The module programs the CYUSB2014 firmware. Location of this chip:
- in P3X and P3S, it is on GL300 Main board of GL300b and newer RCs
- in other products, the location is unknown
The chip receives video stream from the Lightbridge system FPGA, and serializes it for transmission via USB. The USB output can be directly connected to a mobile device.
There are multiple versions, always unencrypted.

All the published versions are without encryption.
The unencrypted firmware is a Cypress format firmware package. This can be verified by magic value of "CY" at the beginning of firmware file.
No analysis of the booting procedure were performed.
The firmware uses ThreadX RTOS. It is compiled with EZ-USB FX3 SDK software from Cypress.
The "CY" firmwares can be flashed into Cypress chip using EZ-USB FX3 SDK software.
Information on such re-flashing is available in FX3 Programmers Manual.
