Question

USB device identification/Serial String of Device Instance ID changes on Windows 10 Virtual machine ( Azure/AWS) lead a Device Enumeration problem on Windows

sandip patidar 0

Problem Statement: We have a USB-based device that is plugged in on a Windows 10 machine.

below is the Device Instance ID of the plugged-in USB device under Device Manager. USB\VID_XXXX&PID_XXXX`SSSSSSSSS-SSSSSSSSS` Where SSSSSSSSS-SSSSSSSSS is Device Serial Number String.

Now create an Azure virtual Desktop machine( Windows 10) and enable the RemoteFx feature on machines to enable USB device redirection from Local Windows 10 machine to Azure Virtual Desktop machine.

Connect local Windows 10 machine with Azure Virtual Desktop machine using RDP (RemoteFx).

The USB redirection is successful. USB Device is detected under Device Manager but on Virtual machine, USB Device Serial String is changed, Very strange behaviour.

New Device Instance ID: USB\VID_XXXX&PID_XXXX&REV_000X\\3&XXXXXXX&0&TSUSB-SESSION2-XXXXXXXXXX&3&XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX

Do you know why USB device identification/Serial String changes of Device Instance ID on Windows 10 Virtual machine ( Azure/OpenStack)?

I appreciate it if someone could help with this issue.

Read RemoteFX feature and Windows Virtual USB Redirection document but there is no explanation for this behaviour.

Read same issue on other sites but no solution available?

@sandip patidar I have reached out to the internal teams on this and will share as I hear an update. Thanks.

This is needed to provide sessions isolation for redirected USB devices.

Is this causing any issues for you? Please share how it is impacting you and what your end goal is. Thanks.

Hello, Thanks for your response and attention. I appreciate the same.

For point: On discussion with the internal team, it was shared that USB device identification/Serial String changes of Device Instance ID is needed to provide sessions isolation for redirected USB devices.

Could you please provide more detail about your above-highlighted point:

Could you please share any official Azure Virtual machine document/technical link that explains this new behaviour "USB device identification/Serial String changes of Device Instance ID is needed to provide sessions isolation for redirected USB devices" of USB Devices on VM?

Is it possible OR Is there any setting available on Azure Virtual Machine to use a USB device on a VM machine without changing the USB identification/Serial Number string? If available please share it with us.

Is there any architecture change on the Windows virtual machine to support USB redirection (changes USB behaviour on Windows VM)? We did not find any official document that explains in detail about USB redirection behaviour on the Windows Virtual machine. Please share the official document if available.

For Point: This is needed to provide sessions isolation for redirected USB devices.

Is this causing any issues for you? Please share how it is impacting you and what your end goal is. Thanks.

Yes, The new behaviour is causing issues for our product on the Windows VM machine.

USE CASE: Our software application when using/enumerating the hardware device looks for the serial number identifier string in Device Instance ID ( USB\VID_XXXX&PID_XXXX'SSSSSSSSS-SSSSSSSSS') for successful operation on the Hardware Device. There is no Issue on the Local Windows 10 machine.

But causing the issue on Azure VM (as changing Device Instance ID) when we use our software application ( Installed on Azure VM machine) with the hardware USB device ( connected to Local Windows machine and Enabled RDB USB redirection). We can not use our USB hardware product anymore on Azure VM with software applications.

IMP Note: Here USB Device is visible under Azure VM Device Manager without any issue.

Could you please also suggest some Standard/Generic approach to handle our product on Azure VM machine if there are any architecture changes on Windows Azure VM for USB device redirection?

Appreciate your quick response and help as this problem is a blocker for our product use on Azure VM.
