→USB forwarding
There are two parameters, both need to be enabled for USB forwarding to work (yes, the default is that both are on):
* "'''Citrix USB forwarder'''" in the "Services" section* "'''Generic USB forwarding'''" in the ICA parameters section of the actual connection.
The Citrix USB forwarder is a system service, thus it can be configured from the "Services" parameters, not the Citrix ICA connection parameters. The startup behavior is controlled by the parameter named "'''Citrix USB forwarder'''" parameter. It has these options:
* "with Citrix connection". This is the default. Start the Citrix USB forwarder only if there is a Citrix connection configured.
* "on". Start the Citrix USB forwarder after system boot.
Futhermore, you can allow or deny specific devices by using the "'''Allow devices'''" and "'''Deny devices'''" parameters in the "Services"/"Citrix USB" parameters. These parameters directly modify Citrix' usb.conf file and thus accept the original Citrix syntax only [1]. Multiple stanzas, each one describing one device, stanzas separated by commas, can be added to either of these parameters. A stanza consists of tags that in turn have the form TAG=VALUE. Acceptable tags are:
* '''VID''' Vendor ID from the device descriptor
