook 1230 - reset SuperSpeed USB device
Gentlemen, I believe I've found the root cause of the issue. USB is absolutely not to blame in this case. Problems were caused by the udisksd daemon that sent ATA IDENTIFY DEVICE pass through command with the SECTOR_COUNT field set to 0 (cdb[6] = 0). I first noticed it when I compared the strace output from udiskd to the strace of smartctl and sg_sat_identify - both these tools set the cdb[6] to 1. After correcting the udiskd sources in this aspect, the problem appears to be solved. My sincere thanks to all of you - all your suggestions and comments moved me in the right direction. I will report this issue to udiskd maintainers along with the (trivial) patch. Once again, thanks!

It appears to have come from some user program, though, not the kernel. Possibly something run by udev. Probably smartd. The logic there is _less_ than perfect. Try to disable smartd and check if the issue remains.

I understand this is not a help desk with guaranteed replies but the fact that there was no response whatsoever is surprising to me. This means that nobody who has looked at your information knows what the problem is. I would like to at least kindly ask that someone looks at the traces and tells me if this is a possible software issue, or a hardware quirk that can hardly be worked around. A no, we won't fix this or even this is not the proper mailing list for this type of answer would be welcome at this point. It is kind of frustrating to report an USB-related issue to linux-usb mailing list, keep it updated, and yet receive absolutely no reaction in almost a month. If I knew how to fix this, I would - but I am no expert in USB stuff myself, so I am turning to experts... Nothing stands out in the logs. It may be a power management issue. Have you tried using a kernel with CONFIG_PM not set?

Re: XHCI issues: WD MyBook 1230 - reset SuperSpeed USB device
Greetings, Regarding the issue with WD MyBook 1230 stalling and being reset when connected to an HP EliteBook 8560p, I have tested the 3.13-rc7 kernel from kernel.org to no avail - the drive still stalls and is reset after a couple of seconds. I am attaching a dmesg output (relevant lines regarding the drive and the xHCI reset are at the end) and the usbmon trace. The lspci and lsusb outputs have been attached to the original mail I've opened this thread with (if necessary, I will gladly repost them). The usbmon trace covers the complete session with the drive, starting with its connection to my USB 3.0 slot, then accessing the drive with gdisk -l /dev/sdb, across its stall and reset, up to its physical disconnection. The actual transcript of the communication with the drive that ensued after the gdisk -l /dev/sdb command that led to the stall starts at the decimal offset 82582 in the usbmon trace file. Thank you!

XHCI issues: WD MyBook 1230 - reset SuperSpeed USB device
Greetings, I have an HP EliteBook 8560p, I am running Linux kernel 3.12.3, and I am trying to connect a WDC MyBook 1230 3TB SuperSpeed USB hard drive to the notebook. I am often (though not consistently) having problems with the access to the drive stalling for several seconds, and the kernel resetting the device afterwards: usb 2-2: reset SuperSpeed USB device number 2 using xhci_hcd xhci_hcd :26:00.0: xHCI xhci_drop_endpoint called with disabled ep 880412adf480 xhci_hcd :26:00.0: xHCI xhci_drop_endpoint called with disabled ep 880412adf4c0 Sometimes a single kernel-issued reset is enough to allow the disk to be accessed without problems until physically disconnected, in another instances, this problem simply repeats itself as the drive is accessed. When the drive decides to cooperate, the transmission speeds are stable and solid - in excess of 120 MB/s. So far, I have not been able to pinpoint the exact circumstances under which the problem remains persistent even across kernel-issued USB resets. I am attaching a series of outputs: - dmesg output after the drive was connected and a gdisk -l /dev/sdb command was issued to print out the partition table of the disk, prompting the problem to appear - lspci and lspci -v outputs - lsusb and lsusb -v outputs - usbmon capture, logging the entire session with the drive being connected to the notebook, and issuing gdisk -l /dev/sdb command as noted above Any and all help is greatly appreciated! I will gladly perform whatever experiments are necessary to track down the cause of this problem. Best regards, Peter files.tar.bz2 Description: application/bzip
