Re: Webcam become sda [SOLVED]

What makes you believe it's the webcam and not the realtek or jmicron device? (Though one of them is likely sdb)

lsusb -tv

will list the ports (matching the usb-0:6:1.0) and tell.

It is the Realtek SD card reader. When I try to use it for some reason a new device apper. If I disable the sd card reader in the bios sda disappear.
If I disable the webcam the sd card reader start to work under sda.

Re: Webcam become sda [SOLVED]

This is probably completely down to the card reader, please post comparative system journals (w/ and w/o webcam enabled) coevering attempts to use the card reader.

sudo journalctl -b | curl -F 'file=@-' 0x0.st

Or for the previous boot

sudo journalctl -b -1 | curl -F 'file=@-' 0x0.st

Re: Webcam become sda [SOLVED]
