Thank you Daniel, I am using the standard USB header, so to make it work I have to change the header and and connect the USB cable to the mass storage USB to make it work, do I ?

Best Regards
Fredy

I am trying to detect my device using the GTT designer but it does not work, but using the GTT support tool i am able to send command to the device.

I am using a GTT43A connected by a USB cable
