USB Plug-n-Play Devices

Supported on: All Citrix Workspace supported platforms

Description

Use this policy to enable and disable published application or desktop access to the client USB Plug-n-Play devices. The Not Configured setting allows device access until you explicitly enable or disable access.

Registry

HKLM Software\Policies\Citrix\ICA Client\Engine\Lockdown Profiles\All Regions\Lockdown\Virtual Channels\DVC_PlugAndPlay

Value name: PNPDeviceAllowed

Enabled: PNPDeviceAllowed = true,false

Disabled: PNPDeviceAllowed = false

REG Builder

BETA

Configure the state and elements to generate .reg, PowerShell, Intune, and SCCM outputs.

These exports replicate the policy's registry effect. Editing the registry directly is not the same as applying the GPO through the management console (no gpupdate, no central reporting). Test before production; HKLM changes require administrator rights.
