Anyone have any luck with using MyWi 7 with windows 8.1 Pro (bootcamp)?? Specifically, the USB tethering? itunes is updated, 64-bit version. iPhone 5s, 7.0.4 Phone is recognized by iTunes, no problem there. It was working before, and I don't have any idea why it isn't now. A windows update maybe?? It works fine while in OSX.
