We have had good experiences with the ATEN products using the uplcom(4) 
driver on FreeBSD for the last 8 years or so. The only issue we had was 
that connecting more than one of these adapters to the same machine 
occasionally caused trouble (as I remember, because most of the adapters 
shared the same USB ID).

We also connected serial ports of embedded devices to USB using adapter 
cables based on an FTDI chip and those also worked great with the 
uftdi(4) driver.
