Hacker [Sprite_tm] is one of our favorites. He continues to court our fancy with his latest hack, adding a USB host port to his GP2X. The GP2X is a Linux based handheld game system. It supports USB devices through its EXT port. Problem is: it doesn’t provide power and you have to use a dongle. The GP2X uses a MAX1566 DC-DC converter so Sprite_tm was able to get 5V from the chip that was otherwise unused. Once mounted in place all he needed to do was write a simple script to mount the USB device. The chip should provide 500mA, but it’s not guaranteed. High draw could lock up the GP2X so a powered hub should still be used if you are unsure.
