Per section 4.3.12 in last year's rulebook, there are no explicit restrictions. however, the note associated with <R75> provided an implicit restriction:

Please note that 19V DC, 2A power will be provided at the PLAYER STATION for Classmates provided in the 2010 and 2011 KOPs via Classmate power adapters. The manufacturer has confimed that the power supply provided at the PLAYER STATION is compatible with both 2010 and 2011 Classmate versions. No 120VAC port will be available.

So, I would highly recommend avoiding all independently powered hubs... although I couldn't find anything in the rule book explicitly prohibiting batteries on the OI to power devices (like a powered USB hub).
Keep in mind that rules do occasionally change... you won't know what you can use this year until January.
Its not the type of material you use, but how you use it... - jrocket567 [more]
