Child's Play? I'm on Square One!

I’m expecting this is child’s play to most of you, but having struggled a bit with a driver, I’m still trying to “start the engine”
Board is Genuino Uno. Driver is USB Serial CH340. Port is COM 50. Choice is 1 or 50 and 1 did not work!

Board Info request returns
BN Unknown Board
VID !A86
PID 7523
SN Upload any sketch to obtain it.

I pick a simple sketch from the examples and try uploading. Upload takes a long time and returns the message…
avrdude: stk500_recv(): programmer is not responding
avrdude: stk500_getsync() attempt 10 of 10: not in sync: resp=0x7b
Problem uploading to board. See for suggestions.

What am I doing wrong, or not doing?
