I use Keyspan USA-19HS and earlier models. They work well. althoug hI  
had problems when two wer used simultanuously. After filing a bug  
report, they claimed their new 2.3 versio nhas solved the issue. each  
adaptors created /dev/... special files that you can program with  
standard unix calls.

I also use silicon labs chips and their drivers worked very well even  
when multiple devices were connected. However they still have to port  
their drivers  to Intel OS X.
