Hi, this is your Linux kernel regression tracker speaking. I noticed a bugreport from Tomasz C. (CCed) that sounds a lot like a regression between v5.15.7..v5.15.8 and likely better dealt with by email: To quote from: https://bugzilla.kernel.org/show_bug.cgi?id=215341 > After updating kernel from 5.15.7 to 5.15.8 on ArchLinux distribution, Holtek USB mouse stopped working. > Exact model: > 04d9:a067 Holtek Semiconductor, Inc.

[TLDR for the rest of the mail: adding this regression to regzbot; most text you find below is compiled from a few templates paragraphs some of you might have seen already.] 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 v5.15.7..v5.15.8 #regzbot title usb: Holtek mouse stopped working Reminder: when fixing the issue, please add a 'Link:' tag with the URL to this report and the bugzilla ticket, then regzbot will automatically mark the regression as resolved once the fix lands in the appropriate tree. For more details about regzbot see footer. Ciao, Thorsten (wearing his 'Linux kernel regression tracker' hat). 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 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.
