http://bugzilla.opensuse.org/show_bug.cgi?id=1207347 http://bugzilla.opensuse.org/show_bug.cgi?id=1207347#c7 --- Comment #7 from Takashi Iwai --- In the broken case, we see the message: [ 8.258316] xhci_hcd 0000:06:00.0: failed to load firmware renesas_usb_fw.mem, fallback to ROM which means my previous patch is working. But by some reason, the XHCI driver couldn't detect the device properly. You can try to install older kernels (5.14 and later) and see whether it's working without the firmware. If yes, there is a regression between the versions. The older kernels can be found at my OBS repos, e.g. OBS home:tiwai:kernel:5.14, home:tiwai:kernel:5.15, ... It's possible that the device worked in the past just casually. But it might be worth to verify. BTW, instead of running the command, you can simply put the firmware file as /lib/firmware/renesas_usb_fw.mem, and rebuild initrd. That should suffice for the next reboot. -- You are receiving this mail because: You are the assignee for the bug.

The latter shouldn't make any difference to version 1.35 in this case, because I don't see any fixes regarding the webcam. -- You are receiving this mail because: You are the assignee for the bug.

The work without the firmware is rather casual, just a best-effort result. So, this is likely a WONTFIX bug, but it's still interesting if it's really a regression in kernel. We may close it once after figuring it out. -- You are receiving this mail because: You are the assignee for the bug.
