I upgraded my Ubuntu machine to 10.10, and I'm having an issue with bluetooth dongle now. The issue is: dongle will not properly load on boot. What I have to do to make it work is unplug, then plug back.
aside from the question "wtfigo, how to fix that?", I would like to learn if there is an easy way to programmatically disable USB port, then enable it back; make it equivalent to "plug out, plug in" action. I made a quick look at ubuntu utilities, couldn't find the one which would let me disable a single USB port
