Use smartcard reader on VM via Opti 3000

Hello,

We have a physical machine that we want to replace and migrate to a virtual environment.

• VMware - vSphere
• Windows 11 virtual machine
• Dell Wyse Optiplex 3000 client with ThinOS
• Smart card reader: ACS 38U

ThinOS version: 2411 (9.5.4070)

In the admin policy settings, MAP drive, sound, smart card, etc., are all enabled. The same settings are also applied under the RDP connection settings.

When the smart card reader is connected to the client, we can see that it is recognized. If we insert a card, the client detects it as well.

We connect to the VM via RDP.

However, inside the VM, the device manager does not show the connected card reader at all.
(Cross-test: If I plug the smart card reader into a Windows 11 laptop without installing any drivers or software, the device manager immediately recognizes it and lists it properly.)

So, logically, the smart card reader should also appear in the virtual Windows 11 machine.

The issue:

Inside the VM, there is a specific software that we need to use. Interestingly, this software detects that the smart card reader is connected, but it does not read the inserted card.

Tried to install drivers in VM, but nothing changed.

Any ideas?

Regards-
