Same hardware,two debian-11.7 installed in the same pc ,one is on /dev/sda1,other is on /dev/ada2.
For the debian on /dev/sda1:
Code:
uname -a
Linux debian 5.10.0-22-amd64 #1 SMP Debian 5.10.178-3 (2023-04-22) x86_64 GNU/Linux
sudo dmesg | grep uvc
[ 16.378883] uvcvideo: Found UVC 1.00 device Lenovo FHD Webcam Audio (17ef:4831)
[ 16.397414] usbcore: registered new interface driver uvcvideo
ls /dev/video*
/dev/video0 /dev/video1
lsmod | grep video

I can use the usb camera with cheese or other video soft.
For the debian on /dev/sda2:
Code:
uname -a
Linux debian 5.10.0-23-amd64 #1 SMP Debian 5.10.179-2 (2023-07-14) x86_64 GNU/Linux
sudo dmesg | grep uvc
#nothing in the output
ls /dev/video*
#nothing in the output
lsmod | grep video
video 61440 0
Can't use usb camera with cheese,how can install and load lost mod in /dev/sda2's debian?
