wine users - Jan 2009 - Help with USB-to-serial cable

I am trying to use software to program a scanner radio (BCD396t and UASD
software). The software installs and seems to run properly, reading and writing
database files. But I cannot connect to the scanner, through a USB-to-serial
cable.
OS: ubuntu-8.10, kubuntu-8.10, debian/lenny (tried them all)

lsusb identifies the cable as follows:
Bus 002 Device 002: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port

I set up the link in dosdevices as follows:
ln -s /dev/ttyUSB0 com5

When I change the baud rate in the software, and then check with stty, it is
changing the baud rate on ttyUSB0, so that part works. This computer has only
USB ports, no serial. I actually have several other devices with the same
problem -- need to program with USB-serisl cables.

Any ideas how to set this up?

This may not be a consolation, but USB to serial converters are
notoriously unreliable (we use them to program Omron & Allen-Bradley
PLCs).  IIRC it had to do with the way they implement CLK timing (which
is why your bps can't be set properly.)  More often than not, they
haven't worked for us under a real Windows installation so I'd imagine
you are really playing with fire using it under Wine.  You may want to
try a cable that doesn't use the PL2303 bridge.  

Sorry I don't have any better solution for you,

Yeah, I'm beginning to get a real bad feeling about this...

It does work in XP, no problems there.  I thought it might be some nit-picking
little configuration thing I overlooked, but maybe not.

Thanks for your input.

Found the port settings in the registry, and added an entry for the com port I
am using. Didn't help.
The next thing I am going to try is to get some details of the communications
protocol, and see if I can send stuff directly to the scanner through a terminal
program, both from linux and then from wine. I should be able to figure out port
settings that way, or whether this is going to work at all. I will post back
here with results when available.
