External HDD help!

[BScott1122]

My coolermaster cases front USB ports recently stopped working. So, i bought a silvestone front panel with four usb ports mic/headphone and a 1394 (firewire) port. Before installing this my WD passport drive worked fine. However now, when i plug it in i get USB device not recognized. So, i figured maybe it was something with not enough mA going to the usb ports? So i uplugged my new front panel so all i had were the USB ports directly on my mobo. (all of which i kno work fine). i restarted the comp and plugged the drive into the back. i got the same message. So, now i dont understand what is going on. Its a fairly new drive too. There are no drivers for WD passports so i dont know what to do. i looked is disk managment and its not recognized. in device manager is unknown device. Please help!

1000W Cooler master PSU
Core 2 Duo E6850 @ 3ghz
