I'm developing a datalogger that only needs USB functionality to read out the measurement. Is there a way to completely power off the USB block during measurements? My goal is to be able to save power (and use the USB ram for other purposes). I found the USB_Disable() function, which could be just what Im looking for, but I need some mechanism to detect when a cable is inserted to re-enable USB. How does one do this?
