Trouble Connecting Keyes USB Host Shield with Arduino Uno

This is my experience fixing a bad board but the board did not have the name Keyes so it might be different from your board.

Configuration 3 in your message corresponds to what I did to my board.

The serial console messages indicate the driver cannot find the MAX USB host chip. Check the 2x3 ICSP pins to make sure they are not bent or missing. SPI communications is via the ICSP pins.
