ok, this clearly validates that we are facing an hotplug
problem! The right privileges (660 root:nobody) have
not been set...

So, 2 things:
1) why this hasn't been set?
I really don't know! but check this:
- /etc/hotplug/libhidups should be 755 (rwxr-xr-x)
- hotplug should call libhidups when the USB cord
is plugged back (try to unplug / replug the USB cord
and check the syslog)

2) simple tests
- call "export ACTION=add && export TYPE=USB && export DEVICE=/proc/bus/usb/001/002 && /etc/hotplug/libhidups"
The result must be that /proc/bus/usb/001/002" is set to "660 root:nobody"

Note that you need to adapt "001/002" as it changes
upon unplug/replug. You can check it with "lsusb"

- if the above is ok, then start newhidups in verbose mode
(having done an "export USB_DEBUG=3" before to get
libusb trace)

As always, thanks to send back the output of lsusb, newhidups
and "ls -lR /proc/bus/usb/" (and if possible, an excerpt of the
syslog with the hotplug message)

One thing is fine is that we are now sure that this is a hotplug
problem. The only remaining point is "how to solve this", and
it depends on "why this hasn't been set"...

fine thanks. Most of all, more time to dedicate to
my baby boy... and that's really magic ;-)
