USB Device Rules
Supported on: All Citrix Workspace supported platforms
Description
Used to specify which USB devices are allowed or denied. Each rule is case-insensitive and of the form {Allow: | Deny:} followed by any number of <tag>=<value> qualifiers. Multiple rules should be separated by semicolons. Comments start at '#' and continue until a semicolon. For example 'Allow: VID=1234 PID=5678 # Comment ; Deny: Class=03'. Supported tags are VID, PID, REL, CLASS, SUBCLASS, PROT.
Registry
HKLM
Software\Policies\Citrix\ICA Client\GenericUSB REG Builder
BETAConfigure 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.
