Oh sorry, VUSB is VCHG in my definition. As it seems the CSR has charger detection build in, a dedicated charger can identify as such by having D+/D- shorted (or 100R across). When doing so on the CSR module directly, this should tell the chip, that a dedicated charger is connected when you apply 5V0 to VCHG. No need to have "fancy" charger mode setup with Pull-Up/Down on D+/D-. (USBP/USBN respectively)
