After running Powertop to do some tests with power usage, I realised that I have two USB devices listed that are not actually in use and that I would like to remove completely from my system.
USB device: usb-device-8087-0a2b USB device: XiaoMi USB 2.0 Webcam (SunplusIT Inc)
When I installed Ubuntu I checked the option to automatically install drivers, so I'm going to suppose that's where these two came from.
Is there a way I can
- Understand what the first one is
- Figure out the drivers connected to both
- Remove those drivers so that they wouldn't get activated anymore
I don't have any other information about what they could be and nothing else is connected via USB to the laptop.
I'm on Ubuntu 18.04.01 LTS
Edit: I checked in System Monitor and I can't find anything that could be related to them.
Edit 2: Running
for device in $(ls /sys/bus/usb/devices/*/product); do echo $device;cat $device;done
/sys/bus/usb/devices/1-5/product XiaoMi USB 2.0 Webcam
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 004: ID 8087:0a2b Intel Corp. Bus 001 Device 003: ID 04f3:0c1a Elan Microelectronics Corp.

Which should be the first
echo '1-5' | sudo tee /sys/bus/usb/drivers/usb/unbind
1-5 tee: /sys/bus/usb/drivers/usb/unbind: No such device
