  USB over current change on boot         


Author: Mark Healey
Date: Jul 5, 2008 23:14

When I boot I'm getting a "USB over current change" error on hub 1 both
ports and the ports don't work.

I disconnected everything from those ports and rebooted and got the same
message.

I was attaching and removing a bunch of things earlier, including a
powered USB hub, so It is possible I smoked something, I suppose.

Several questions.

Since everything is disconnected I'm assuming that some kind of fuse or
breaker went. Is there somewhere I could look for such a thing to
replace or reset?

Could it be the power supply?

Could I have somehow applied too much current internally and caused
something to short?

I opened the VDU to clean it, and couldn't see the relay
clicking. When it's 'lost charge' I might try to just 'on-lock'
the relay if that's possible.
