Hello,
I received today a moduknob, and I attempted the firmware upgrade following your updated guide.
The hex file upgrade went ok but once I reconnected the usb cable to the moduknob nothing happens.
If I press the button to boot in programming mode, the device works so I can access it with the STMCube program, but it is not working normally as controller.
Windows is not detecting it as a device that has been connected.
Thanks for your support.
