Well.. lets try. I believe there must the way through. As a last resort
it should be possible to allow user select concrete model or parameter
set by hands..

I haven't dealt with hal drivers before, so I would appreciate if you describe
more precisely how to run it in debug mode :)

Output of 'lsusb -vvv' is following. For me it seems we have nothing like
ID, which could be used...
