In case you are looking for an isolated USB rs232(proper +/- volts)/rs485/ttl(3.3/5v) port, look at this beauty. Sure you can get cheaper but the cheap clones from China usually all have the same usb ID string which causes issues under unix etc. These things have a random sequence in the ID which means none of that problem.
