I've seen this mentioned elsewhere on the thread but have not seen any answers. Running stock 4.2.2 plus the modified framework-res.apk on Nexus 7 3G.
Wireless hotspot works great. USB tethering does not. As others describe when clicking on USB tethering the phone re-establishes connection to Mac or Windows but the box doesn't stay clicked and no network connection becomes available. I've tried this with HorNDIS drivers. I agree with previous poster who said it didn't appear to be a driver issue since it stops working before that would come into play...
Maybe this can be useful to someone else. I added to the apk the mod to enable voice dialog. You can't actually use it as a cell phone, but you can configure a SIP account and call through data connection. It's most useful to me so I thought to share.
The mod source is here: http://forum.xda-developers.com/show....php?t=2025377
