Hi! I have two kind of usb host shields that I'm trying to get working with my teensy 3.5. The first shield is a Keyes USB host Shield, the big blue normal one. The other one is a Sparkfun shield.
When I plug them into my Arduino Uno and run board_qc everything works flawlessly but when I then move over to my teensy I get:
"Reading REVISION register... Die revision invalid. Value returned: 09"
I have seen value 00 and FF as errors if some cable isn't connected but I have never seen 09.
I moved over each pin from the arduino to the teensy equally, 9 to 9, 10 to 10 and so on. The only pin I'm not sure of is the resest pin. I plug it into teensyns reset pin but it still gives me 09.
I'm using the USB_Host_Shield_2.0 library and I'm running both USB Host shield boards at 3.3v
Any suggestion why this could be?
Thanks!
