That's good, but not necessarily related to the question. :)

| # usbmodules --device /proc/bus/usb/001/002

| usbkbd

Let's see the output from 'lsmod' or 'cat /proc/modules'.
I'm still thinking that those are the HID Boot Protocol modules
that you don't want to use.
Do you have /lib/modules/2.6.9/kernel/drivers/usb/input/usb{kbd,mouse}.ko
files? If so, please rename them to something that won't be
auto-loaded and try your test again.

Modify drivers/usb/input/hid-core.c, around line #1467 (in 2.6.9).
There is a hid_blacklist array there. Add your device's vendor ID,
product ID, and quirk (HID_QUIRK_IGNORE). Rebuild & reload the hid driver
and you should be all set.
