Computer USB Headsets: Required Driver List

What drivers are required for my computer USB headset to work with my computer?
The drivers your Plantronics USB headset requires should load automatically when you plug the headset into your computer - no software is necessary. The drivers, which are native to the Windows operating system, are as follows:
  • C:\WINDOWS\system32\drivers\drmk.sys
  • C:\WINDOWS\system32\drivers\portcls.sys
  • C:\WINDOWS\system32\drivers\USBAUDIO.sys
  • C:\WINDOWS\system32\SysFxUl.dll
  • C:\WINDOWS\system32\WMALFXGFXDSP.dll
If you are missing one or more of these files, check your Windows installation CD or your computer manufacturer's web site, and then save to the proper folder.
