Magic trackpad 2 only works when plugged in
I have a magic trackpad 2 that is about two months old. I have kept it plugged in to my wired keyboard's USB hub since I got it, on a rare occasion unplugging it to use the cable to charge my phone. Today I tried doing that and when I do so it stops working. I see it in Bluetooth devices but connecting to it fails. When plugged in it works fine and shows as connected and full charged.
I find it hard to believe its defective, but maybe. Has anyone else experienced this? Any fix?
