How to add a virtual USB Drive to a Hyper-V VM

I have a Win 10 Hyper-V VM running and I want to simulate plugging in a virtual USB Memory Stick so that it appears in the VM as a drive letter in Windows Explorer.
The virtual USB Memory Stick is a vhdx file.

I could do this using Mount-DiskImage on the VM, but I want to do it from the Host (where the vhdx file is).

Put another way, how can I use Add-VMHardDiskDrive from the host, while the VM is running?

I want to do this using PowerShell, and I'm running Server 2019 Standard and the VM is Generation 1

Hi，

On the hyper V host, we may use powershell command to mount the VHD to the hyper V host: Mount-VHD -Path C:\Anne\mount.vhdx

Then, offline the disk on the host disk manager, and not initialize the disk.

Use the powershell command on hyper V host to add the disk to the VM: Get-VMScsiController -VMName hxw-node1 | Add-VMHardDiskDrive -DiskNumber 2

Thanks for the reply, but I think that is talking about physical USB sticks, not virtual ones
