Currently using a Toshiba Satellite a665-s6070 laptop with Windows 7 Home Premium. I had an optical mouse and an iPod Touch plugged into my usb ports. I picked up my laptop to move it from my coffee table to my lap, and I received an error that said "Power Surge On Hub Port: A USB device has exceeded the power limits of its hub port." My ports were unresponsive after that. My iPod Touch still works fine, so I know my peripherals weren't fried. I rebooted my machine, still no response--no power to the mouse or a flash drive, nothing. I checked device manager, and it still lists the USB ports as functional. I looked around on MS Answers, and followed instructions to uninstall the USB controllers in device manager, reboot my machine, and allow the controllers to reinstall themselves, which they did automatically. Same deal--showing up in device manager as functional, but still no power to peripherals. Microsoft Automated Troubleshooting Services found nothing wrong. Rebooted again, just for kicks. No change.
I've copied and pasted the results of the PC Diagnostic Tool. Hope it's some help.

Thanks again!
EDIT: I forgot to mention--I bought this computer brand new from a retail chain only three weeks ago. Don't know if that's important.
