[Cube] 22" & 23" cinema display differences?

[Luis Meleiro]

Hmm... Mactracker says Apple Cinema HD Display 23 - Power: 70 watts and
Apple Cinema Display 22 - Power: 50 watts. 
 
A side note from lowendmac.com: 
 
The Cube Speakers require special 10-watt USB ports to work at full
volume. The G4 Cube has these ports, as do all Apple ADC monitors. These
special USB ports are sometimes called 20-watt ports by Apple, because
the two ports share a single 20-watt supply of power, however, the Cube
Speakers only use 10 watts. The Cube Speakers will work on any Mac with
USB and Mac OS 9.0.4 or newer, but the volume will be much lower. This
is because regular USB ports only supply 2.5 watts. You can use the Cube
Speakers at full volume with a G4 tower if it has an ADC monitor and
they're plugged into an ADC monitor's USB ports. However, they'll only
work at a reduced volume if plugged into the G4's own ports or a USB
hub. 
 
Have you trid resetting P-RAM/NVRAM? 
 
Just a thought...

The problem is not in the display/graphic card, but in the USB ports 
that don't seem to be able to drive the Cube USB speakers like 22 
display did.
