This week we plan to purchase a number of nRF52840 DK development kits. The plan is to use pairs of boards for assessment purposes.
The idea is one board will act as a USB dongle, which will receive wireless data from a second device (another Nordic nRF5280) and send the received USB HID data to a computer.
The board has a USB connector which connects directly to the nRF device, so I assume this board can be used as a USB HID dongle.
The Nordic SDK has USB HID Composite, Generic sample code, so I am hoping my assumption is true.
Just to confirm my question:-
Using nRF USB connector on the development board, is it possible for it to act as a USB HID device, for sending mouse, keyboard reports etc... to a PC?
Yep, I've put together a few nRF52840 devices that use USB HID - works great. Obviously (?) if you use the on board programmer/debugger you just have to have to switch your cable to the nRF USB port…

Obviously (?) if you use the on board programmer/debugger you just have to have to switch your cable to the nRF USB port after programming (or use two cables) or just use a J-Link and then you can leave the nRF USB plugged in.
Just like you figured.
The plan is to have both USB connectors connected, one for debug, and the other for the USB HID.
Operation of the board is confirmed!
Thank you for the support.
Time to verify the answer, then!
I would like to verify the answer, however unlike your screen shot, I don't seem to have a verify answer option.
I find I have to ctrl + F5 a few times to get everything to load correctly.
No luck with Chrome, Firefox, Edge...( or refresh)
The page looks fine. There are reply, mute, report abuse etc... options.
