using app's hidapi.dll

https://appdb.winehq.org/objectManager.php?sClass=application&iId=19830

The windows application is able to enumerate hid devices but doesn't identify
or start talking to it's devices. The app comes with and uses a build of
hidapi.dll (version <= 0.9.0 based on it's exports).

I followed https://wiki.winehq.org/Winelib_User%27s_Guide#Building_Winelib_DLLs
and tried building my own hidapi.dll that uses Linux native hidapi-hidraw.
Using this the app does pick up the device, but crashes (probably unrelated to
hid) after ~5s in an ungetc call.

Turns out that pi_server expects specific device product strings. Wine
"scrapes" dev desc strings differently than hidapi does. The product string on
Wine ends up as a concatenation of manufacturer+product values when compared to
other systems.
