On an Intel iMac (Model MB324LL/A) (currently running 10.6.4), every few minutes (or seconds) I get a Finder popup window reading:
Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled.
In Console, the associated message:
USB Notificaton: The device "EHCI Root Hub Simulation" @ 0xfa000000 has caused an overcurrent condition. The hub it is attached to has been disabled.
What I want: a way to prevent these messages from showing up in the Finder. Any solution that prevents or reduces the annoyance would be most appreciated.
For reference: this occurs with our without USB devices plugged in, with any boot disk I've tried. I've reset the SMC and the PRAM. I assume it's the motherboard, and I'm simply looking for the cheapest way to make this a usable paper-writing, web-browsing beast of burden.
Thanks!
