Some background: Where I'm working right now, we have a server with two virtual machines (running servers) on it. As far as I know, the server uses vSphere (VMware's host for virtual machines or so it seems... enables management and setup of virtual machines on the actual machine...) Each virtual server runs Windows Server 2008 R2. (For our purposes, it's not really important that there are 2. I only want this to work with one of them anyways.) The issue: There is a USB 3.0 hard disk drive plugged into the actual physical server right now. The problem is that I can't seem to connect it (using the vSphere interface) to the virtual machine that is running Windows Server 2008 R2. I've read this: http://www.techrepublic.com/blog/networking/how-to-add-usb-devices-to-vsphere-vms/5623 It was helpful in getting me to the point where I added the USB controller to the virtual machine. Now I need to add the USB device. But... it doesn't show up. Anyone have any experience in this? Any ideas?
