Hello OsmanAkin,
You still can manipulate these settings to share USB devices with VDI, using the Set-RdsHostPool cmdlet with the -CustomRdpProperty parameter.
https:// docs. microsoft. com/en-us/azure/virtual-desktop/customize-rdp-properties
If you look at the supported settings, you will find the drivestoredirect setting, controlling the drive mappings. If you set this CustomRdpProperty to drivestoredirect:s:*, all new devices should be available as well
https:// docs. microsoft.c om/en-gb/windows-server/remote/remote-desktop-services/clients/rdp-files
On the other hand, if you run a test with other USB devices and they are successful, there is the possibility that you may need to install some driver, partial key certificate or certificate tools in the VDI session in order to work correctly and be detected. For this, would be recommended to get in touch with the manufacturer of the device in order to understand the mechanisms needed for the device to be detected successfully.
