AT&T/Sierra Wireless 305 HSPA modem (cellular hotspot) Using vmWare 5.0 in large datacenter, have AnywhereUSB/14 applicance, guest OS on VM is Server 2008 R2 (but blue-screens with Server 2003 on VM as well) - have the correct driver (as provided by Sierra tech support) and they (Sierra) say this combination works fine but it sure does not for me.
