Grateful is that I have problems because the tps76933 3.3v regulators on the enable pin have 3.3 volts that also go to power on the integrated pic but the regulators are not enabled because I imagine that they should have less voltage on the enable pin there is a resistance of 100 k the r15 which divides the voltage 3.3v and power on but because there are 3volts in power on how much should there be that's why I'm not sure why the vms 4.1 doesn't recognize the usb that's why I want the firmware, thanking you for your response there will be the possibility of knowing how check if pic18f65j50 is good
