I just built your test firmware with a PIC18F87J50 USB PIM
with Microchip MPLAB 8.89 and MPLAB C18 3.44. Then I tested
it with libusbK 3.0.5.16 under Windows with libusbK.sys
driver, it seems to work. But this test does not involve
libusbx since libusbx does not suppport isoc transfer under
Windows as of now.
