[Galaxy S I9000 Q&A, Help & Troubleshooting] MS_Guru:
Some details for ya...

Just came across this myself. I was thinking maybe it was something similar to HTC's use of a CD-Rom USB interface, which loads an iso image containing drivers. Which frankly would make sense, seeing as most of us see a CD-Rom drive when plugged in via USB, well us Vibrant guys anyways, not sure about I9000. Out of curiosity I installed it on one of my VM testers. There's really not much there, and it seems somewhat dated. Here ya go. :D

Found this in Trigger 3.0.1. Also, the .inf lists quite a few files, but I never saw them. The installer extracted out to the following. C7xVX32S.sys, C7xVOIP.inf, an msi installer, and a few directories. The tester was 7 x86 Ultimate.

SWD-300_WiMAX_Drivers / 2ce9a.msi
