I am pretty new to Arduino.

I recently bought a USB Host shield from sparkfun and want to know how to use it.

It would be nice if somebody could point me to some tutorial which explains you how to connect a usb host shield to Arduino. Thanks!

Use it for what?

Did you buy a kit or a fully assembled shield? If you have a fully assembled shield, it only fits one way. A tutorial on how to connect the shield is hardly necessary.

If you bought a kit, you should contact the supplier for instructions on how to assemble the kit.

You realize, I hope, that all the USB Host shield provides is the breakout pins necessary to connect to the wires in the USB cable. You need to write all the software necessary to interface with whatever you have connected to the USB port, and may need to add additional hardware, if whatever it is you have connected to the USB port needs additional hardware to drive it.

I bought the shield, so that I can try connecting it to an Android phone using the microbridge library - http://code.google.com/p/microbridge/

I bought the semi-assembled kit - http://www.sparkfun.com/products/9628 I figured out that I have to use some breakout headers to connect it to Arduino and managed to connect it properly. I also used the USB Host shield library from http://www.circuitsathome.com/arduino_usb_host_shield_projects and was able to run the examples which are present in that page.

The main problem which I was facing was that, my version of the kit had a bug and I needed to configure the pins differently. Now I am working on compiling the microbridge library.

I guess I am kind of in the right track now. Thanks for the reply.

How will reconfiguring the pins correct a hardware problem?

Well, it's not exactly a bug. The actual problem was that the library and the hardware were not compatible.

You need to open up the library and configure the pins correctly (basically change the constant to refer to the correct pins).

The latest version of the shield from Sparkfun has this problem fixed.
