 I found the solution, just redefine the MAX_SS constant to 53 after that all tests passed !

 Can this be used in conjunction with the Arduino Ethernet Shield?
-I have a feeling that it won't work (well), because it uses pin 10 (which the ethernet shield uses as well) -- perhaps it would be modifiable?

 Hope this helps somebody out, and if SparkFun could do a revision of their board to include a solder jumper to change the SS pin that would be awesome. :-)

-Unfortunately, it will not. There is a conflict on D8 between the MicroSd Shield's CS pin and the Usb Host Shield's GPX pin.

 Also, the power led on the EWI does not turn on when plugged in (which it does when plugging it into a computer).
-Any ideas on what the problem might be? (I'm powering the Arduino with a 9V power adaptor and the EWI uses a type B USB cable (although I don't think this makes any difference))

 bye, zacharias
+=========================================================
+My Sparkfun comments:
+I can confirm that the Sparkfun Ethernet shield works with the USB Host Shield.
+To make mine work with Oleg's legacy code: 1. Cut USB Host Shield PCB trace
+going to IO pin 10. 2. Wire the PCB trace to pin 6. (this is the trace that used
+to be hooked to pin 10). 3. Change #define MAXSS 10 to #define MAXSS 6 in
+Max3421econstants.h 4. Supply a hefty source of 9 volts to the Ethernet shield.
+Running from the USB power is not enough!!! 5. Run boardtest.pde. Monitor using
+the serial monitor with monitor speed set to 115200 baud (the drop down menu in
+the lower right corner).
+The Sparkfun Arduino ethernet regulator is almost too hot to touch. Using an IR
+thermometer I measured 150 F on the regulator and 180 F on the reverse
+protection diode D1 feeding it.
+===========================================================
+Comments from stan001 on Sparkfun:
+I got V2.0 libraries to work with this Sparkfun USB Host Shield.
+I compared this board schematic to the Circuit@Home V2 board and found the differences.
+The Sparkfun board, MAX3421E RESET pin is wired to pin D7 whereas the
+Circuit@Home V2 board is wired to the Arduino RST or Atmel328 Pin 1.
+I just jumper the D7 to RST on the female header and it "kinda" works...
+Run the board_qc of Version 2.0 libraries and all the test is passed except the
+resets is a bit delay with the message below : \\
+Circuits At Home 2011 USB
+Host Shield Quality Control Routine\\ Reading REVISION register...\\ Die revision 03\\
+SPI long test. \\ Transfers 1MB of data. Each dot is 64K\\ ................ \\ SPI long
+test passed\\ [snip]\\ Resetting oscillator \\ Reset number 0 Time to stabilize - 687\\

+It will work and I can confirm it..
+Just solder a wire from digital pin7 to reset pin (next to the 3.3V pin) at the bottom of the Sparkfun shield.
+No software changes necessary on V2.0 library..
