USB drives not showing up in Windows Explorer

[Chris Craig]

For some time, when I connect my external USB devices,
they will show up as a drive icon in Win Explorer, but
without a drive letter or volume titles. Now, the problem
has progressed to the point where the above happens, but
then almost immediately they disapear, yet I can use other
pograms to connect to their known drive letters.

Any ideas?

Check Removable Storage under Computer Management (Right click on My
Computer and Click Manage).

Try removing them from Device Manager (Click Start-Run-Type devmgmt.msc
and click OK). Then try this:
Open regedit and navigate to HKLM-System-CCS-Enum-USB

Now find your USB Flash drive and delete the Vid_Xxxx folder that it
exists under. Now reboot after you have done this and see if that fixes
anything.
