I have been activating the USB modem mode using the diagnostics code for the Samsung focus. Anyone found any drivers for the USB modem mode? Im using Windows 8 and all downloads I have tried are for Windows 7. I really want to tether via USB as I can avoid the battery drain associated with Wireless Internet Sharing! Cant seem to find anything on the Qualcom developer site either.

As far as I know USB tethering isn't possible on WP 8. You can still use WiFi tethering and connect your phone via USB to charge the phone while you are tethered.

You're in luck: I found the drivers you need just yesterday. You'll need to manually install them using Device Manager, and only two of the drivers (modem and diagnostics port) are covered, but that's all you need.

Link to the post with the drivers, and to another post on XDA-Devs where I explained the full process:
