Title:
HP Z640 USB port stopped working since 4.4.0-22.38
Status in linux package in Ubuntu:
Confirmed
Bug description:
On HP Z640 Workstations running ubuntu 16.04 with any official ubuntu
kernel newer than 4.4.0-21-generic USB devices do not work.
They appear to be listed correctly via lsusb and connects and
disconnects are logged but keyboards, mice, storage devices, ethernet
adapters do not work at all when they are connected directly via any
USB ports on the machines or through USB hubs.
All ubuntu packages are up to date. The BIOS version is the latest
(2.29).
The ubuntu 4.4.0-21.37 kernel works correctly as do older kernels from
ubuntu 16.04. Vanilla kernel.org kernels that I've tried such as
4.4.30 and 4.4.38 work correctly.
Ubuntu kernels greater than 4.4.0-21.37, from 4.4.0-22.38 all the way
to 4.4.0-59.80 and 4.8.0-34.36 are affected by this issue.
