vmware and virtualbox usb device in use not able to attach to VM
If you have a USB device that cannot be detached from the HOST and attach to your VM, one possible reason is because you are using USB 3.0 port the device. Change to a USB 2.0 port should help in that case. This was my case with Windows 7 running on Thinkpad T530.
