USB hubs and the new Apple keyboards
Authored by: fastolfe on Sep 30, '07 08:55:45AM

Yes, it sounds like the hub is buggy. Normally devices are required to ask for power, and the hub is supposed to do some power management. If the hub isn't self-powered, it's not supposed to allow it, because it only has the power provided by the upstream to divide among all of the potential devices it serves. It might work OK for one device but it wouldn't surprise me if connecting a second caused the setup to become flaky or result in a crash. If the keyboard were capable of driving high-powered devices, they'd have probably let it.
