USB memory stick "Unknown device" on two XP machines, but fine on a third...

[Noozer]

I have a new 1gig OCZ Rally USB memory stick. It's not working properly and
I'm hoping for some help...

Plugged it into my Windows MCE 2005 PC earlier today. It installed fine and
I copied a number of files to it. When I was done, I ejected the drive.
Walked over to my main Windows XP Pro SP2 machine and plugged it in. LED on
the drive lights up, Windows complains that the USB device is not recognized
and the LED goes off.

So, I pull the drive out, go back to my MCE 2005 PC and plug it back in. LED
lights up, Windows complains that it's not recognized, LED goes out. The
drive worked fine here 5 minutes earlier. In device manager on both PC's it
just shows up under USB Controllers as an Unknown device.

So, I'm writing an RMA message to OCZ as the drive has obviously failed...
but before I hit SEND, I take the drive upstairs and stick it into my old
laptop with 1.1 USB ports. Windows XP Pro recognizes and installs the drive
fine. All my previously copied files are there and I can move them back and
forth.

I bring the stick back to my PC - no luck. The MCE machine - no luck.

So, the drive DOES work, but not on these two machines...

WHAT is going ON?!?!?!

Hi Noozer:
I just purchased a PNY 1 Gig drive and very similar
problems; one machine no problem but identical error messages as you receive
on the other machine. Mine will work only on 2.0 USB. even when correct
drivers installed refuses the 1.1. Decided to check on another problem as
remote assistance on the xp pro machine does not recognize that I have
Messenger running, frankly very tired of Windows so will be picking up a
copy of Linux shortly from a buddy. Good luck Noozer
