Every USB channel allow to attach one USB device. Is like having 2 physical USB ports on your computer. If you don't use an HUB you can attach only 2 USB physical devices. Currently there's no software USB hub so one USB device takes one USB channel and by default only 2 USB channels are attached to the VM. Frediano
