usb descriptor bogus?

Hi,
I came up with an output descriptor for the Xbox 360 controller, but the
output from usbhidctl(1) is not completely as expected. The attached
file rdesc.txt contains the actual results, with lines starting with #
containing the expected results.
The output was generated using usbhidctl(1) and libusbhid from OpenBSD
with -rv as argument.
I also attached the descriptor itself (in .h and .hid format), the .hid
file was validated using Descriptor Tool 2.4. This is a small windows
program obtainable from http://www.usb.org/developers/hidpage/dt2_4.zip
Any ideas what is wrong with the descriptor (or maybe libusbhid) ?
Regards,
Rene
