No USB on Windows PC Odrive 3.6 24V, DFU is working

I have 2 Odrive Boards V3.6 24V. Both boards are not recognized by Windows via USB, no USB device can be seen in the device manager.
Then i flashed a new firmware (“ODriveFirmware_v3.6-24V.hex”) via DFU, which worked without problems.
After that I switched the switch back to “Run”, but nothing has changed.

The problem is solved, it was a problem with the power supply that could not supply enough power when the board started up. As a result, the board or the ARM did not start up properly.
Strangely, the DFU mode worked.
