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

+=========================================================
+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..
