Hi,
It would be great if anyone has an idea what kind of problem I am dealing with here.
Two days ago, my USP ports just stopped working. I turned off my Toshiba Satellite A305-6829 (operating system Windows Vista Home Premium) in the evening, the next day I turned it back on, nothing.
I tried to connect my mouse and two different external hard drives, their light is on, so there is power, but the devices are not recognized.
In the device manager, it shows a yellow exclamation mark next to all the USB ports and under properties it says "Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19)".
I tried to uninstall the drivers and reinstall, it's still the same. I tried a system restore as well.
Is there anything else I can do? Is it likely to be a hardware problem? The laptop is only 4 months old and everything else works fine.
Thanks so much for any suggestions,
Luna

Yes I did. Nothing. Did a System restore as well, no changes.

Unfortunately this didn't work either. I am at a loss what else to do, apart from completely reinstalling my system which would be a real hassle...

Are you up to date on all Windows Updates including SP1?
