64 Bit found new hardware--but it's not

I have four USB hard drives that I regularly use to back up my WinXP fully

updated computer. Suddenly, Windows stopped recognizing the drives. It says

it's found new hardware--a USB device--and wants to me to use a Wizard to

install it. I've canceled the installation each time, since Windows has

always recognized my USB external drives before.



I've been plugging these drives into a seven-port Kensington USB hub. When

Windows wouldn't recognize the drives, I tried plugging one into the USB

port on the front of my computer. Windows seemed to recognize the drive

there but first said there were faster ports it could be plugged into and

then started making the sound of connecting and disconnecting, over and

over.



I tried shutting down and restarting the computer no change. I tried

unplugging the hub and plugging it back in Windows recognized that device.

But still, when I try to plug in any of my USB drives, they don't work.



Any idea of what's wrong and what I can do about it?



Thank you!

Have you tested the ports on the back with a drive directly ?



Have you plugged the Kensington into a port on the back, then

plugged a drive into the Kensington ? Does that work ?



Perhaps the front ports are marginal (poor signal quality,

preventing reliable operation).

If all else fails, and you've given up hope, then

visit this page. If some registry entry for the USB

devices is screwed up, flushing the whole works and

having WinXP build it up again may work.

Thank you, Paul! I did something else this morning, and it worked--but I

don't know why.



I had been away for a few days and had turned off the printer from its

powerstrip. (It's on a powerstrip separate from that for the computer

because it can't be plugged into my UPS.) I didn't realize at the time that

something else is also plugged into that strip--and right now I'm not sure

what that other thing is.



Anyway, this morning I turned on the printer's powerstrip, and it occurred

to me to try the USB drive again. I plugged it into the USB hub, and now it

is recognized and works fine.



I'll try to figure out later today what other thing is plugged into the

printer's powerstrip, but I still can't figure out why plugging directly

into the computer didn't work.



I'll definitely keep your instructions for future reference.



Thank you again!
