I'm trying to find details on if it is possible for the ADSP-BF525 to negotiate with the USB controller to state that it is a high power device and ask for 500mA instead of the standard 100mA?
Is this possible?
Only the bus-powered functions (USB peripherals) can request 500 mA. If you are making a bus-powered device, then, you can request 500 mA specifying in the bMaxPower field in the Configuration descriptor. You need to specify the bmAttributes field of the Configuration Descriptor to indicate that the device is bus-powered.
