I recently purchased (http://www.arduino.cc/en/Main/ArduinoUSBHostShield) and seem to be having an issue getting it to connect to anything. I am using the USB Host library hosted by Oleg and attempting to use the examples and QC tests written by Lauszus but when I enable debugging and run the QC script I get the following error. The board is a duemilanove.

Is there a known conflict between the arduino.cc USB host and the "USB_Host_Shield_2.0" Library?
Are you using it on an Arduino UNO?
The board is a duemilanove.
The Duemilanove should work. Have you got anything else connected to pins 10, 11, 12, or 13? I wonder if the old-style LED circuitry on 13 is causing a problem. Do you know anyone with an UNO you could try?
Well I have been overdue for an upgrade to a larger board anyway, I guess this is my justification for getting a new 2560 board.
Bought a new 2560 and get the same error.

Sounds like something is wrong with your USB Host Shield. Probably time to contact whoever sold it to you.
