The explanation is simple: reset from any state but P_ON throws us back into TRX_OFF, not P_ON. That's why the P_ON test only worked predictably after power-cycling the board. - prod/atusb (gpio_usb): removed P_ON test - prod/atben (gpio_ben): added comment to P_ON test explaining why it works in this case
