Ehhhh, maybe not such a good "Friend".

Never used that chip, but looking at the datasheet, it seems that it's mostly a "HUB".

It does accept rs232, keyboards, mice and stuff.
But the conversion is to USB, not RS232.

I don't see any way to read the keyboard with an MCU.
Could be I just haven't read far enough.

If you want FTDI, then I think the ...
