Local Scanner Redirection issue in Azure Virtual Desktop while accessing Session host through Bastion authentication instead of RDP

Mirza Irfan Anjum 0

Hi, I am unable to redirect my local USB scanner when I access the session host (Azure VM) through RemoteApp. Please note I am using Bastion authentication instead of direct RDP due to security. The Scanner model is EPSON-DS-1630. When I check Device manager in my Azure VM it is showing below unknown devices. I am not sure that it is related to that scanner or what. However, the drives for this scanner is installed into the Azure VM and I have verified it from control panel.

To resolve local scanner redirection issues in Azure Virtual Desktop (AVD). Note that this is a generic solution that you can try if in case you have not tried it already:

Enable Scanner Redirection: Check RDP settings under Local Resources and enable Scanners.

Update RDP Client: Ensure you're using the latest version of the Remote Desktop client.

Check AVD Configuration: Verify group policies and session host settings allow scanner redirection.

Install Drivers: Ensure scanner drivers are installed on both the local machine and session host.

Test with Another Scanner: Rule out model-specific compatibility issues.

Optimize Network: Ensure a stable, low-latency connection.

Consider Third-Party Tools: Use tools like RemoteScan for enhanced redirection if needed.

Review Logs: Check event logs for redirection errors under Event Viewer.

If issues persist, contact Microsoft Support or check for relevant updates.

Hi @anashetty ,Unfortunately, None of it worked. As I have already done these suggestion before approaching this platform.
If there is any other work around please do share. Moreover, please can you share that is scanner redirection is allowed if we use Bastion instead of RDP protocol?

Regards

Hi Mirza Irfan Anjum,

Try enabling RDP and please check if scanner redirection works with RDP, then you can confirm that Azure Bastion does not support scanner redirection.
If you have any further queries, please let me know.

Hi @anashetty

Appreciated your concern and support just want to share that I managed to resolve this scanner re-direction issue by applying below work around. But after applying these setting Reboot is mandatory and it will work for both either for direct RDP or access session host through Remoteapp.

Please install the Scanner drivers into the system from where you will be taking direct RDP of VM or accessing the session host from RemoteApp.

Note: Please note in my environment we have enabled Bastion authentication not the RDP. But below solution worked for both.

Then follow the below steps.

Please open gpedit.msc as administrator, and enable the below local GPO settings on the system from where you will do the RDP of below mentioned VM.

Under Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Connection Client > RemoteFX USB Device Redirection

Enable the policy Allow RDP Redirection of other supported RemoteFX USB devices from this computer

Under Computer Configuration > Administrative Templates > Windows Components > Remote Desktop Services > Remote Desktop Session Host > Device and Resource Redirection

Disable the policy item Do not allow supported Plug and Play device redirection

After applied above mentioned local GPO please run gpupdate /force in CMD by running it as admin and restart the system.

Once system is back after reboot.

Plugin the Scanner into one of the USB port in the system from where you will take the RDP of below mentioned VM.

Before login into the VM through mstsc or accessing it from RemoteApp, Click on "Show Option" >> Chose "Local Resources" >> Click on "More">> expend the "other supported plug and play (PnP) devices" and select all the devices shown here, most probably the scanner will be showing here.

Once you have connected check if a new icon on the Remote Desktop bar appears. This icon allows you to select which local USB devices are in use within the session. 7- Simply click the icon. Then select the USB devices you wish to pass through, click OK. Just want to share that I managed to resolve this scanner re-direction issue by applying below work around.
