ERROR: cannot communicate with the Proxmark

Hello Community,

I tried my new Proxmark3 on Windows 10 to get it working with ProxSpace.

In the end I finally managed to install a new bootrom and fullimage with pm3-flash-all. Then I would like to connect with the command pm3. It finds the port automatically and connects. Then I get an error message that communication is not working.

Then the device manager only shows my device under USB controller and that it would be an unknown device (error when requesting a device description). Windows only recognizes the device when I disconnect it from the USB and plug it in again with the button pressed (the blue and green flash light is on). I then installed the bootrom and fullimage again. It didn't help.

My terminal output:

$ runme64.bat

Re: ERROR: cannot communicate with the Proxmark

I execute make PLATFORM=PM3OTHER clean && make PLATFORM=PM3OTHER all and ./pm3-flash-all - Now it´s work without problems.
