 On XO-4, in the Terminal activity or the console, type this command:
 watch -d -n 0.1 grep 44: /proc/interrupts
 You will see output like this:
  44:       1669   icu_irq  ehci_hcd:usb1
 The second number is a count of interrupts, and increases when the USB
 host handles transactions.  Device insert, device removal, and key events
 cause this number to increment.  Learn how it behaves using a USB drive,
 USB mouse, or USB keyboard.  Then examine the effect of using the Makey

 If the counter increments when the Makey Makey sends key events, then it
 probably means the device is working correctly and the kernel has
 expressed interest in the events.

 A different interrupt number is used on XO-1.5.

 You might also try connecting the device before booting into the Open
 Firmware ok prompt, and see if key events are shown there.

 I agree with Daniel that "cat /proc/bus/input/devices" will be
