Samsung Android 4.3 update nightmare

My old Galaxy note had the 4.3 update.
Now the usb connection doesn't work.
Thank goodness we can copy the photos via the micro sd card.

Hoping another update fixes this.
We did try to put the phone into debugging/development mode but still it doesn't work.

What's funny is my S5 was updated to 4.4.2 and it works fine.
Takes a while to get used to the difference in the left bottom button, where you have to hold it down for a few seconds to get the app menus as a single tap is the switching option.
