Pointer speed is unusable slow. Is there any setting how to fix the problem? Can I provide some more data? Thanks.

great. the touchpad doesn't even look like a touchpad, it just does the mouse emulation. So to libinput (and the rest of userspace) it just looks like a 5-button mouse with 2 scroll wheels.

Until we have kernel support for that there isn't much you can do beyond trying to increase the pointer acceleration to maximum speed.
Comment 6 pavel.sklenak 2015-12-01 15:12:46 UTC
I see, that's not so nice. I will store the device in a drawer then. Thank you for your time and analysis. Let me know if I can help with testing.
Comment 7 Peter Hutterer 2015-12-03 04:37:55 UTC
closing this bug for now, this needs to be fixed in the kernel first. Please raise a bug there or if you're really keen you can start reverse-engineering the protocol HP uses for these devices.
Comment 8 Benjamin Tissoires 2015-12-03 10:58:48 UTC
Even this bug is closed, I would be interested in having a look at the raw events of your touchpad.
Could you please attach a hid-recorder (project hid-replay[1]) of few events reported by your device?

Attached hid-recorder output. Hope it helps.

Comment 11 Benjamin Tissoires 2015-12-09 19:50:48 UTC
Thanks for the logs.
From a HID point of view, your touchpad is seen with 2 types of reports, one for the buttons/wheel and one for the mouse events. There is nothing there which allows to think that there is a hidden mode where the touchpad sends true multitouch data.

There is nothing I can do for you, sorry. You might have more success by reverse engineering the protocol the windows driver uses, but this goes beyond the scope of this bug. Plus, I am not even sure that such a mode exists.

So that I bought a crap, good to know. Thanks for your feedback.
