We have a design (OMAP3530 & TPS65950) that ties ADCIN5 to a voltage that is always on. The possible current is small, a maximum of ~18 microamps, but according to the TRM, a DC voltage on ADCIN5 isn't OK if VUSB3V1 is off.
So I modified the driver code to leave VUSB3V1 on, but now after powering the PHY and MUSB back on, the USB device isn't recognized anymore.
Is there something I need to do to get it to recognize the device if VUSB3V1 is left on?
Alternatively, can I turn off VUSB3V1 if ADCIN is non-zero, but quite current limited?
Thanks!
