The MaxPower field specifies the maximum power that a device can draw from the host, when the device is bus-powered. Define the default value of 100mA default in the platform to allow to override it from the board definition. Some mobile devices will only supply 20mA. If a device is known to draw less current, adding this to the board config will make it work: <boardname>.build.usb_power=20
