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.... Steven P. Ulrick
