I downloaded this file.zip, I unpacked in the folder Arduino libraries and gives me the following errors:
I use Arduino:1.5.6-r2, Windows 8, Scheda:"Arduino Uno"

C:\Users\GIORGIOP\Documents\Arduino\libraries\Adb\max3421e.cpp: In function 'void max3421e_init()':

someone has a solution?

Ohps! I have not selected the type of Arduino ... you must select "Arduino Adk" or "Arduino Mega 2560"!!! with "Arduino Uno" does not work. Buti, Simeone can tell me which library I have to add to make it run with arduino Uno and obviously the Hosts shield??:-(

What does your /libraries/ folder look like? Tell me the directory structure please.

Hello Mr. Agoransson,
I can use this library only if I select in the Arduino IDE menu/Tools/board/Arduino adk or Arduino mega or mega2560.
But, this library does not work if I select the Arduino Uno or other.
The directory of my arduino library folder is:
•\Arduino
•\libraries
•\Adb
•\examples
Adb.cpp
Adb.h
ch9.h
max3421e.cpp
max3421e.h
max3421e_constants.h
usb.cpp
usb.h

I'm honestly not sure why it wouldn't work - I haven't tested it myself since I only published this fixed version for a course last year - and we happened to use the Mega ADK in that course so unfortunately these problems didn't happen then. I'll have a look at why it doesn't compile for Arduino UNO.

I've been researching a while now and it seems it's a problem with the underlying libraries.

Have a look at this thread:
http://www.answerques.com/siBJgqXXQUSe/cant-compile-the-demokitpde-for-android-adk

If you scroll down there are a few suggestions for fixing this, personally I would attempt to downgrade Arduino IDE and see if that helps, then move to the other suggestions.

I found the solution, after thinking about it a week, I came to the solution. Now this library can also work well with the ArduinoUNO board.
The solution is very simple, just delete these three lines of code in the "MAX3421e.cpp":
DDRE &= ~ 0x40;
DDRJ &= ~ 0x08;
DDRJ |= 0x04;
if the code must be compiled ArduinoUNO, these memory addresses do go cresh compiling code.
I hope you can fix this library for all those people who are passionate about Arduino.
Tank you!
