Other Hardware 3rd Party Boards

Hi all,

I bought USB shield from the Amazon.in (USB Host Shield for Arduino Compatible with Google Android ADK Support UNO MEGA) . I just connect the USB shield with the Arduino mega 2560.

My project needs to connect the barcode scanner to USB shield. I am using the the USB host shield library downloaded from the Github and i tried the example code usb_desc. But i am getting error "OSC did not start" message in the serial monitor.
Could any body shed some light on this issue?
Even i tried with the other devices like mouse and keyboard, but it seems , nothing works. Do I need to do any extra changes in the code to make it work.

It is very urgent . please help on this.

I have a USB shield shield (Keyes) working with a Mega 2650. The keyboard example works. No changes required. Be sure the ICSP pins (2x3 header) are connected because the SPI interface depends on it. Try the shield on an Uno to see if it works or not.

I received 2 defective USB host shields from Amazon yesterday. Maybe we purchased from the same batch. The boards can be repaired with a little soldering.
