USB port on the nRF52 board

[wez]

Is this just for powering and flashing the device, or can it be accessed as a peripheral by code running on the device?

The application I have in mind would implement a USB HID as well as a BLE HID and I'm wondering about the best way to implement this with this new board.

I'm afraid it won't work.

The nRF52 doesn't handle USB internally like the microcontrollers in the Feather 32u4 or M0. It uses a CP2104 USB-to-Serial converter like the ESP8266. The CP2104 will only register with the USB host as a Serial device.

Related to this, and I didn't think it warranted a new thread :

What can I use for a USB host that will hook up to the nRF52?

I don't know of anything specific. You could probably use a Feather M0, since that microcontroller handles USB internally and is capable of acting as a host.

You aren't likely to find anything of a simple plug-and-go variety though. USB is a fairly complicated protocol.
