I seem to have missed this thread and may get in touch with you off list
about sorting the problem. Modprobe effectively resolves any module
dependencies before loading each module required by a particular module
(it does this using the dependency information generated by depmod from
symbols within the modules themselves). In recent kernels it is also
possible for a device to dynamically cause dependencies to be loaded.

The detection code is not finding the joystick device (is it correct?).

Which port is it on, where is it, etc.?

Please send the contents of the relevent portions of those log files.

I happen to be revising the joystick driver code right now (not for
that device) for interest and also as it may come up in an exam today :-)
