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.

harmonp,

Some folks have had good luck resolving issues like you have by deleting the
INFCACHE.1 file, which can get corrupted with bad data and cause issues. The
file is located at C:\Windows\inf. There, scroll down to the INFCACHE.1 file
and right click it and select delete. To do this, you will likely have to
give yourself permission to delete it, because of Windows built-in security
you know. Just right click the file, select Properties and then click on the
security tab. Let us know whether this procedure does anything. Sometimes
it does and sometimes not.

Why is it that Vista can't hang on to drivers that have been successfully
installed. I have an HP laser printer and an HP All-in-One. Both have Vista
drivers which have been installed and both work correctly...for a while.
Periodically, Vista says it needs to look for new drivers, then it can't find
the drivers, and I'm tied up for hours trying to get Vista to recognize one
printer or the other. Sometimes Vista (Ultimate) loses track of the USB
printer drivers and sometimes it is the Scanner driver. I had to buy all new
printers/scanner to work with Vista, and yet I have to spend hours keeping
them connected properly in Vista.
