I suspect this is the problem where "usbutils" hasn't
yet been updated to understand what modutils 2.4.1 is
writing out ...

If you update that, you might want to figure out where
to install "usbmodules":  /usr/local/sbin was where it
landed on my system, but that's not one of the normal
places to find things run by sysadmin scripts.

Curious, it most certainly worked for a mouse I tested it against.

Was that a combined mouse/joystick ... or a real mouse?  Did you
install both modutils 2.4.1 and Keith's patch?  And then rebuild
and reinstall your kernel, and reinstall all the kernel modules?

Rule of thumb for this version:  if a HID device doesn't hotplug,
it's going to need an entry in /etc/hotplug/usb.handmap ... that
will be true until someone starts to teach the "input" subsystem
how to hotplug.  (The previous version needed that for usb-storage
devices too ... but the ABI change made it easier for that driver
to hotplug, so usb-storage should mostly hotplug.)

I've not looked at it, but one way to start "input" hotplugging might
be to find out where "hid.c" sees devices' HID descriptors, and issue
call_usermodehelper() with information describing the device type.

An /etc/hotplug/input.agent script should be able to figure out
whether it's a mouse, keyboard, joystick, UPS, tablet, etc and
modprobe accordingly.

Where do I get an up-to-date usbmodules?  I've never had
such a utility and don't find it in the hotplug tar file
you posted.

Thanks!

After a bit of hunting around, I found that usbmodules
comes from usbutils.  I went to the usbutils home page:

	http://libusb.sourceforge.net/

But, the newest version of the package posted there is:

   usbutils-0.7.tar.gz 03-Nov-2000 17:51

I doubt this is what I need for testing.

Pointers to the right stuff?

	Miles

The only CVS tree I can find referenced in any way from
the homepage that mentioned usbutils is for libusb.
I downloaded the CVS version and built libusb, but I
see no sign of usbutils or usbmodules.  Do I just need
the CVS version of libusb and the latest released version
of usbutils?

Thanks,
Miles

Take a look at  http://usb.cs.tum.edu/download.html

Here's the command I used to download the libusb CVS source.
When I downloaded a released tarfile of usbutils, I found
that libusb seems to be contained within usbutils, but I
see no CVS module for usbutils.  Hmm.  Rats.

Here's what I tried:
cvs -z3 -d:pserver:anonymous@cvs.libusb.sourceforge.net:/cvsroot/libusb 
co libusb

Thanks Norbert.  I've got it now.
