Title:
xhci usb 3.0 logitech c920 not working
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
Hello,
my usb webcam logitech c920 doesn't work when connected to my usb 3.0
host controller (Etron EJ168a). when connected to a usb 2.0 host
controller it works perfectly. when i connect my usb 3.0 stick to the
same port it's recognized and also works - just not the webcam.
disabling usb 3.0 legacy mode (xhci) in my bios doesn't change
anything, it's still used instead of ehci. kernel problem?
