Subject: 2.6.28-rc9: USB Mouse unhappy

Just installed today's git on my workstation and my Logitech USB Mouse
only wants to move vertically around the centre of the monitor.

I have no clue where to look - all I know is that it works with the
2.6.27 and various 2.6.28-rcs prior to this one.

Could be input, could be HID, could even be USB.

You're sure that 2.6.28-rc8 was OK?

2.6.28-rc9 had only a small number of changes. Nothing I can see in
input or HID. A few USB changes, but pretty specific ones -
unusual_devs entries and such.

Maybe your mouse has died? Did you retest with an older kernel?

Nope - not sure about 28-rc8. I meant to say some previous 28-rc's
that I tested worked fine - can't recall which ones. it is likely I
missed testing .28-rc8.

I did - rebooting into 2.6.27 (original distro kernel) makes it work again.

This sounds to me like 'usbmouse' gets used instead of 'usbhid' on
2.6.28-rc9. Many users have reported only vertical movement with
'usbmouse'. Better check the kernel configuration, if you had usbmouse
disabled in 2.6.27, then disable it with 2.6.28-rc9 as well.

Sure enough - rmmod usbhid; modprobe usbmouse reproduces the exact
same problem on a working kernel.

But the thing is I use the same base configuration across all kernels
I build (sans of course the newly added config options) - so something
changed somewhere and now usbmouse gets used instead of usbhid.

What's the deal with usbmouse though - is it supposed to be working or
is it considered lost cause in favor of usbhid? May be if people don't
need to use it and it is not actively looked into, we can
disable/remove it?

Thanks

Could you please provide vendor and product IDs of this device? (lsusb -v

Could you please

- make sure whether usbhid is used on 2.6.27 to drive the mouse and
usbmouse on 2.6.28-rc with the exact same mouse? (either check
/sys/bus/usb/devices or even lsusb shouldn't ideally show usbmouse
loaded at all)
- if so, make sure that you really need to build usbmouse (please read the
help text in Kconfig for explanation)

Really, please read the help text.

Maybe we should make it dependent on EMBEDDED.

Sorry for the above typo, 'lsusb' should of course be 'lsmod' here.

So do I get it right that the only reason of the problem you were seeing
was that in the 2.6.27 kernel you have compiled usbhid module, which was
then used for driving your mouse,but in 2.6.28-rcX you compiled and used
'usbmouse' instead, and therefore this is not a regression?

Shouldn't usbmouse support two-dimensional mice as well?

Yup, but that's a separate issue on my TODO. I first want to know whether
this is a regression or not.

I have always compiled usbmouse as a module - the problem or regression
here was that it was loaded instead of usbhid when both were compiled as
modules - but I don't think this is a kernel regression, here is why -

The problem happened with Fedora 10 - when I booted into Ubuntu 8.10 with
the same kernel compiled with same config, usbhid was correctly loaded and
mouse worked. So I would forget this as a Fedora specific issue.

Thanks for the pointers.

It may well be that Ubuntu has usbmouse blacklisted or employs udev
rules that force usbhid to be loaded before usbmouse.

On Mandriva it was handled in a similar way, before usbmouse was
disabled from the kernel (no reason to have it in a "normal" kernel).

Right - Ubuntu blacklists it and it works. Fedora doesn't blacklist it but
it is not a problem with the distro shipped kernel - somehow. The problem
happens only when using vanilla kernel on Fedora - not sure what's going
on there.

Yep, and so the patch to make it dependent on EMBEDDED still makes sense.

Do they even compile usbmouse and usbkbd?

Turns out they don't (and I thought all distros ship make allmodconfig
kernels for some reason) - now I will be puzzled for ever as to how did those pre rc-9
kernels worked without usbmouse being blacklisted. Might be config, might
be timing, dunno.

Parag was using incorrect driver -- usbmouse -- (which is intended to be
used only under very special circumstances) instead of standard HID
driver.

Kconfig help text clearly states how special the usbmouse driver is, but
many people still try to use it, probably because of its name. Therefore
we now have

Author: Parag Warudkar <[email protected]>
Date: Mon Dec 22 22:50:52 2008 +0100

HID: make boot protocol drivers depend on EMBEDDED

which is already in Linus tree and which makes the possibility of chosing
this special driver dependent on CONFIG_EMBEDDED.

Wasn't a regression - for some reason USB Boot Protocol drivers for
mouse and kbd were compiled and loaded - I sent a patch to Jiri making
those depend on EMBEDDED - so no more an issue.
