I'm new with Arduino.
Now, i'm triying yo use USB Shield ( http://www.sparkfun.com/products/9947
) but I can't.
When try to use this shield, I get: Error: OSCOKIRQ failed to assert
I'm searching a lot in Google, but I can find a solution for my problem.
I already try to use an external power supply for send power to USB Shield, but the same problem.
I think that the connections for USB Shield to Arduino Mega may be different from the connections tu Duemilanove, but I can find any schema of this, for make the correct connections.
Thanks for help!
