Hey Hans,

I have a <Logitech G500s Laser Gaming Mouse, class 0/0, rev
2.00/84.01, addr 12> which is reporting itself as both a mouse and
a
keyboard.  I know that the mouse has the ability to remap itself
as
it
used to not do this (I was able to configure this on a mac).

The annoying effect is that the "back" and "forward" keys now
report
themselves as "[" and "]" keys.

I think it would be a good idea to write a utility to configure
this
stuff on FreeBSD.  What information do I need to obtain / how
should
I
obtain it?  I'm guessing its possible to talk to the mouse over
USB
but I'm not sure how.



Hi,

Can you check the configuration descriptor first?

usbconfig -d X.Y dump_device_desc dump_curr_config_desc

Possibly you need to issue some HID command (set report descriptor)
to
make
the device change behaviour.

Hi,

USB descriptors look sane.

Add:

usbconfig -d X.Y add_quirk UQ_KBD_IGNORE
usbconfig -d X.Y add_quirk UQ_UMS_IGNORE

Then re-plug the device.

Now you should have /dev/uhidX

Run:

usbhidctl -f /dev/uhidX -rvx

For both uhid devices.

Thank you!

Hi,

Looks like a real keyboard. If you add a quirk to hide the keyboard,
does
the mouse function like it should?



If I remove the IGNORE_UMS quirk then the mouse works as normal until
I try to press the 'back' or 'forward' keys then the entire mouse
freezes: not even moment or normal mouse keys work


I guess that's because this mouse does not have very intelligent firmware
:-)

Try reading from the HID device which corresponds to the keyboard:

dd if=/dev/uhid0 of=/dev/null bs=20 &

bs= must be correct.

Does that help?


Yes it does: although the back/forward keys still don't work.


Hi,

I'm unsure what to do next. The USB firmware makers are simply getting more
and more creative :-) The surely didn't ask me if doing a USB mouse that way
would be clever :-)

It appears the mac utility can cause the mouse to enter different
modes.  I'm curious if there is any usb sniffer I can use for OSX to
see what commands it sends to the mouse.


Have you checked if "uhidd" might work better with your device?

I havn't tried this, but will do so when I can

Any suggestions for ways to talk to the mouse? I could try brute
forcing configuration options: Its shameful if we need to use a mac to
fix these sorts of problems.


Hi,

There is something called set report in the HID world which might change 
the behaviour. Just grep in usb_request.c. Else try google the product 
and vendor ID. Perhaps someone has already seen or has a solution for 
this issue already?
