** Description changed: 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? lspci 06:00.0 USB controller: Etron Technology, Inc.
