How about doing your own MDB-USB adapter using either the FT232 or
related (if it can do 9-bit serial) or some more capable USB
microcontroller.

You could even use a microcontroller as a bridge between 8 and 9 bit
serial.

What you would want to do is check microcontrollor data sheets and
find one with a serial port that can be programmed to 9 bits.
