Hello Manish,

The supported approach is to make the USB device accessible to the VM through one of the following methods. The most common is to attach the USB dongle to the host, then create a Remote Desktop session into the VM with USB redirection enabled. In the RDP client, under Local Resources > More, select the USB device so it is redirected into the VM session. This works well for security dongles and keytags that rely on USB presence.

Another option is to use USB over Network software or a USB‑to‑IP device server. These tools present the USB device as a network resource, which the VM can then access as if it were local. This is often used in enterprise environments where dongles must be shared across multiple VMs.

If the dongle is a storage device, you can mount it on the host and then expose it to the VM as a VHDX file or pass the physical disk through using Hyper‑V Manager. But for security dongles, the RDP redirection method is the only supported Microsoft approach.

In short, Hyper‑V does not allow direct USB passthrough. You need to use RDP USB redirection or a USB‑over‑IP solution to make the dongle available inside the VM.

I hope you've found something useful here. If it helps you get more insight into the issue, it's appreciated to accept the answer. Should you have more questions, feel free to leave a message. Have a nice day!

To attach a USB dongle to a Windows-based virtual machine (VM) in Hyper-V, you can use the Enhanced Session Mode feature. Here are the steps to do this:

1. Enable Enhanced Session Mode on the Hyper-V host if it is not already enabled. This can be done in the Hyper-V settings.
2. Open VMConnect: Launch the VMConnect tool to connect to your virtual machine.
3. Select the Virtual Machine: Choose the VM you want to connect to from the list.
4. Show Options: Click on the Show Options button to access additional settings.
5. Local Resources: Navigate to the Local Resources tab.
6. More: Click on the More button under Local devices and resources.
7. Select USB Device: Check the box next to the USB dongle you want to share with the VM.
8. Connect: Click OK and then Connect to start the VM with the USB device attached.

After following these steps, the USB dongle should be accessible within the Windows-based VM under "This PC" or similar locations in the file explorer.
