Using Group Policy

• Open the group policy editor for the policy controlling your Citrix Receiver client's.
• Go to Administrative Templates -> Citrix Components -> Citrix Receiver -> Remoting client devices -> Generic USB Remoting (if this is missing you need the Citrix Group Policy Extensions, see here).
• Open "New USB Devices", select "Enabled", click "OK".
• Open "Existing USB Devices", select "Enabled", click "OK".
• If you need to restrict which devices get automatically forwarded, open "USB Device Rules", add the required rules and hit "OK".
• Run "gpupdate /force" as an administrator on the client computer you're testing on to make sure you have the newest version of the policy.

Using the Registry

• Create a new key located at: HKLM\SOFTWARE\Citrix\ICA Client\GenericUSB\Devices\VID18FB PID0200 (replace PID0200 with the product id for the product you're looking to forward).
• Create a new DWORD value named "AutoRedirect" and set it to "1".
