I would like to use USB device in my virtual machine. The problem is that this type of devices can be detected only by Windows OS'es. Mac OS is unable to detect it. That is why I am unable specify the device in Devices > External Devices
- Start Parallels Desktop, go to Parallels Desktop menu > Preferences > Devices
- Click on '+' (for sever times) in order to detect needful device.
Under 'Connect to' Tab select your virtual machine.
- Reboot Windows.
Now device will be successfully detected in Windows.
