Hi all, I found a no name/brand PS2/USB MIR and wonder if it works for Asus TXP-4.

This is the pinout for TXP-4:

The pinout for the no brand MIR is slightly different (if assuming it is even the correct pinout?):

It has a F+5V where there is no connection on TXP-4, and FIRRX on #8 where there is also no connection. I don't think it's something standardized? has anyone tried the generic made in China cards and is it compatible with Asus combined PS/2 header?

I also am unsure if I can plug a 2x4pin PS/2 connector (If I can find an external 4pin PS/2 bracket) onto the PS/2 part of the board's header, and a separate USB 10pin connector onto the USB part of the header. Will this also work?
