This is the second USB problem that we've heard dealing with this kernel.
There is a brand new bugfix kernel out today that said it deals with a USB bug.
"* USB devices would not be detected on a PowerEdge R805 system. USB devices
are now able to be detected on the aforementioned system with this update."
I'm wondering if it is more than the Poweredge systems having a problem.
I'm still rebuilding that kernel, but I will put it up into the testing area
when it's done so you can see if it helps or not.
