Sure you did #17 as explained in post?
normalboot.reg and safeboot.reg are identical!! (Both fine)

command prompt:

Code:

net  use

anything listed? If not:

Create a new user account (as a test). Logon under that account. Same problem?

Detach the usb stick(or usb drive)
Save attachment somewhere. Double click the saved file. Imports succesfully?
Attach usb device again. Does it have a drive a letter now? Can you change it?

In Elevated Command Prompt

Code:

 
reg  query  HKLM\Software\Microsoft\Windows\CurrentVersion\Policies\explorer

Post output

Run REGEDIT and browse to HKLM\SYSTEM\MountedDevices
In the right pane you see a this (and much more):

#{7e130408-d361-11e2-8060-0025d3b22ded}
#{7e130409-d361-11e2-8060-0025d3b22ded}

Click on the first and press DEL-button. Do the same for the second value. Press F5 to refresh. Does right pane change?
Now try to assign a drive letter.

Switch back to regedit and press F5 (refresh). Does right pane contents change?
detach usb drive. attach us drive. Switch to regedit and press F5. right pane does change?

Hi dave (OP),

Did those drives EVER work properly with that OS as installed now?

What was done to that system, just before it stopped working properly, best you can recall....?

Thought about it longer, my suspect is:

SOUTHBRIDGE issue (chipset), just the driver hopefully.

Here's your spot for it's downloads:

Maybe your INF cache (drivers) is hosed also, I noticed this thread on the subject:

Why aren't my USB Device Divers not working on my laptop?
