Arduino beginner trying the library out and running while (!USBComposite); gives me a compilation error

Sketch1.ino: 101:9: error: no match for 'operator!' (operand type is 'USBCompositeDevice')
Build failed for project 'Sketch1'
   if (millis() > t + 250) {
Sketch1.ino:101: note  candidate is
Sketch1.ino:101: note  operator!(bool) <built-in>
Sketch1.ino:101: note    no known conversion for argument 1 from USBCompositeDevice to bool

Try: while(!USBComposite.isReady()); instead.
