Hi chandra

windows machine uses VID@PID values provided by i.MX6Q ROM,

they are programmed in fuses USB_VID[31:0], USB_PID[31:0]

described in Table 5-10. Fusemap Descriptions i.MX6DQ RM

http://cache.freescale.com/files/32bit/doc/ref_manual/IMX6DQRM.pdf

Seems there is no way to change them as they are burned in factory.

Best regards

igor

Hi igor,

Thanks for the quick response.

We are trying to change the name of the board which is connected to windows machine, not the VID and PID.

Is it possible?

Regards

Chandra
