Hey there,
I am having some troubles with my new acer laptop with a just bought a couple of months ago and installed ubuntu 22.04.
I have been using ubuntu for some year now already, and although I am not very good or experience when using the terminal, this is the first time I come up with a hardware problem that I can't seem to solve.
So basically my builtin webcam won't work, and when I open cheese or any other webcam app, it says "no device detected". However, it was working when I bought and the seller tested it with me, when it was still on Windows.
I have an old usb webcam here which happens to work just fine.
I usually wouldn't mind so much, but especially after covid I need to give several talks and classes online, so I was hoping someone could help me.
Here is my lsusb output (it detects the webcam):
Code:

dmesg output:
Code:
[ 3.464886] uvcvideo 3-7:1.1: Failed to query (129) UVC probe control : 26 (exp. 48).
[ 3.464919] uvcvideo 3-7:1.1: Failed to initialize the device (-5).

I went to linux-hardware and created a probe. However, there already seems to be a kernel module:
Code:
/usr/include/linux/uvcvideo.h
/usr/include/linux/usb/g_uvc.h
/usr/lib/modules/5.15.0-25-generic/kernel/drivers/media/usb/uvc
/usr/lib/modules/5.15.0-25-generic/kernel/drivers/media/usb/uvc/uvcvideo.ko
/usr/lib/modules/5.15.0-25-generic/kernel/drivers/usb/gadget/function/usb_f_uvc.ko
/usr/lib/modules/5.15.0-41-generic/kernel/drivers/media/usb/uvc
/usr/lib/modules/5.15.0-41-generic/kernel/drivers/media/usb/uvc/uvcvideo.ko
/usr/lib/modules/5.15.0-41-generic/kernel/drivers/usb/gadget/function/usb_f_uvc.ko
I hope someone can help me with this, and thank you already to whoever takes their time to read it.
Cheers
