[ale] [Slightly OT] Prolific

[Alex Carver]

I've had good luck with the Keyspan adapters.  I have a one-port and a 
four-port unit and both work fine.  Haven't popped them open to examine 
the chipset.  However, I haven't had a problem with renumbering ports 
when plugging into different USB sockets using them.
