Description Richard Marko 2011-10-12 12:21:20 UTC 
Description of problem:
USB stops working after dock undock cycle. Furthermore it isn't possible to suspend the machine to restore the functionality.

Version-Release number of selected component (if applicable):
# uname -a
Linux dhcp-0-229.brq.redhat.com 2.6.32-206.el6.x86_64 #1 SMP Tue Oct 4 11:51:32 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

How reproducible:
Always

Steps to Reproduce:
1. attach USB mouse & keyboard to the docking station
2. dock the machine, boot to el6.2 (livecd used for this)
3. undock
4. dock again
5. suspend
  
Actual results:
After step 4. USB mouse and keyboard isn't working, reattaching these to docking station isn't helping.

Suspend isn't working either - lots of traces present in dmesg

Expected results:
USB devices working. Suspend working.

Not only USB ports on docking station but even on the machine itself are disabled after the cycle.
