High Performance Low Cost Embedded Systems
USB Interface
The mini2440 has two USB ports: USB Host and USB Slave. The USB Host is the same as a USB
port in a PC and can be directly connected to and works with a USB camera, USB keyboard, USB
mouse, USB drive and other USB devices. The USB Slave is used to download programs to a target
board. When the board is running WinCE, it can synchronize with Windows through ActiveSync.
Because there are no proper drivers or applications for Linux, there is no way for the board to
synchronize with Linux now. The mini2440 has a USB_EN pin which is for users to control the
communication between the USB Slave and a PC via software. It uses CPU’s GPC5.
