Hi,

I have been looking at my mouse problems in XF 3.9.18 and put some debug
statements into Xserver/hw/xfree86/input/mouse/mouse.c to look at the raw
characters being read from /dev/usbmouse.

They seemed to pretty much be garabage and out of sync.  Sometimes the head of
the character buffer showed mouse button events and sometimes other buffer
positions showed the events.   Also, the mouse.c driver tries to read 4
characters from the usb mouse while the Xpmac mouse driver I wrote only reads 3
bytes at a time.

So the IMPS/2 protocol is just getting garbage to process into buttons, and dx,
dy, dz.

Is this a known problem?

  There were some changes recently in the mouse module in xfree, some PS/2
mice were broken for a while but that has been fixed before 3.9.18, I don't
a usb mouse at my mac so i can't help there but IMPS/2 works fine in my x86
machine.

I looked back to xf3.9.17 and it defaulted to my legacy mouse driver but xf
3.9.18 won't seem to do that  (the mouse module is forcibly loaded by XFree86
Xserver whether you want it to or not).

  I am not sure but i think that 3.9.17 was using the same code as well,
probably one of the changes in mouse.c broke something. Is it IMPS/2 the
right protocol for the ppc usb mice btw ? If our usb code uses 3 bytes
then its not using the IntelliMouse protocol (which is 4 bytes as i can
see in the code).

Any ideas here would be greatly appreciated?

  Can you try with the other PS/2 protocols and if you still can't get
the mouse working try with older mouse code from 3.9.17 that will help
tracking down the problem.

Has anyone been able to get a usb mouse working with xf 3.9.18?

Thanks,

Kevin
