Thanks for the reply, but I have the SamDung Galaxy Tab S2 that has the usb connection problem. The option box comes on and off several times, sometimes just goes away, sometimes I can catch it and make the choice. I choose always so I don't have to go thru that each time I want to fly. I have to start the tablet last, and litchi starts up, and all is well. Just a bit of a pain having to wait for the tablet to boot up. I've tried all the fixes I can find, and this is the best so far. If you have any ideas, I'm anxious to hear'em. Thanks again, Gary
