Windows 8.1 OEM causing problems with audio interface. Want to downgrade to 7.

My pro audio card (focusrite scarlet 8i6) has weird issues with Windows 8. It will drop out completely and lose its usb connection, crashing my DAW and ruining workflow. Ive wrestled with it for months now and I'm done with it. The card works great with my older laptop running 7. I've updated all related drivers, updated windows completely, and recreated the issue in several different audio applications.

My issue is that the drivers for the laptop itself , on the Asus website, only list 8 and 10 versions. Am I out of luck to get this laptop running decently on W7? It's an Asus R554LA.
