Attaching an usb 1.1 (sound ) device to an usb3 port results in not enough bandwidth
Hi all, Attaching an usb 1.1 device ( Funcube dongle pro+ ) results in an not enough bandwidth and some error messages from the xhci driver. (See attachment in bugzilla #60581 ) The device is not usable. The device works without any problems with ehci or ohci drivers.
