Currently Being ModeratedApr 4, 2010 7:52 AM (in response to maclover009)That just confirmed what I said. Specifically:
"Note: Some USB 2.0 ports and accessories do not provide enough power to charge iPad. When this occurs the message "Not Charging" appears in the status bar next to the battery icon."
BTW even though USB only provides 1/4 of the power that the charger does, I was able to "top off" my iPad battery using it. Of course the iPad said "Not Charging" but it was brought up to 99% after being on the USB port for 3 hours!Active: iMac (G5, G4), PB G4, iPad, iPhone, iPod, MP2100 Retired: iMac G3, A2c, Mac OS X (10.5.8), Mac OS 10.4.11, Mac OS 9.2.2, iPhone OS 3.1.3, Newton OS 2.1
