I know that it's currently not possible to plug a USB 1.1 device into a 
2.0 hub connected to a 2.0 port.  I have no idea why this should be; 
I'll just assume that's some side-effect of weirdness in the USB spec.

However...  If I were to plug a 1.1 hub into the machine's 2.0 ports, 
and then plug a 1.1 device into that hub, would it work?
