Alright I've run out of options. I purchased a kkl from ECS tunings website because I've read on here about all the problems people have run into buying cables off eBay.  So far I've had 0 luck trying to get this cable to work and it's been almost a week now. I tried the drivers that are given with the cable to no avail. Uninstalled everything and reinstalled numerous times. Will anyone help me get this thing working and I'll compensate you for your time?

Take it apart. Most likely has a CH chip inside... trust me I had the same issue. Got an MPPS today, hopefully it works.

But yes also look in device manager, that will atleast give some info about it. You can check ID of it if it shows up atleast in properties.
