The crash is kind of random. Sometimes it works, sometimes not.
Running with gui debugger or relay tracing it always works for me.

The app sends a JSP request and parses a rather large XML response which
contains lists of models into a series of string arrays.
It sanitizes/trims the input and removes XML specific data.

If the response status code for the model list request doesn't contain 'OK' the
app code misses out the creation of a string array.
This later leads to NULL ptr dereference when the carrier selection is done.

One reason could be return of partial data on first request for whatever
reason.

You might try: 'winetricks -q wininet'

Anyway, it's as Austin already said: what you're trying to do won't work by
design.

Wine is not an operating system and doesn't implement the "Windows kernel"
infrastructure needed to support these kind of hardware driver classes.

If your hardware is not recognized by your Linux kernel, you're out
of luck. Wine can't help you with that.
