USB VendorID and ProductID modifications

mnm-isola commented 1 year ago

Greetings, I'm currently looking if it's possible to change the VID and PID in the firmware of MS2109 / MS2130.

I'm in a situation where I have several embedded (and can not be tampered) Windows machine with broken cameras, and I have the idea of using MS2109 / MS2130 to spoof the camera check which looks for the VID and PID of the USB camera devices (and they also return all the correct video modes already).

Wonder if it can be done by either recompiling the firmware source (which I don't think they're available online) or by dumping then patching the firmware binary.

Hello,

On MS2109 it is trivial to modify the firmware to change the VID/PID. On MS2130 we first need to figure out how a 32-bit signature is calculated.

I am a bit busy now but can give more details in a week or so for the 2109 if you want.

Sincerely, Bertold
