The Eye Tribe

I'm using a usb mouse and keyboard. Once I plugin the eye tracker, the mouse freezes. When I try to start the server and plugin eye tracker in second step, the mouse moves but the keyboard's dead. I'm using the SDK 0.9.40 on a Mac Mini running OS X 10.9.4

That's a strange behavior... It sounds like an issue with the USB host. Do you have the option of plugging the device on another machine?
