I am using a i.MX27L together with the MC13783 chip.
I am not using the builtin USB Full speed circuit in MC13783, instead I have added a High Speed PHY from SMSC with OTG Support on the OTG port.
Currently I have a seperate dual path configuration for the power supply. How can I charge from both a USB Host (PC) and Wall adapter without pulling more than 500mA from the USB Host? Can it be solved by changing the path or do I need externa circuits ?
