Why my DSO Nano can not be recognized by PC

1 . Make sure you have installed the STM32 Driver.
2 . If your DSO can be seen by PC but shows as a unknown device , please remove the D2 ESP diode, then try again.
3 . If there’s nothing happened when USB pluged in, please check the R24 of DSO , it might be a 1.8K(182) resistor, you can try use a smaller one to replace it.
