You can connect two usb devices (usb-host only works in winmo and linux so far). Two usb ports are inside and always connected to keyboard and displaylink device. The dvi(vga)-video out function only works in hd2 linux with displaylink framebuffer installed. The 5V for usb host can be provided from external power source (usb in) or from internal battery. The internal battery (700 mAh) can power hd2 and usb devices for approximately 30 min (depends on usb devices). The internal battery can be charged over usb in. It can also be charged with solar cell but it takes forever (The actual purpose of the solar cell is to compensate self discharge).
