JP1 Remotes

I destructively took removed the casing by scraping alongside one of the sides until I could put in a spudger, then twist it to remove the casing in a top half and a bottom half.

On one side of the PCB there exists a chip with the marking:

SIL
2104
F2217
1350+

This appears to be the CP2104 ...

I extracted the rootfs of the Sony TV that was posted here: https://xdaforums.com/t/sony-android-tv-users.3096901/page-85

USB serial with custom PID/VID. Not sure if it is generic or cp210x. Definitely not pl2303.
Haven't found how the custom PID/VID gets automatically detected as a USB serial ...

I'm looking at some USB IR blasters, and I see a lot of Sony IRB-BR1 on eBay.

It doesn't seem like it has been RE'd, so I went ahead and ordered one.

This is what I have found so far
