I cannot make Development Desktop 2.1 connect to app3.0 board.
The board turns up in device manager as a USB device
DD2.1 tries to connect
but then gives up
Iv'e tried to update fw without luck - I only get an error stating "No DFU capable USB device available":
PS C:\COINES\v2.8.8\firmware\app3.0\coines_bridge> .\update_coines_bridge_flash_fw.bat

Press any key to continue . . .
The problem is the same no matter if I connect my BMM350 module or not.
What can I be missing?
