In the meanwhile, I tried reformatting the stick. I got the "Open File /
Optimize Memory" option window briefly before the Windows found new hardware"
window opened.

Re-plugging it, I get []? Other devices

( [] represents the icon, also in the tray, Found New Hardware)

Device status This device is not configured correctly (Code 1)

(No changes, nor links to the device under:
1. Under Disk Drives

3. Under Universal Serial Bus controllers as a USB Mass Storage
Device)

USB HS-SD
USB HS-xD/SM
... USB Device (under Disk Drives)
and ... Card (under Devices, except the last, "USB

partenope,

Plug in the memory stick and look in Device Manager to see how it is
recognized there. Device Manager should show the device three times, as
follows:

1. Under Disk Drives
2. Under Portable Devices
3. Under Universal Serial Bus controllers as a USB Mass Storage Device

Note any indication of errors, such as a yellow bang (!), or any other
indication of a problem. In Device Manager, follow any any suggestions for
resolving any problem indicated. Post back on results.

freddy and all,

I installed a PNY OPTIMA Attache' 2 gig memory stick. My upgraded (Vista
Home to Vista Ultimate) Dell lost the connect.

I tried finding drivers on re-install in C:\Windows (and subfolders).

I found a reference to wpdfs.inf in the registry, but the only occurrence of
THAT that I find is a zero byte file, " Mstf_User_WpdFs....... " in
C:\$INPLACE.~TR\yada...yada..yada

I have deleted INFCACHE.1 file and get no recognition.

I assume I have a "lost driver." Anyone have any ideas? I can't get any
memory sticks to work in the machine.

Thanks for any assistence.
