I missed the other posts in this thread, but just recently I finished a
C++ program to communicate with a specific device (an HD radio -- for
carputers, it'll soon be part of LinuxICE). While the original cable
was intended to be connected to the RS232C port, I found that I had no
problem controlling the radio through a USB->RS232 converter. I used
an adaptor that identified itself as ATEN and the other person who was
testing my code used one with a chip from something like Prolific or
Proliant. I don't remember names like that very well.
I do know we tried one from a company called Cables Plus. I don't what
the chipset in it was, but it didn't work too well. It's possible it
could work, but I didn't have time to check all the settings.
I did find that I had to be extra careful to do things in my code like
make sure I specified to the serial port object (in C++) to hang up on
closing for the adaptor, so while they work okay, they do seem to be a
tad pickier on protocols, or at least some are.
And as for versions, I was doing the programming on Kubuntu Gusty (or
Gutsy if it hasn't had any beans) and it also ran well on Sarge.
Neither had any exotic kernel setup.
