You can configure USB to Serial adapters that use a Prolific chipset to be redirected to remote sessions by the serial port redirection feature.
To ensure that data is transmitted properly on Prolific chipset adapters, you can enable a serial port redirection group policy setting in Active Directory, or on an individual virtual machine desktop or RDS host.
If you do not configure the group policy setting to resolve issues for Prolific chipset adapters, connected devices can transmit data but not receive data.
You do not have to configure a policy setting or registry key on client systems.
Prerequisites
- Verify that the Serial Port Redirection setup option is installed on your virtual machine desktops or RDS hosts. The group policy settings have no effect if serial port redirection is not installed. For information about installing Horizon Agent, see the Windows Desktops and Applications in Horizon document.
- Verify that the Serial Port Redirection ADMX template file is added in Active Directory.
- Become familiar with the Serial2USBModeChangeEnabled item in the PortSettings group policy setting. See View Agent Configuration ADMX Template Settings.
Procedure
-
On the Active Directory server, open the Group Policy Management Object Editor.
-
Navigate to the Computer Configuration > Policies > Administrative Templates > View Agent Configuration > Serial COM folder.
-
Select the PortSettings folder.
-
Select and enable a PortSettings group policy setting.
-
Specify the source and destination COM port numbers to map the COM port.
-
Select the Serial2USBModeChangeEnabled check box.
-
Configure other items in the PortSettings policy setting, as needed.
-
Click OK and close the Group Policy Management Object Editor.
Results
USB to Serial adapters can be redirected to remote sessions, and can receive data successfully, when users start their next sessions.
