Flashed to NRD90U... Noticing the same thing here now: Device isn't detected automatically after reboot. Going to connect up a keedox hub to see if that fixes it, as it did with build122-b1.

Flashed, and connected up via USB 3.0 hub -> USB 3.0 host port. Let us know if you want to test a different flavor of things, we can pretty easily re-configure it now.

Yep, it looks like the phone is having an easier time talking to the host, thanks.

(It's complaining about protocol faults now though, but that's bug 626654)
