Hi,

 

I'm using a fx3 and when I connect my board to the pc I have the following error in the device manager : Unkown USB Device (Device Descriptor Request Failed), I have absolutely no idea how to deal with this, installing the drivers for windows10 didn't help. Any insight would be appreciated.

 

Thanks,

Adrien

It can be either that you have modified the FX3 descripots (or the driver files). Please use one of the default firmware like bulkloopauto and check. Also, please bind to the defaut FX3 drivers that are available on the web. Please avoid any changes that have been made by you.
