My FEZ Domino works perfect. I created a nice clock app with an LCD.
I attached it to my XBox 360 USB port, but the app doesn’t seem to run properly. The backlight comes up, and the fez power led comes up, but nothing comes up on the display. To verify I took out the demo app (blink internal light). On PC usb power (my workstation, server, and laptop) it works. On the PC’s USB, I get around 4.66v. on the +5 pin.
On the 360 however, I get 4.67v, and 3.3v on the pins, but the led does not blink.
