https://bugs.winehq.org/show_bug.cgi?id=44033 --- Comment #3 from Sergey Lepeshkin <LepeshkinSN(a)gmail.com> --- Hi! I just want to tell community about my solution to related problem. Problem: Program tries to automatically find serial port, which is emulated by Prolific pl2303 chip. Search is done by inspection of hardware id for every port, listed in registry. Solution: Hardware identification must be added to registry. I’ve just copied related records from windows xp registry to wine, and all works fine. My pl2303_wine_reg.reg file is attached above. It adds support for COM1 as PL2303 with hardware id Vid_067b&Pid_2303 -- Do not reply to this email, post in Bugzilla using the above URL to reply.
