Delete UpperFilters and LowerFilters Registry values

The first thing you need to do in the Registry is to delete the UpperFilters and LowerFilters Registry values. Registry values are listed under Registry Keys and these values contain instructions for your Windows installation. You should take a backup of your system and Registry file before making any changes.

As a brief explanation, UpperFilters go between the Operating System and the relevant Driver, and LowerFilters go between the Driver and the relevant hardware (such as CD-ROM drive). These problems are usually associated with DVD and CD-ROM Drives.

Select Start > (in Windows XP then select Run)
In the Search box (or Run box in XP) type in regedit and click OK
In the Registry Editor find the HKEY_LOCAL_MACHINE folder under My Computer and click the + icon to expand
Using the + icon to expand folders, scroll to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Contro l\Class
Under this folder you should see a series of subkeys which are 32 digits in length
Use the GUID Subkeys list below to ascertain which Global Unique Identifiers (GUID’s) relate to your problem
Once you have found the GUID relating to the problem device, click the registry subkey corresponding to this GUID
You can now locate the UpperFilters and LowerFilters values in the window on the right (you may only see one of these)
Right Click on UpperFilters and select to Delete
Choose Yes to the prompt “Deleting certain registry values could cause system instability. Are you sure you want to permanently delete this value?”
Do the same as above for LowerFilters (ignore any values with .bak extension)
Close Registry Editor and restart your computer

Thanks for the update DeVeX and glad to hear you could find a solution.

We might need to see if anybody else runs into this, but I have the G750JW with 208 bios and don't see any USB related errors in device manager, so hoping it will not be a common issue people see.
I've also upgraded to Win8.1 from the ASUS Win8 image if it matters, but don't believe there were any problems using Win8 either (just curious if it could be related to using Win7 at all or if some software change was made at the same time as the bios update?).
