USB controllers are not recognized on Ubuntu Studio 16.04 LTS on a Gigabyte GA-990FXA-UD5 system [on chip 2.0 controller (via AMD SB950) and external onboard 3.0 controller (Etron EJ168)]. Changing EFI values in BIOS has no effect - system performs nominally within Win8.1. DVD boots (EFI and legacy load) the live system where no USB devices are recognized. USB stick boots (EFI and legacy) with a menu but soon ends with the following msg: [ 4.667018] usb 4-3: device descriptor read/64, error -32 [ 4.896013] usb 4-3: device descriptor read/64, error -32 [ 5.248018] usb 4-3: device descriptor read/64, error -32 [ 5.477047] usb 4-3: device descriptor read/64, error -32 [ 6.105027] usb 4-3: device not accepting address 4, error -32 [ 6.632023] usb 4-3: device not accepting address 4, error -32 [ 6.632068] usb usb4-port3: unable to enumerate USB device - BusyBox v1.22.1 (Ubuntu 1:1.22.0-15ubuntu1) built-in shell (ash) Enter 'help' for a list ob built-in commands.
