PNEV7462C USB Descriptor problem

Dear,

 

I have recently bought the PNEV7462C eval kit and try to get the Cockpit to work. Tried to reprogram the firmware that came with the cockpit program using the DownLoad option.

 

If I drop the firmware CRD_00.bin on the the mass storage device it will disconnect, reconnect and give status code 0 in return. Seems to be so far so good. Same for the .dat file.

 

Now if I reset and wait for the device to connect to windows (10) it comes back with an error that the USB descriptor cannot be read back and nothing happens...

 

Also the VCOM driver installed again, restarted, uninstalled, restarted, reinstalled, tried again, etc. We are an hour or two further in wasted time and it still doesn't work.

 

So what could be the problem?

 

Regards,

 

Roland
