Misdetection of Logitech Mouse M-BA47 as ExplorerPS/2

Could you please test this on Feisty or newer, and attach your /var/log/Xorg.0.log file?

Just tested with feisty live CD: seems to work there.

On edgy I just noticed that when dpkg-reconfiguring xserver-xorg, even when I selected ImPS/2, there was always ExplorerPS/2 written to xorg.conf.

Seems to be resolved though.

Thanks for the confirmation that it's fixed in Feisty. Closing as such.

At this moment the default xserver-xorg debconf template in Feisty always manually configures a mouse with these options in /etc/X11/xorg.conf:
       Option "Device" "/dev/input/mice"
       Option "Protocol" "ImPS/2"

Normally Xorg should be able to autodetect the protocol of a PS/2 or USB mouse using /dev/input/mice by putting protocol to "auto", can you try this.

It would be nice if you could provide the following information:
1. How is your mouse connected to your PC: serial, PS/2, USB, USB wireless, ...
 For a USB mouse include the relevant output of the command lsusb on a terminal.
 What mechanism does your mouse use: ball mouse, optical, trackball, ...
 How many physical buttons and scrollwheels does you mouse have?
2. Open /etc/X11/xorg.conf and change the mouse protocol to:
      Option "Protocol" "auto"
3. Restart X with Ctrl-Alt-Backspace.
4. Provide the output of the following command on a terminal:
 $ cat /var/log/Xorg.0.log | grep -i "configured mouse"
