Title:
USB controllers are not recognized (live and install 16.04 Xenial)
Status in linux package in Ubuntu:
Expired
Bug description:
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.
(initramfs) Unable to find a medium containing a live file system
Last but not least Ubuntu Studio cant be installed due to other bugs
(LAN failure and EFI grub installation abort).
WORKAROUND: Set in the BIOS:
xHCI handoff - Disabled (was Enabled)
EHCI handoff - Disabled
IOMMU controller - Enabled (was Disabled)
