I think I have it right that the problem was solved by clearing the driver.cache -

The infcache.1 is used to store information about USB drivers the information in this file may have become corrupted or may cause windows to load the wrong driver or cause a driver not found message to be generated.
Deleting this file will force windows to generate a new infcache.1 file


which is what I thought - incorrectly - of course I now know could be addressed by my post 57 and was the line I working on in my post 55
as I had read about stored usb drivers causing the problem.

If it is that, then would system file check address that issue.

However and whatever as Troy said - CompCav - brilliant.

Not brilliant it was the cache plus replacing usbstor.inf

The file was the right size but it was not a text file when I opened it in notepad it looked like several rows of rectangles next to one another.

Thanks again for the help, all of you!

I don't think anybody answered your question:

When I click show hidden devices, the screen refreshes and under Non-plug and play Drivers there are two items with yellow ?'s

MpKsla9df559d
MpKslcb4f820d


While I am in here deleting should I do something with these?



These are leftover MSSE update drivers. MSSE installs a new driver with every update. It is supposed to remove the old ones but supposedly there was a bug in the earlier versions so it didn't always happen. The MS folk tell me they have fixed the problem but I don't think they went back and had it delete the old ones.

Here is an example from an old OTL log showing both a good driver and a bad driver:

DRV - (MpKslb0210cf6) -- File not found
DRV - (MpKsld2c62d31) -- c:\Documents and Settings\All Users.WINDOWS\Application Data\Microsoft\Microsoft Antimalware\Definition Updates\{0C5E2617-C252-4B56-B611-7F3A15EE5358}\MpKsld2c62d31.sys (Microsoft Corporation)


If there is no corresponding .sys file then they can be removed.
