2.6.24: false double-clicks from USB mouse

2.6.24: false double-clicks from USB mouse

[Mark Lord]

I've only just recently tried running 2.6.24 on my main machine.
And it appears that I'll have to go back to 2.6.23,
because the USB mouse is not working correctly.

Single-clicking on things with 2.6.24 very frequently gives a "double-click".
This does not happen with 2.6.23.8.

I wonder what broke it?

I've grabbed mousedev.c from 2.6.23 and inserted that in place
of the updated 2.6.24 source, but no change.  So it's not that file.

?????

Mmm.. reverting the entire drivers/hid directory to that from 2.6.23
seems to have fixed the problem, so we now know it's in there somewhere.

Jiri: do you have any suggestions that might be more specific than that ?

Thanks

just making sure.. this is while running an untainted kernel without
something like vmware loaded, right?

Absolutely.

But thanks for reminding me.. I need to re-run vmware-config.pl now.

My USB mouse recently started giving me phantom scrolls (movements of 
the mouse wheel, even I made sure the wheel was in a resting position) 
in recently kernels.  It happened too infrequently for me to care.

Bus 001 Device 004: ID 045e:0047 Microsoft Corp. IntelliMouse Explorer 3.0

My USB keyboard also occasionally loses all contact with the number pad. 
  Other keys continue to work as expected.  Unplug/replug sometimes 
helps.  Reboot /always/ fixes the issue.

USB HID is a fun place to be.

Did this also start in 2.6.24, as in Mark's case?

Yes, especially with tons of USB HID devices violating the specs in many 
creative ways :(

It happens to me, too.
Wireless mouse, gives some "wheel up" signals when going into powersave
state. Kernel is 2.6.22-tmb-laptop-2mdv (Mandriva Cooker).

Maybe a more-or-less undocumented sequence to tell the host it's going

Is this a regression for you? Are you able to say which kernel first 
exposed this behavior in your case?

usbmon and/or HID_DEBUG output would be interesting to see (how to produce 
HID debugging output has been explained earlier in this thread, for usbmon 
please look in Documentation/usb/usbmon.txt).

Could you please run evtest on the mouse device and send me what is 
reported when these false double-clicks happen? Also providing debug 
output of usbhid might or might not be helpful (*)

There were not that many changes in USB HID apart from adding per-device 
quirks for specific broken devices. Could you please try reverting 
c01d50d18, 933e3187, 82eb1219 to see if any of them makes this go away? 

(*) this means compiling with CONFIG_HID_DEBUG and modprobing hid module 
with 'debug=1'.

Mmmm.. an update here:

Reverting the drivers/hid directory does seem to improve behaviour.

But right now I have a "make -j4" happening in the background
and the mouse is ever so erratic again, despite the drivers/hid reversion.

So it's a timing thing, somewhere.
Maybe a scheduling thing?

Jiri:  I know nothing about how mouse clicks are interpreted,
or even *where* or *how* double-click detection happens.
Until this started happening, I didn't even know which module
was the driver for my mouse (it's usbhid).

Can you give a short tutorial, to help us understand possible causes ?

..
Ghad.. now that the "make -j4" has finished, the mouse is *still* screwy,
whereas it was mostly fine before the "make -j4" started.

Time to reboot (for the new kernel, as well as to try and fix the mouse).

Thanks a lot for your report Mark. Before we start digging deeply here -- 
Dmitry, do you think that this could be caused by your input-locking 
patches somehow? From Mark's report:

- it didn't happen with 2.6.23
- when drivers/hid is put back into 2.6.23 state, the problem still 
  persists in some sense

So there must have been some change elsewhere (USB, Input, something 
completely different) that introduced this problem.

First it would be really helpful to see if

- the HID driver really obtains two click events from USB stack. This 
  could be easily seen from HID debug output. I have written in previous 
  mail how to obtain this
- the output of evtest for the mouse device in /dev/input/event? (for 
  determinign the correcnt event number corresponding to your mouse, see 
  /proc/bus/input/devices)

Here's a *single* button click (press/release quickly):

Event: time 1196621063.612542, type 1 (Key), code 272 (LeftBtn), value 1
Event: time 1196621063.612553, type 0 (Reset), code 0 (Reset), value 0
Event: time 1196621063.620504, type 1 (Key), code 272 (LeftBtn), value 0
Event: time 1196621063.620512, type 0 (Reset), code 0 (Reset), value 0
Event: time 1196621063.628497, type 1 (Key), code 272 (LeftBtn), value 1
Event: time 1196621063.628502, type 0 (Reset), code 0 (Reset), value 0
Event: time 1196621063.684524, type 1 (Key), code 272 (LeftBtn), value 0
Event: time 1196621063.684531, type 0 (Reset), code 0 (Reset), value 0
Event: time 1196621063.700532, type 1 (Key), code 272 (LeftBtn), value 1
Event: time 1196621063.700538, type 0 (Reset), code 0 (Reset), value 0

Event: time 1196621063.764550, type 0 (Reset), code 0 (Reset), value 0

Here's another one, except I held the button firmly down for a second or so,
and then released it:

Event: time 1196621197.179635, type 1 (Key), code 272 (LeftBtn), value 1
Event: time 1196621197.179645, type 0 (Reset), code 0 (Reset), value 0
Event: time 1196621198.323607, type 1 (Key), code 272 (LeftBtn), value 0
Event: time 1196621198.323616, type 0 (Reset), code 0 (Reset), value 0

I'll go work on the CONFIG_HID_DEBUG thing next.

Note that, much of the time, a single mouse click looks like this:

Event: time 1196621357.073485, type 1 (Key), code 272 (LeftBtn), value 1
Event: time 1196621357.073494, type 0 (Reset), code 0 (Reset), value 0
Event: time 1196621357.201482, type 1 (Key), code 272 (LeftBtn), value 0
Event: time 1196621357.201492, type 0 (Reset), code 0 (Reset), value 0

So the first one I posted was probably the same kind of sequence
that leads to the unwanted double-clicks I'm reporting here.

This information may also be relevant:

The mouse is plugged into a USB2 hub, and appears as IRQ19:

 19:      34776          0   IO-APIC-fasteoi   uhci_hcd:usb1, ehci_hcd:usb5

Thanks. This definitely is bogus. In fact three clicks are reported.

Yes, this is correct.

Just a random shot into the dark -- if you remove the ehci-hcd module, 
does anything change?

No, just as jumpy as ever.

Right now it's double-clicking just about everything.
If I unplug/replug it, things behave for a while.

Still want the HID_DEBUG output?  (rebooting shortly)

Yes, definitely. I currently don't have an idea what might be causing it, 
and I am unable to reproduce it here.

If HID DEBUG doesn't reveal anything interesting, we would probably need 
usbmon dump too.

Okay.  I've got to leave the computer for a while now,
so I'll post again whenever I have something new here.

Leave it with me for now.  Thanks for helping!

Thanks. To sum up this longish thread:

- 2.6.24-rcX exposes the problem with sometimes multiple clicks being 
  generated as a response for one click on USB mouse (evtest shows that 
  really mutliple LeftBtn events arrive). 2.6.23 behaves correctly
- reverting the state of drivers/hid to 2.6.23 state doesn't make the 
  problem go away, so the problem is elsewhere (Input? USB?)
- Mark seems to be able to reproduce the problem quite easily; I was not 
  successful reproducing this no matter how hard I tried, and I also 
  didn't receive any similar bugreports from anyone else
- we are currently waiting for Mark to provide HID_DEBUG (and preferably
  also usbmon) output from the situation where multiple clicks are 
  being generated incorrectly

Well, I've rebuilt the kernel with HID_DEBUG, DEBUG_FS, and USBMON.
And I've written a nifty script to make usbmon tracing effortless for this.

And now I'm waiting.. things are currently behaving perfectly.
Go figure.  It did seem to arrive in bursts before.

So, don't beat yourselves over this one for now.
I'll track it down here and post again next time it starts happening.

Mmmm...

Okay, I'm having a problem with 2.6.24-rc4 that I didn't with 2.6.23-rc6.

When the problem hits, my mouse (synaptics touchpad) is randomly
moving about and clicking things whenever I have my finger on the
trackpad. This behavior will persists for five to ten minutes (is
happening now), and seems to be triggered by load (watching online
videos in flash player, for example -- this matches Mark's experience
with a make -j4).

I *think* the touchpad is connected via ps2, which looks like it'd
clear usb of any blame. It's /dev/input/event6 at any rate.

This has been happening about once a day, and seems to start because
of high CPU usage. ONce the CPU is idle, it still happens though, so
I'm not sure why it clears up.

Any clues for where I should hunt from here?

Can you try replacing drivers/input/ and include/linux/input.h from
2.6.23-rc6 and see if it works or not? That should give us idea if
input locking changes are to blame.

Thanks.

I'm hitting a number of build errors, trying to compile a hybrid
between the two.

git checkout v2.6.24-rc4
git checkout v2.6.23 include/linux/input.h drivers/input
make
# fails with kconfig issues
git checkout v2.6.24-rc4 drivers/input/misc/Kconfig
make
# fails
...adding to include/linux/input.h:
#define KEY_CNT                   (KEY_MAX+1)

takes the build a little farther until it dies on more missing
definitions. Doing a checkout of 2.6.24-rc4's include/linux/input.h
leads to different build errors.

Looking at git log for drivers/input, it appears the patches you're
talking about are the ones starting with 8006479c9b? If so, perhaps I
should just build the revision right before that commit and test that?

Are you really using mousedev and not true hid?
