Ah please help!!!!

Will somone please help me I have windows Xp and have been using homebrew on my PSP for a long time, but recently my computer won't connect to my PSP any more it just says " USB device not recognized " and it says a little something about a malfunction, but I don't understand because my memory stick isn't corrupt and the PSP is just fine too, and the worst thing is I had it plugged in working great, I unplug it plug it back in and its done for. So if anyone can help I would greatly appreciate it.

Hmm.. Maybe you should try getting another USb cable.

Never mind I found out that the USB hub I was using, was completely fried. Well that sucks thanks anyways, see you guys later I've got to go fry the other three. :D
