Re: Things to check? Crispy Fried Geckos? No motion...

Laptop and PC do not share a ground so there is no path between the
units.


second possibility, if it comes to this, is that the laptop does not
have a full 5 volts.

Whjy not use the laptop 5v pin on the joystick or external keyboard
port ?


interesting.... if the laptop is less than 5v, but the pc is 5 volt,
will ther be any problems ?
