can't open com1

[kombi]

Your highnesses!

When plugging in a pretty standard USB device (an opto coupler), running

dmesg -wH

nicely gives me:

[ +0.000183] usb 3-9: FTDI USB Serial Device converter now attached to ttyUSB0

which looks all fine. Also

ls -lh ~/.wine/dosdevices
com1 -> /dev/ttyUSB0

looks good! Wine regedit has

HKEY_LOCAL_MACHINE/Software/Wine/Ports
com1 REG_SZ /dev/ttyUSB0

and

minicom -s
9600 8N1

HOWEVER, I still get "cannot open com1"

What is there left to try or test?

Cheers,
kombi

I forgot to add:
cat /etc/group

Code: Select all

sys:x:3:kombi
adm:x:4:syslog,kombi
tty:x:5:kombi
kmem:x:15:
dialout:x:20:kombi

When do you get this message?
You may get more information about what is going wrong if you start the program with the comm debug channel.

Code: Select all

WINEDEBUG=+comm wine program.exe

[kombi]

Message appears when the program tries to connect to ttyUSB0

With WINEDEBUG=+comm wine [.exe file] the program does not start: https://pastebin.com/Amhpv1sj
