[Olpc-open] Capabilities of XO's USB ports

[Jim Sayre]

Just a quick question: are the USB ports on the XO computers powered, 
and 2.0 compliant?  I ask because external hard drives have become less 
and less expensive, and there are now several models that don't require 
an external power source, ranging from 80 Gb to at least 160 Gb.  The 
retail prices are mostly $100 to $150 Cdn, on Dell's site for example.  
If these units are compatible with the XO's USB ports, they'd be a great 
way to add storage capacity to a classroom mesh network, without being 
dependent on constant electrical power.
