here's is my problem :

But it appears to only be defined, not used in any code.

Now I'm pretty sure it's a Prolific 2303, as it works with the windows driver
for the pl2303, I looked in the kernel config
and there is a prolific 2303 module and it is being loaded. I can't tell you
much about it as I found it lying around, its a
little black box about the size of a match box with no writing on it at all.
My PL2303 has to be connected after the kernel module (uplcom) is
loaded (it's not part of my kernel).
attach USB end of PL2303
