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?
