Chapter 4: Configuration
USB Settings
HID only
If enabled, allows only HID (mice and keyboards) devices to be connected to the receivers.
Disable Isochronous Endpoint Alerts
When an isochronous USB device is connected to the receiver there will no longer be a warning message. Agility units do not
support isochronous devices.
Enable Isochronous Endpoint Attach
Some USB devices combine many USB devices behind a USB hub. e.g a keyboard with audio support. By enabling this option,
devices will be allowed to connect to Agility receivers, however, the isochronous part (e.g. the audio component) of the devices
will not work.
Advanced Port
This section allows you to determine USB port behaviour for use with certain USB devices.
The default is no reserved ports, Merging enabled and no feature code (or Quirk) set. It is recommended that these are left at the
default settings and are only changed under advice from a tech support engineer.
For each of the four USB ports on the receiver, certain rules can be applied depending upon the USB device connected.
If you have reserved USB ports on the transmitter, you can select which USB port to use for a particular device.
You can turn off USB merging for a particular port. This will slow down switching as the USB device will be enumerated every
time that you switch.
You can also enter an advanced feature if it is necessary for your USB device. The drop down lists the feature codes for some
known USB devices. Otherwise please contact your tech support engineer for advice.
