Hi,
1.Did you check the hotfix history installed in this windows 1909? Sometimes patch the machines into latest will help address some unknow problems.
2.Kindly test below steps as workaround:
- Disable the "Remote Desktop USB Hub" (tsusbhub.sys) from Device Manager
- Enable the following setting: (Computer Configuration\Policies\Administrative Templates\Windows Components\Remote Desktop Services\Remote Desktop Session Host\Device and Resource Redirection\Do not allow supported Plug and Play device redirection)
- Enable the following setting: (Computer Configuration\Administrative Templates\System\Device Installation\Device Installation Restrictions\Prevent installation of removable devices)
Please note: Users will still be able to use removable devices that have already been connected and installed prior to enabling the group policy.
Hope this helps and please help to accept as Answer if the response is useful.
Thanks,
Jenny
