            Bug ID: 43750
           Summary: USB "ttyACM0" serial port not being created
           Product: Wine
           Version: 2.17
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: wine-bugs at winehq.org
          Reporter: phoenix-precision at gmx.co.uk
      Distribution: ---

I have followed the new instructions at
https://wiki.winehq.org/Wine_User%27s_Guide#Serial_and_Parallel_Ports, to use a
Neo 7 GPS module.

I had to create the registry key HKLM\Software\Wine\Ports as it did not already
exist. I added a string value "COM1" with the data /dev/ttyACM0, ran wineserver
-k and started my application (u-center from
https://www.u-blox.com/sites/default/files/ublox-GNSS_u-center_windows_v8.25.zip
)

ls -l .wine/dosdevices shows the same four standard com ports as normal, no
change.

Next I deleted com1 and manually created the link to /dev/ttyACM0. When I
restarted wine the link had been replaced by the standard one again.

I also attempted to create COM5 via the registry key
HKLM\HARDWARE\DEVICEMAP\SERIALCOMM, but Wine is having none of it and deletes
it when re-started.

By starting the application and then manually creating the COM port link I am
able to use my device, so there is nothing wrong there. It is purely the
mapping of COM ports which is the problem.
