Hi Mattia,

I'd try with the input subsystem and the synaptics_usb driver first but
it's just a wild guess. Your kernel log should give you more hints about
which driver is bound to the device and the sysfs tree under
/sys/class/input/event*/device/* has all the capabilities and
identifiers.

The following did not help:

modprobe synaptics_usb
cd /sys/bus/usb/drivers/usbhid
echo -n "1-1.3:1.0" > unbind
#now the mouse is without driver, does not move, and
#/sys/class/input/event2/device/device is without driver
cd /sys/bus/usb/drivers/synaptics_usb
echo -n "1-1.3:1.0" > bind
#error: no such device, mouse does not work, nothing in dmesg
cd /sys/bus/usb/drivers/usbhid
echo -n "1-1.3:1.0" > bind
#mouse works again without middle button

Hi Stephan,

in this case, you definitively want to talk to HID (and input) folks.
Adding Jiri, the HID maintainer in the discussion.

Your mouse does not seem to be handled properly by the hid subsystem
and needs quirks, or fix.

Can you send us some hid-recorder[1] traces of your device? We should
then be able to check what's wrong and hopefully fix the problem.

Cheers,
Benjamin
