Damjan,

Your patch (applied manually to wine version 1.1.3 on gentoo AMD64; some of the
logic had changed around the spot where your patch went, but I was able to
still get it to work) fixed my issue with iGuidance 4 (a GPS navigation
program) talking to my USB GPS receiver. It now works, instead of not being
able to connect to the GPS receiver. I'm going to test it with wine 1.1.13 as
well, since that just went to ~arch recently. Thanks!
