Hello, Again

All of these items are things that I tried to run relating to USB2 devices.  
As most of you know, "D" means the following (quoted from "man ps"):
"D    Uninterruptible sleep (usually IO)"

I suspect that it is no coincedence that these USB2 related items are all in 
"Uninterruptible sleep"  This could at least somewhat explain why I need to 
reboot to get the use of our devices back.
On a side note, does anyone know of a way to kill the above processes, short 
of rebooting?  "kill -9 PID" does not touch them.

I am attempting to build a kernel from kernel.org right now.  Even if that 
won't build, I will need to reboot soon to at least get rid of these 
"unkillable" processes.  I bet that when I do, all of my devices will be 
functional....
