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.

Are you using that Belkin hub with midi?

Maybe my problems have something to do with the combination of makes & models, but after some research I couldn't find any differences in hub specs. The one I bought was a Techgear powerd hub. The problem was, if a midi device was plugged in, some notes would intermitantly stick and when I put the qwerty/mouse in it would intermitantly select random things.

As far things heating up, I'm sure this has happened a couple of times when I first powered up.

The cables are all in practically new condition and never really get moved, but I suppose there still could be a short.

Any experiences with a USB hub for midi devices using a similar system?

Anyone know if there is any difference between front & back usb ports? I assume the extra port on the back of the qwerty is less capable because it shares with the qwerty/mouse.

Every device on a USB bus, when it initializes, tells the host how much current it expects to draw from the bus.

Does this happen each time the computer is turned on?

Thanks for the advice guys.
