OK, here the result for tests, using 2.6.10-rc2-mm4. I've to put a options usbcore old_scheme_first=1 in modprobe.conf, otherwise the device is not detected. With this option set, all works just fine (no ub module compiled or loaded, if needed I can try also with this): no oopses, no call trace, it just works :) The only small issue is that if i leave plugged the usb flash key and power-cycle my box, at boot the device is not detected and it fails in the same way it happens when usbcore old_scheme_first is not set (it's present in modprobe.conf) If I unplug/plug the device, all works just fine. Great work !
