If using Windows, 32bit OS's seem to be more friendly, otherwise, maybe a USB-Serial adapter that isn't based on the prolific chipset such as the FT232 based boards such as this one. Disclaimer, this is just the first such adapater that popped up on an ebay search.. I do not know or recommend this seller so do not buy from them based on this link. The link was just to illustrate what an FTDI FT232 based USB to Serial adapter would look like.
