Can't install drivers for Sentinel HL

Hi,

I'm running VirtualHere client vhui64.exe v5.1.6 on a Windows Server 2016 Hyper-V VM, connecting to VirtualHere Server vhusbdwin64.exe, also v5.1.6, on a Windows Server 2016 Hyper-V host. I did not install Bonjour on the server, since this is a very straightforward permanent network connection and I didn't see any need for a discovery service.

I'm trying to forward a SafeNet Sentinel HL copy protection hardware dongle from the physical host to the VM. The application which uses the dongle comes with the Sentinel System Driver Installer version 7.5.8. I've installed that driver package on both the physical host and the VM guest. When I look in the server-side Windows Device Manager, I can see the Sentinel key listed, with a correctly installed driver.

The VirtualHere client can connect to the server and can see the "Sentinel HL" device attached to the server's hub. When I double-click the "Sentinel HL" to use it in the client OS, I get "Error 2 installing drivers, The system cannot find the file specified."

VH shows me the following log entries (which cover multiple attempts to connect the dongle, I think):

The USB device properties are:

VENDOR: SafeNet Inc.
PRODUCT: Sentinel HL
VENDOR ID: 0x04B9
PRODUCT ID: 0x0300
ADDRESS: 8

No one is using this device

Any advice on what I might need to do to get this to work?
