I am an Administrator but was unable to delete the file. Allowed the re-boot to proceed and, voila, all the unknown devices are back!

I tried deleting the INFCACHE.1 file several times, even re-booting in between. I only have one user account on my machine - Me, Administrator. I'm assuming it's the file behind restoration of all the Unknown Devices.

I am not sure I follow were you successful in deleting it? did it work? And yes it is
In case its my bad; here is the full list;
  1. Find and then right click on the file named INFCACHE.1.
  2. Select Properties.
  3. Click on the Security tab.
  4. Click on Edit to edit the permissions of the file.
  5. Click on Add to add User Groups.
  6. Type Administrators in the User Groups field and click on OK.
  7. Set Administrators to Full Control and click on OK.
  8. Move or delete the file INFCACHE.1.
  9. Reinstall a device to force Windows to rebuild the INFCACHE.1 file (DO NOT reinstall the same external hard drive that you were having issues detecting before. Please connect another USB device other than the one that Seven had an issue detecting).
You might have to do this several times

No, I wasn't able to delete it. But your steps to alter permissions will help I'm sure. Still a bit of a novice, I'm afraid, when it comes to dealing with Windows Security. e.g. when is an Administrator not an Administrator???

No worry I'm still trying to get this USB thing perfected
When windows decides otherwise I have tried to find an explanation as I don't know the answer but all I find are ways to change the permissions sorree

By default your user account will be a member of the administrators "GROUP" but you will still be restricted by Windows 7 UAC settings. One of the main differences between Windows 7 built in hidden Administrator account and your user account is the actual Administrator account doesn't have to contend with UAC. Its disabled when you log in with hidden admin account. You could temporarily turn UAC off while you try to sort this out. Then turn it back on to the default setting again when your done. It may make things easier.

This sounds interesting. But, how do I access the "hidden admin account"? When I look at the User Accounts, all I see are myself and the "Guest" account (which is disabled).

The built in administrator account is disabled and hidden by default. You have to enable it before you can access it or use it.
Built-in Administrator Account - Enable or Disable[2]=User Accounts
Turning UAC off is a lot easier though and should accomplish the same thing.

Logitech likes to "call home" (extra protocals). Anti-virus/and or firewall could possibly stop the outgoing call. backweb-8876480.exe

"backweb-8876480.exe" is installed with the software for Logitech products. It checks for software upgrades from Logitech.
It's present under Software => Logitech Desktop Manager, where it can be uninstalled

Well, the good news is that my new Logitech mouse is now working. The bad news is that I had to re-install Windows.
I attempted to add Administrators to the Properties/Security setting for INFCACHE.1 but couldn't get beyond the spinning blue wheel, no matter how long I waited. I did manage to delete the file by changing my own access to "Full control". Then the fun began. Deleted all the "unknown devices" and re-booted only to lose my (PS/2) mouse control. Using Safe Mode and Restore, got control back and repeated cleanup steps. Lost track of all the variations of what went wrong over the course of the next hour or so but eventually ended up with no mouse and no KB control whatsoever, not even in Safe Mode. Nothing left to do at that point but insert the Windows install disk and start over from scratch.
Thanks to everyone for all your help and suggestions. It's been a true learning experience.
