HID device redirected with RDP RemoteFX does not appear at Winlogon desktop state

Question

Hello,

I have successfully setup HID device (FIDO U2F key) redirection with RemoteFX to Windows 2019 Terminal Server (on premise) .

I have used a device GUID "{745a17a0-74d3-11d0-b6fe-00a0c90f57da}". according to guide - https://learn.microsoft.com/en-us/troubleshoot/windows-client/remote/usb-devices-unavailable-remotefx-usb-redirection

And devices appear successfully when user gets into desktop, so desktop application may access the remote HID device successfully .

Problem: HID device does not appear/listed within the hardware, while RDP session is still on Winlogon desktop state. I have developed Windows Logon Credential Provider that needs to interact with such redirected U2F device to continue user login into desktop session.
and my Credential Provider on Winlogon desktop cannot access redirected HID device, Is there a solution for this problem?

Is there a registry setting or other API for RemoteFX RDP to enable earlier device redirection, during Winlogon desktop state ?

Thanks!

Hello @ Alesil-5695

1. Run > gpedit.msc on client machine

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

Open Allow RDP redirection of other supported RemoteFX USB devices from this computer
and select Enabled

2.On RDS host

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

Open Do not allow supported Plug and Play device redirection and select Disabled

3.In remote desktop connection, choose the device you want use in your remote desktop.

Hope this helps!

Karlie,
Thanks for your reply and the step by step guide!

Actually I did that allready and still U2F Key doesnt work/visible on RDP Winlogon desktop state. (on RDP user desktop it is OK)
I tried both checkboxes in RDC client, "Smart cards and Windows Hello... " and "Other supported RemoteFX devices".

My credential provider does not sees "U2F" HID device within the HID Class devices.

So more help is needed from MS support definitely.
