[PATCH v1 5/8] media: uvcvideo: Quirk for autosuspend in Logi C910
From: Ricardo Ribalda
Date: Tue Sep 20 2022 - 10:09:02 EST
Logitech C910 firmware is unable to recover from a usb autosuspend. When
it resumes, the device is in a state where it only produces invalid
frames. Eg:
$ echo 0xFFFF > /sys/module/uvcvideo/parameters/trace # enable verbose log
$ yavta -c1 -n1 --file='frame#.jpg' --format MJPEG --size=1920x1080 /dev/video1

...(loop)...
The devices can leave this invalid state if its altstate is toggled.
This patch addes a quirk for this device so it can be autosuspended
properly.
