The FTDI boards are what you are looking for. We have a flakey internet connection here at work at the moment so I can't get to the website to verify the model numbers, but they have both RS-232 and -485 versions, both of which come in 1, 2, or 4 port models.
I have a 4-port board which I have so far tested with Ubuntu on a BeagleBone Black. Simply plugged it in and the four ports appeared under /dev/. Ran a couple quick loopback tests to ensure functionality and didn't see any problems. I had no driver problems of any kind, but they do provide linux drivers for download on their website. You will also not have any prolific similar drivers problems even if used on Windows. I purchased mine through Mouser. Fair price at the time and excellent service.
