Leonardo using Sparkfun USB Host shield solved

Using Arduino Networking, Protocols, and Devices

After some intense researching here and on Google I have solved my issue getting Sparkfun USB Host shield to work with Leonardo which no longer has ISCP pins on D11-D13 as UNO R3 has using the new revision of USB Host shield 2.0 library. My goal was to gain control of my Canon EOS 7D

I wrote a small guide (see PDF attachment) containing a lot of photos that hopefully will help others currently experiencing the same issues I had.

Its also the first version and may contain errors misspellings :slight_smile:

Followed it but still not working. Reading Revision Register is failing.

Checked D10. It is properly connected.
