USB over Ethernet

One of the problems in a virtual environment is to deliver USB devices to virtual machines. Standard ESX VMs don't even have virtual USB hardware and they don't need them. The technology you should use instead is "USB over Ethernet (USBoE)". The idea is to install a driver on the client that comes with virtual USB hardware that reconnects to an USB Device Server or Appliance to use its shared devices.
There are a few appliances on the market, but I learned the hard way that most of them are not suitable for professional purposes. Most of them are not made for data centers and do not come with an 19" option, others do not have an automatic reconnect to their devices after a reboot, which is vital for sharing dongles for copy protected server software. These appliances are cheap and available for under $150, but to me the best solution is a server full of USB PCI adapters and an USBoE software package.
I can definitely recommend Fabulatech's "USB over Network" software, which works really fine though it is not the cheapest solution. Check out the trial version, I'm sure you will be satisfied with the results.

Darauf haben viele von uns lange gewartet: Endlich gibt es ein offizielles Dokument, wie man die beiden Vorreiter in Sachen Virtualisierung und Netzwerk zusammenbringt. Viel zu lange hat man sich bei VMware auf Aussagen wie "die Unterstützung von Industriestandards" zurückgezogen. Das ist grundsätzlich erst einmal richtig, aber jeder ESX-Administrator kann aus der Praxis bestätigen, dass die redundante Anbindung im Netzwerkbereich einige Tücken aufweist und alles anderes als "bullet-proof" ist. Abgesehen davon waren die meisten Features äußerst schlecht dokumentiert. Das vorliegende Howto schafft nun einiges an Klarheit.
