chicklet won't work

[bsbllpss]

our team is using a usb chicklet with our control system
everything works fine on it except for one thing
we plug in the power than the joystick and everything is fine
we drive for a little bit as little as one command and then the robot freaks out and starts doing a random command
this is not a programming problem as we plug in the serial joystick and it works fine...continuously
the chicklet only works for about 3 seconds

The behavior you are describing sound like a dead battery. Use a 9 volt power supply or a fully charged battery and this problem should go away.
