I can't help you with the USB port on the TS-7500, (although I'd love to see
some software/hardware that would do the job,) but I have just finished a plain
old regular RS232 UART port on pins (5,6) (7,8) and (19,20) (UART0, console,
UART1 respectively) that work just fine. Reads and writes to the UART's no
problem, and I'll be adding the log file to disk very shortly. You are welcome
to that solution if you like.
Why exactly do you want to go through the USB port for Serial RS232
communcations? I apologize in advance for this question. I know you are
looking for a USB solution and I know personally I hate when people offer
different solutions; however I do have what I believe is a complete
example/solution using the straight DIO pins for Serial communcations that I've
already tested on a TS-7500 using the debian linux OS.
I would like in general to know more about using the USB ports also, but for me
it was much more straight forward to use an old fashioned UART on pins.
