The Startech device, with the TI chipset, continues to have the same problem. I've tried a couple of other converters, Keyspan and Trendnet, both of which use the Prolific chipset, and they do work, making both /dev/serial devices and /dev/ttyUSB0. It may be fixable with the Startech converter, but since the other converters work straight out of the box, I'm just going to use one of them and move on to the next step of making my system work.
Thanks for the help, Nuno!
