Feb 28 17:11:34 euphony kernel: xhci_hcd 0000:04:00.0: ERROR: unexpected command completion code 0x11.
Feb 28 17:11:34 euphony kernel: usb 5-1.1: Not enough bandwidth for altsetting 1

Completion code 0x11 (17) is parameter error, this means some value in
a context parameter is invalid.

Many of these context parameter are taken from the descriptors of the
attached usb device  (device, interface, endpoint descriptors)

More details are needed, output of "lsusb -v", and dynamic debug of
xhci and usbcore would be a good start
