TDA4VM: always USB ON

I want to make sure the USB is always on.

To do so, make the USB_DRVBUS pin high and connect this signal to USB_VBUS.

In this case, will the AP recognize the USB POWER as if it is always on?

    The desire is to always have USB connection detected?  Are you operating as host or device?  If operating as host, the proper ID signal needs to be provided.  USB_DRVBUS should be driven high, and USB_VBUS should be high.  If operating as a device, only USB_VBUS is required.
