The USB Host Controller is Open HCI-compatible, Windows95
Rev 1.1 compatible. It supports both low- (1.5 Mbits/s) and high-speed (12 Mbits/s) USB devices.
The USB controls the transfer of data between USB peripherals (attached to the USB) and system
memory. The USB uses DMA to transfer data.
The two PS/2 ports can be used with keyboards, mice, trackpads or other PS/2-compliant devices.
The PS/2 pins behave like open-drain I/Os when used in PS/2 mode. When not used for PS/2
attachment, the pins may be used as General-Purpose Input/Output (GPIO).
