USB connectivity to PC

I upgraded to 7 from 6.3 and I'm having issues with usb. When I connect D1 to pc I don't get notification for debugging at all. I checked all settings and try to uncheck them reboot and check them again. I got nothing. I went back to 6.3 and USB works as suppose to. I did wipe everything before installing 7.0

Any ideas?

Thanks

what are you using for recovery?
rzr is what i used after trying with clockwork, did a double wipe all, and wipe cache twice, and the usb starting to work again.

Just an update USB connectivity is back after 7.1 install.
