Is it possible to configure the USB host functionality in a way so that only one bus-powered USB device is enumerated which claims a maximum current of 100 mA and rejects USB devices which ask for more current?
Background: We use a battery driven efusA9X board with WEC2013 and want to limit the current provided by the USB port to avoid that USB devices deplete the battery too fast.
The device supports the USB classes mass-storage and printer.
In this context I have noticed that the USB host at our device does not support external hubs (self made kernel). I'm wondering if it is possible to add support of hubs? I have found no appropriate catalog item to do so.
