this excessive politeness rules out hand-crank charger, solar cell, battery-to-usb, and every auto-usb adapter out there. It's overkill. the usb spec requires the hub to reply to the request for more power. no reply within xx ms means there is no hub to ask. At this point it should be pragmatic and just use the @#&* 500mA. I tried to hunt this down in the source and I think it's in two places--uboot when off and the kernel when on. It was very hard to figure out who drives the control. brad _______________________________________________ OpenMoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community
