Usb Over Current Message?, Why am I getting this message? Options

[pushtobreak]

Anyone else ever get this message? It seems to be getting worse or maybe it's just bugging me more. I've only got a Logic7 dongle, a Motu fastlane midi interface and the qwerty/mouse plugged in. I thought it was the UC33 controller, but I'm still getting the message without it plugged in. I'm getting more ram soon could that be it?

I tried a USB hub to try recofiguring things. I was actually hoping to use another USB device. The hub didn't work at all. I did tons of research and found there have been some problems with hubs and macs. My problem was unpredictable behavior from the device(s) plugged into the hub. Now I just want to get to the bottom of the original problem, but if anyone has any advice about USB hubs I'd appreciate it.
The "USB overcurrent" message usually comes up after the computers been on for a bit, but usually not when I'm even using anything other than the qwerty/mouse. If I power down it usually solves the problem for a while.

Every device on a USB bus, when it initializes, tells the host how much current it expects to draw from the bus. Something on the bus is drawing more juice than it is supposed to. The first thing I'd do is check all my cables and connectors. Flex everything back and forth and see if maybe there is a cable somewhere that has an intermittent short.

Failing that, you want to get a line-powered (not bus-powered) hub. I have a Belkin 5-port hub that works pretty well. Plug each thing into a different port. If you have a device that is drawing excess current, that might help isolate it.
