Hi guys - I'm not the sharpest knife in the kitchen when it comes to finding the right drivers for my hardware, but since my Windows 7 clean install, I haven't been able to use my two USB 3.0 ports on my L501x. I've tried installing what appear to be the drivers from the support site - they unzip and install, but absolutely nothing happens, and I'm still left with unrecognized USB controllers in my device manager. Can anyone assist?
