1 Controller Description
This controller provides bridging between the USB, the dual-enhanced UARTS, and the IEEE-1284 bidirectional
parallel port. This device contains all the necessary logic to communicate with the host computer using the USB bus.
In addition to the USB host interface, the device contains a 5-port hub that can be used for USB expansion. The
internal 8052 microcontroller contains 16K RAM that can be loaded from the host. All the device functions, such as
the USB command decoding, UARTS/1284-port setup, and error reporting, are managed by the internal
microcontroller unit (MCU) firmware.
