USB ports for virtual servers in VM Ware environment

I am working with three virtual servers in a VMware environment. I had an office administrator ask me if we can make one of the servers a fax server. I have done this on a physical server before with a USB modem for the fax line, but I've never before attempted this with a virtual server.

After researching options for using a virtual server as a fax server, it seemed like the best option is to use an Ethernet-to-USB "server," link the virtual machine to use it as its own native USB ports, and install a USB modem in the Ethernet-to-USB "server."

I have two questions: is this in fact a good idea? And if so, would this device work for what I'm attempting to accomplish?

I hope it is alright for me to post that link. If it is not, I hope an administrator will remove the link or tell me and I will remove it.

Thanks for any advice you can give me regarding this!
