Please read problem, I've tried simple solutions without success!

I bought USB flash drive thinking my pc was 2.0 capable. PC was not 2.0
capable (older machine) so I bought and installed 2.0 pci card. The drivers
for the PCI card were installed, then the card was physically installed, but
it did not act as a pnp device... I had to manually associate the drivers to
the card to get it operating. Most 2.0 compliant devices were recognized by
PC and automatically shifted to
the higher standard, but the USB flash drive still remained unusable (PC
would give it a drive designation, but would not see stored files on flash
drive and would not allow files to be stored there). I tried uninstalling
flash drive, removing some files from registry per sandisk website, but
nothing worked. In my infinite wisdom I thought that maybe if I associated
the drivers for the 2.0 pci card to the flash drive it might somehow get it
to operate as a 2.0 device. HUGE MISTAKE! I assigned a driver (Nehcd.inf)
to the sandisk usb flash drive. Now whenever I plug the flash drive in I
get the blue screen of death immediately! It reads that windows is shutting
down to save my machine from
damage, yada, yada, yada, and then list this line of text:

Stop: 0x0000007e, (0xc000005, 0xf88ce80d, 0xf8a08774, 0xf8z08470)

NEHCD.Sys Address F3D1480D base at F3D13000, Date stamp 3bfc0082

I should have remvoved flash device and used device manager to assign the
former driver to the device, but in my panic I removed the device from the
device manager. Now there is no way to get the device showing in device
manager because whenever I plug it in I get the blue screen. I've tried
using a restore point in system restore but it did not work. I tried using
my last good configuration from the start up but that didn't work either.

Is there a way to manually assign a driver to the usb flash driver without
using device manager? I see the "NEHCD.Sys" in the second line of the error,
is there something that can be done in the config.sys files to correct this??
I need to get this driver to quit associating to my usb flash drive.

Thanks for time.
