Micromod USB not recognized

Tried 2x computers, 2x USB cables and 2x other system boards - Micromod will not show up. Must be doing something wrong?? LEDs on - not much else working?

Setup is micromod single with SMT32 and LoRa.

All help would be appreciated :oops:

Run through the steps here https://learn.sparkfun.com/tutorials/mi … rogramming, including installing STMCube and complete the DFU bootloader section and see how it goes

Not so much

Do you have a linux or windows PC to test against to rule out OSx issues?
