After contacting Cingular, several levels of support at Samsung, and
Microsoft (none of whom were able to help at all), I FINALLY figured it out!
It actually wasn't so much a Vista issue as it was an issue of Intel hardware
incompatibility with Vista:
***IF YOU'RE RUNNING VISTA ON AN INTEL MOTHERBOARD, YOU HAVE TO DISABLE
"QuickResume Technology" IN THE BIOS!!***
Apparently Intel's VIIV QuickResume technology is not compatible with Vista,
so even if you've successfully installed the VIIV package AND the quickresume
driver set, the setting in the BIOS can cause obscure hardware problems when
enabled -- one of which is not recognizing mobile USB devices. The setting
can be found in the Power sub-menu of Intel's BIOS setup.
I hope this saves somebody else out there the many hours & headaches I've
spent figuring this out [and I hope Cingular, Samsung, & Microsoft are taking
notes since their "technical support staff" are supposedly paid to know these
