Hello, I have 12 laptops with 3 usb devices connected to each and recently got a Dell R720 to try to run some vm's in order to downsize all my laptops. I got some 7 port pci cards, can I forward 1 port per vm and use a hub for the 3 devices or do the devices have to be plugged into the card and forward from there?
 
You cannot USB passthrough a whole hub at once but you can USB passthrough every port of a USB hub separately. And every passed port can go to a different VM (maximum of 9 per VM, I believe). Do note that USB passthrough is not well suited for low-latency or high-bandwidth usage due to (CPU) overhead.
 
Thanks! So what would be considered high bandwidth? I think I would be running a max of 30mbps on each vm

Thanks for the help, I was able to get 1 vm set up with my devices working with usb pass-through. I have 20 of the same device that I'll be using 2 of on each vm, is there an easy way to handle that since they will all have the same name ?

Select "Use USB Port" instead of "Use USB Vendor/Device ID". You'll have to remember which ones are already assigned and connect one device at a time so you'll know which one is the new one. Or figure out the port numbers, which you probably will anyway while you are doing this 20 times.
