There is an example of a USB <-> RS485 schematic here which may be of interest:

It includes additional logic to automatically enable DE / disable RE on data transmission. It's one of the approaches outlined in Jan's book linked previously.
Ok good stuff i found that module https://handsontec.com/index.php/product/ft232r-usb-to-serialttl-converter-module/
will that work ?
Yip - that'll do it :-)
