.Morning I hope you or well. I would like to ask how do you know if the USB host shield works? When I connect my mega to the pc and upload a scripted it loads up fine.  
But when I attach my USB sheild the program times out etc.

Before I try downloading the program i put my Bluetooth dongle in the usb and that doesn’t even light up.

I’ve tryed plugging it in via pc with a extra 9v batter since people.or saying that the USB sheild sometimes needs extra power.

I think its d.o.a but would like some help.  
Thank you
