Re: 2.6.28-rc9: USB Mouse unhappy

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.

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)

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?

Really, please read the help text.

Maybe we should make it dependent on EMBEDDED.

Thanks,
