USB 0 and USB 1 refer to the different USB ports. Your machine has two
USB ports 0 and 1.

1.5.9 is the driver version number for the USB ports.

The 2 in USB 2 is a protocol version numbers. USB 2 is faster than USB 1.
But is also backwards compatible with USB 1. 

I don't know if the G4 had USB 2 ports on it or not, but in any case, the
printer will work fine.

2.8.7 is the driver version number for the FireWire bus.
