As most of the USB Open Source Projects, Memtype project needed a VID & PID to be identified during enumeration process. As buying a VID/PID number was not in our minds, we decided to adquire a PID with the help of http://pid.codes/ . This guys are giving a PID number to projects witch are open-source hardware (VID is fixed to 0x1209).

Thanks to pid.codes guys we obtained a PID for Memtype project and our USB device enumerates with the following VID/PID values: VID: 0x1209 --- PID: 0xA033

The VID/PID change has also been updated on the source code: https://github.com/jim17/memtype/commit/fb8d2c7cbb0eb8e9539f830e526f6a31fffdd7d4

Steps to follow to obtain a Free PID are described in: http://pid.codes/howto/
