Unplugging and replugging USB cable from PC seems to have repeatable behavior. Cable out, immediate amber LED off. Cable in, ~200msec delay, LED on, USB Charger detected, ~500msec delay, backlight on, ~600 msec delay, USB not detected, 600msec delay, backlight off, ~400msec delay, LED off, 500msec to 2sec delay, repeat about 4 times, then stall with LED on... It acts like software trying to find or do something that fails, but I need a serial port connection to see what what this "USB Charger" mode cycling loop is all about...
