I’m running BenF 3.61, and it indicates USB, even after I unplug the cable and cycle power. It charges fine and it connects fine to my PC. The only issue is that I can’t see my battery indicator.
It gets stranger. With no cable plugged in, USB is displayed. If I plug in to charge, USB is displayed. If I turn the computer power off, but leave the cable plugged in, the battery charge is displayed. After unplugging the USB cable from the powered-down PC, USB reappears.
