The ADDER Secure Port Expander can be used to provide an additional port for USB HID devices. It only allows secure, unidirectional connection of USB HID devices, so may also be used as a USB HID filter.

Port Expander: Connect one or two USB peripherals to the device input ports. They will be presented as a single, composite USB device to the host.

USB Filter: Blocks all USB traffic except standard HID devices, such as keyboard, mouse and touch screens. Equipped with an internal authentication chip.

Secure: Once connected, it is impossible to remove the device from the USB port.
