@kapaggar: Huh. Guess they sprung a new diags rootfs/menu on us. (And that it supports adb is new, hence @knc1's surprise, we're used to USBNet & dropbear

).
For the record, you don't have any issues exiting from diags and restarting into the main system?
And is there actually a menu mentioning USBNet and/or SSH?
Once you've made proper dumps of all this, I'd sure be glad to take a look at it...
