Laptop Asus Integrated Webcam is disabled

Question

I've searched around google for this problem, but all solutions weren't successful on my PC.

So the situation is this:

    :~$ lsusb
Protocol spec without prior Class and Subclass spec at line 17509
Bus 001 Device 002: ID 8087:8000 Intel Corp. 
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 003 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 002 Device 003: ID 0bda:0129 Realtek Semiconductor Corp. RTS5129 Card Reader Controller
Bus 002 Device 002: ID 04ca:3010 Lite-On Technology Corp. 
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

As you can see lsusb doesn't read the webcam BUT:

    :~$ dmesg | grep video
[    9.046002] asus_wmi: Backlight controlled by ACPI video driver
[  444.990641] Linux video capture interface: v2.00
[  445.046291] usbcore: registered new interface driver uvcvideo
[  709.912127] uvcvideo: Found UVC 1.00 device USB Camera (0bda:57b5)

dmesg does.

So, I read that could be a shortcut that I pressed by mistake.

Like Fn+v, but didn't work.

Solution

Comment out line beginning with GRUB_CMDLINE_LINUX_DEFAULT="quiet...." and put the below instead. Afterwards, run sudo update-grub and reboot.

sudo gedit /etc/default/grub

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash usbcore.autosuspend=-1 acpi_enforce_resources=lax"

In case it doesn't work, run this command in a terminal:

sudo bash -c 'echo -1 > /sys/module/usbcore/parameters/autosuspend'

Reboot. Good luck.

I cannot even find the Camera device in dmesg
