Adding USB Devices from an ESXi Host to a Virtual Machine
You can add one or more USB passthrough devices from an ESXi host to a virtual machine if the physical devices are connected to the host on which the virtual machine runs.
If a USB device is already connected to another virtual machine, you can not add it until that machine releases it. Make sure basic requirements are fulfilled.
- Right-click or go to the Action button and select Edit Settings for the virtual machine.
- On the Virtual Hardware tab, click the Add New Device button.
- Add a new USB controller, If not present already.
- Select Host USB Device from the drop-down menu. You will prompt to choose USB from the list that is already being connected to the hosts. (Add one USB device at a time)
- Click OK.
To verify this, Login to your server and check for disk management console in case of windows machine.
