Don't restore yet. Try uninstalling the USB devices again and reboot. See if that helps.
Uninstalled again and restarted, waited until all drivers were reinstalled.
Entire usb category is still called unknown (with question marks on every item).
For comparison, I also uninstalled Storage controller JMicron JMB36X, which reinstalled fine and appeared as normal under storage controllers category (no question marks or yellow flags).

Appears to me that the usb.inf and usbport.inf file are correct and that is where the deviceIDs are associated with names.

Above from usbport.inf
INF files are however not used directly. Instead they are compiled into .PNF files. I suppose the .PNF file could be corrupt so let's try deleting usb.PNF and usbport.PNF and also unknown.PNF. They will be recompiled the next time the files are used so also uninstall the usb devices again. Then reboot.
Member
I deleted the three PNF files this time (but I assume you didnt want me to delete the inf files, so I left those).
Uninstalled the USB drivers.
Restarted & let them reinstall.
Still showing under Unknown category.

Does
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}]
still look the same as your last post?
Could I see a screen shot of the device manager with the unknowns?

USB drivers look slightly re-ordered currently, since "36FC9E60-C465-11CF-8056-444553540000 V3.txt".
Here's the current version of the reg key V4:

Download the attached usb.zip file
and save it then right click and Extract All (to your desktop) then Extract. Right click on usb.reg and Merge. Reboot and then look to see if anything has changed in Device Manager.

This was the result:
System restore and importing/merging a regdit bkp I made before your reg file didn’t work.
Neither did uninstalling then reinstalling all remaining usb drivers.
I had to use an onscreen keyboard to type this. Thank god my mouse wasn’t plugged in via usb.
Malware Expert
Delete the reg key again. Then try merging your backup reg. A Merge does not remove key info that is not overwritten by the reg data. This last .reg file was from my Win 7 64 bit so alternatively you could try just deleting the lines that were in the .reg (right click and Edit to see it)
Member
Okay I deleted:
36FC9E60-C465-11CF-8056-444553540000
and the usb drivers are reinstalling again as question mark devices.
But when I tried to import my reg backup before this, my soundacards, audio drivers and devices in my audio control panel have disappeared.
Malware Expert
Is the backup a full registry or just for that one key we were working on?
Do you have any new unknowns in the device manager?

The registry is a full backup.
The # of unknowns are the same as yesterday.
Member
I uninstalled all the sound drivers in device manager and let them reinstall after scanning for hardware changes, and they've returned.
But I was concerned that it wouldn't allow me to system restore to the point before I merged your reg key.
so I tried restoring to an older backup that I made just before you asked me to downgrade my chipset.
The restore was successful and although I can undo it, I'm concerned that when I messed up the registry, other invisible problems may have occurred.
Would you like me to re-perform all the steps starting with the chipset downgrade until the point where I merged your reg key?
Malware Expert
No. Do you still see the same unknowns? What does the key look like now?

Same unknowns, same device manager unknowns as shown in my earlier post:

This is what I see on my win 7 64 bit:
That's what we tried to do with the merge.

Verify that you have a file:
c:\Windows\System32\SysClass.DLL
See if you can add the first three lines:
***************************************
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}]
"Class"="USB"
"ClassDesc"="@%SystemRoot%\\System32\\SysClass.Dll,-3025"
@="Universal Serial Bus controllers"
*******
Copy the text between the stars. Open notepad and paste it in. File Save As to your desktop "usb3.reg" OK
(Make sure you use the quotes or it will tack on a .txt)
right click on the file and Merge.
The @ is how they call out the (Default) entry. These would appear to be harmless labels so shouldn't cause any problems. Does that help with the unknowns?
To delete the above you just do:
***************************************
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{36FC9E60-C465-11CF-8056-444553540000}]
