Hi, I bought a Satellite L50D-B-151 laptop in last November, but try as I might, I just can't get on with windows 8.1(64bit)!

So to make the laptop "usable" I have installed Windows 7 64bit, and thanks to Toshiba, everything installed 1st time ...
and the system is working fine, except, the only thing that wont install are the USB drivers!

There must be some reason for this as I have spent 3 days trying to find any reason why the (Toshiba) supplied drivers for
this model, just will not install, what am I doing wrong?

Anybody .. Please!

Thanks in advance
