Unfortunately, we do not test the 1-Wire drivers against virtual systems.
It is actually VMware's responsibility to enable a USB connection between the Virtualized OS and the Host OS. So, you may want to ask VMware for help. We are not aware of any 1-Wire Driver "howtos" posted. Our USB driver is actually Microsoft's WinUSB (no changes).
Here is the only article we have found on VMWare's website (very generic): http://kb.vmware.com/selfservice/microsites/search.do?cmd=displayKC&docType=kc&externalId=1008576&sliceId=1&docTypeID=DT_KB_1_1&dialogID=96327326&stateId=0%200%2096329662
