Hi,

I was looking again at the Blackberry driver and its implications for
power management.
You are using the magic command always if you see the descriptor
for 100 mA. If you are on a battery powered hub after the reset, usbcore
won't choose a configuration. So far everything works as planned.

But what happens when anybody actually uses the device? Either he can't
as it is not configured, or he selects the configuration and the device will
draw the full power. Have you made the actual test what happens if
that bus powered hub has three other devices attached that draw the
legitimate 100mA?

	Regards
		Oliver
