Hi.

I am using a Z21 with an Ubuntu 11.10 (1). What is not working well is 
the support for USB. My USB 3 port is currently not working at all (not 
with USB 2 or USB 3 devices).

Major issue: USB 3 port not working
___
I could live without USB 3 support, while my USB 3 port would act as an 
USB 2 port. This used to work after installing Ubuntu, but stopped 
working some weeks ago.

Minor issue: USB 2 port not reliable
___
Using a passive USB 2 hub at my USB 2 port works, but sometimes all 
attached USB devices stall for three to five seconds.

Minor issue: USB hard drive auto-mount fails
___
Corresponding to the fail of my USB 3 port, the auto-mount for one 
specific USB hard drive stopped working. Is there a way I could debug this?

Did anyone else experience this issues?
