Not only are the devices no longer available on the host, but no power is drawn by them. Only a reboot fixes the problem. The scanner is the only device that triggers the problem, even when it is the only device plugged in. I have a host of other devices, connected either directly or via a USB hub in my monitor: - keyboard - mouse - logitech brio webcam - yubikey - stream deck - microphone None of these cause any issues. I have tried the following kernels ( packaged for openSUSE Tumbleweed ), and none of them fixed the issue: - 5.15.2 - 5.15.5 - 5.16~rc3-1.1.ge8ae228 The problem does not appear if the scanner is connected when the laptop is shutdown. It seems to have an init phase of about 6-7 seconds (blinking green led) and then stays on. However, it is not detected via lsusb or scanimage -L. The problem does not appear on a desktop class machine ( ASUS Prime X470-PRO/Ryzen 3700x). The relevant parts of the kernel log seem to be: Nov 22 11:53:18 rombert kernel: xhci_hcd 0000:00:14.0: Abort failed to stop command ring: -110 Nov 22 11:53:18 rombert kernel: xhci_hcd 0000:00:14.0: xHCI host controller not responding, assume dead Nov 22 11:53:18 rombert kernel: xhci_hcd 0000:00:14.0: HC died; cleaning up I've initially reported this at https://bugzilla.opensuse.org/show_bug.cgi?id=1192569 and CC'ed the distribution's kernel maintainer. Please let me know if additional information is needed. Regards, Robert Munteanu ^ permalink raw reply [flat|nested] 13+ messages in thread

Thanks for the report. Top-posting for once, to make this easy accessible to everyone. FWIW, 5.14 is EOL, so it might not be fixed there. As the problem is in newer kernels as well, I suspect that it was a change applies to 5.15 or 5.16 that got backported. Maybe one of the developers might have an idea which commit causes it. If that's not the case you likely should try a bisection to find the culprit. Performing one between v5.14.11..v5.14.14 is likely the easiest and quickest way to find it. To be sure this issue doesn't fall through the cracks unnoticed, I'm adding it to regzbot, my Linux kernel regression tracking bot: #regzbot ^introduced v5.14.11..v5.14.14 #regzbot title usb: plugging in USB scanner breaks all USB functionality [regression present in 5.15.2 und 5.16-rc3, too] #regzbot ignore-activity Reminder for developers: when fixing the issue, please add a 'Link:' tag with the URL to the report (the parent of this mail), then regzbot will automatically mark the regression as resolved once the fix lands in the appropriate tree. For more details about regzbot see footer. Sending this to everyone that got the initial report, to make all aware of the tracking. I also hope that messages like this motivate people to directly get regzbot involved when dealing with regressions, as messages like this wouldn't be needed then. Don't worry, I'll send further messages wrt to this regression just to the lists (with a tag in the subject so people can filter them away), as long as they are intended just for regzbot. With a bit of luck no such messages will be needed anyway. Ciao, Thorsten, your Linux kernel regression tracker. P.S.: As a Linux kernel regression tracker I'm getting a lot of reports on my table. I can only look briefly into most of them. Unfortunately therefore I sometimes will get things wrong or miss something important. I hope that's not the case here; if you think it is, don't hesitate to tell me about it in a public reply. That's in everyone's interest, as what I wrote above might be misleading to everyone reading this; any suggestion I gave they thus might sent someone reading this down the wrong rabbit hole, which none of us wants. BTW, I have no personal interest in this issue, which is tracked using regzbot, my Linux kernel regression tracking bot (https://linux-regtracking.leemhuis.info/regzbot/). I'm only posting this mail to get things rolling again and hence don't need to be CC on all further activities wrt to this regression. --- Additional information about regzbot: If you want to know more about regzbot, check out its web-interface, the getting start guide, and/or the references documentation: https://linux-regtracking.leemhuis.info/regzbot/ https://gitlab.com/knurd42/regzbot/-/blob/main/docs/getting_started.md https://gitlab.com/knurd42/regzbot/-/blob/main/docs/reference.md The last two documents will explain how you can interact with regzbot yourself if your want to. Hint for reporters: when reporting a regression it's in your interest to tell #regzbot about it in the report, as that will ensure the regression gets on the radar of regzbot and the regression tracker. That's in your interest, as they will make sure the report won't fall through the cracks unnoticed. Hint for developers: you normally don't need to care about regzbot once it's involved. Fix the issue as you normally would, just remember to include a 'Link:' tag to the report in the commit message, as explained in Documentation/process/submitting-patches.rst That aspect was recently was made more explicit in commit 1f57bd42b77c: https://git.kernel.org/linus/1f57bd42b77c On 02.12.21 15:55, Robert Munteanu wrote: > Hi, > > After updating from kernel 5.14.11 to 5.14.14 I am seeing the following > problem: > > When plugging in an USB scanner ( Brother DSMobile DS-740D ) to my > Lenovo P52 laptop I lose connection to all USB devices.

A full bisect run, as suspected in other messages, results in e54abefe703ab7c4e5983e889babd1447738ca42 is the first bad commit commit e54abefe703ab7c4e5983e889babd1447738ca42 Author: Pavankumar Kondeti <pkondeti@codeaurora.org> Date: Fri Oct 8 12:25:46 2021 +0300 xhci: Fix command ring pointer corruption while aborting a command commit ff0e50d3564f33b7f4b35cadeabd951d66cfc570 upstream. The command ring pointer is located at [6:63] bits of the command ring control register (CRCR). All the control bits like command stop, abort are located at [0:3] bits. While aborting a command, we read the CRCR and set the abort bit and write to the CRCR. The read will always give command ring pointer as all zeros. So we essentially write only the control bits. Since we split the 64 bit write into two 32 bit writes, there is a possibility of xHC command ring stopped before the upper dword (all zeros) is written. If that happens, xHC updates the upper dword of its internal command ring pointer with all zeros. Next time, when the command ring is restarted, we see xHC memory access failures. Fix this issue by only writing to the lower dword of CRCR where all control bits are located.
