I wonder if there is a USB2 to USB3 adapter? but the problem is you have to run the drivers update like Boot Camp 5 off the hard drive, and that is easy and how I do it, copy or download in Windows and to Windows folder is all so the USB device is not ejected or unmounted.
I have dual Windows 8.0 and 8.1 for now and prefer it over Windows 7 as much as I preferred 7 over Vista.
8.1 makes it easy, wait for its release 10.17
turn off / disable / set to boot to desktop - and don't sweat if you do open or get into a Metro screen which feels like being lost. As for having to have an MS Live.com or Outlook email and use that for logins.... THAT bothers me more than Metro.
