Windows 7: USB Device Not Recognized

USB Device Not Recognized

Hi guys!!

I've been meaning to ask some help regarding the issue that I am having however I was reluctant because of the fact that I fix computers for a living(I'm not that good at it though..).

I need help!!

I've been getting "USB device not recognized". I got the issue after purchasing a new power supply. I think my motherboard is fried. But I need your opinion guys. Here are the things that I did.

- went to device manager and uninstalled everything under USB controllers
- dismantled my computer to the very last piece and put everything back after an hour of waiting. (i made sure that the power was drained)
- put back my old power supply thinking that the new PSU that I bought was damaged

When I plug it in, it just says "USB device not recognized". I tried plugging my usb to a different computer and it was not working anymore. I did a little experiment and tried a good USB device on another computer. It worked well, for sure. I plugged it in mine, it said "USB device not recognized". Plugged it back in the computer that detected it earlier and BAM! It won't detect it anymore. Power surge I guess??? I am not sure...

Please Please Please.. I need your help on this guys..

1. Is my motherboard fried?
2. Is there a way for me to fix the devices that I plugged in my computer?

Many Thanks!!!

I called the local techs here and they're willing to fix my external drive for $20.. Is that price reasonable?

USB device not recognized - but there is no usb device connected
It's recognized in device manager as "Unknown device". But I've not connected anything to pc. Also all of my usb ports are working at 1.1 speed. When I try to connect any device, I get the message "that it could work faster, if i connect it to hi-speed usb port". Any suggestions?
