win7 usb mass storage device not working

i have a 2.5 inch external HD in an enclosure and the drive works on every sytem i plug it into exept for my win7 box at the office. When i plug it in (and i am trying the usbs on my monitor/keyboard/front of pc/back of pc) it says unrecognized device and the device manager says:
Windows has stopped this device because it has reported problems. (Code 43)

and when i try to update drivers it says its up to date. I have tried ninstalling it and re-scanning for hardware changes but no luck. Why is it working on all my other machines but this one?

any ideas or suggestions?

very interesting ... looks like were making progress. So i unplugged everything, restarted and when i plugged everything back in it said, software has been installed and device is ready to use. However, when i go into the device manager, all drivers are installed but when i go to disk management or my computer, i only see my primary HD and my opticle, but no additional drives ... no external.

So ive gotten farther but not there just yet. any other suggestions?

you dont see the device at all in disk management? Normally i would stay change the drive letter of the drive in disk management because it wasnt showing up in "my computer".. odd
have you tried another reboot? try changing the drive letter of that optical drive as well followed with a reboot if it doesnt show after that. Since the enclosure does install, try a different usb port in the mix as well :) we are gettin there

i restarted and no change ... so i unplugged the external, changed the drive letter of my optical, restarted again. Plugged in the external into same port and nothing, not even a pop up that the device was or wasnt installed. So i unplugged the drive and plugged it into another USB slot and again, no messages bad or good. still nothing in disk management and no warnings or errors in my device manager. So i restarted again without unplugging it and still no luck.
so i plugged it into another pc running fedora12 and got zip also ... then i plugged it back into my pc and it came up! WHAT? wtf is going on ... so now it works on my pc and im currently rnning some diags on my disk (external)

can anyone explain to me what is going on?

I don't know that this will help much, but you can also try going into device manager and everything under usb controllers and let them all reinstall when the drive is plugged in
