Logitech MediaPlay Cordless Mouse USB Linux driver

Installation

Kernel

First, confirm required support on your kernel source configuration file.
Open /lib/modules/your-kernel-version/build/.config and check for this lines:

Kernel 2.6

CONFIG_INPUT=y
CONFIG_INPUT_MOUSEDEV=y
CONFIG_INPUT_EVDEV=m

CONFIG_USB=m
CONFIG_USB_UHCI_HCD=m

Kernel 2.4

CONFIG_INPUT=m
CONFIG_INPUT_KEYBDEV=m
CONFIG_INPUT_MOUSEDEV=m
CONFIG_INPUT_EVDEV=m

CONFIG_USB=m
CONFIG_USB_UHCI=m

Notes:
• All this support can be compiled kernel builtin if you preffer.
• If your USB controller uses another host controller interface, replace CONFIG_USB_UHCI by the correct one.

If this lines are not present, add them.
Now, make sure CONFIG_USB_MOUSE and CONFIG_USB_HID ARE NOT kernel builtin (=y).

If you made any kind of change to the kernel configuration file, you should recompile (Kernel-HOWTO).
When all the required support is compiled, you can proceed.

Compilation

Get lmpcm_usb source tarball and uncompress it: # tar zxf lmpcm_usb-0.5.8.tar.gz
Now, change to the created directory, compile and install the driver: # cd lmpcm_usb-0.5.8
# make
# make install
Installation script installed lmpcm_usb.ko (lmpcm_usb.o for kernel 2.4) into /lib/modules/your-kernel-version/misc/ and added an entry to modules.dep file, using depmod.

Loading modules

Edit /lib/modules/your-kernel-version/misc/modules.dep and remove usbmouse and hid entries. This is required because these modules "steal" any kind of mouse, so we have to load lmpcm_usb first. If usbmouse and/or hid are required for any other device, just load them after lmpcm_usb. But don't forget, lmpcm_usb SHOULD LOAD FIRST that any generic mouse driver.
Loading support:

Kernel 2.6

# modprobe usbcore
# modprobe uhci-hcd

# modprobe evdev

Kernel 2.4

# modprobe usbcore
# modprobe usb-uhci

# modprobe input
# modprobe mousedev
# modprobe keybdev
# modprobe evdev

Notes:
• If your USB controller uses another host controller interface, replace uhci-hcd (or usb-uhci) by the correct one.
• This lines should be added to your rc modules script to provide usb mouse support before applications start.

Ensure usbmouse and hid are not loaded:

Kernel 2.6

# rmmod usbmouse
# rmmod usbhid

Kernel 2.4

# rmmod usbmouse
# rmmod hid
Load lmpcm_usb module: # modprobe lmpcm_usb
At this time, your mouse should work.

Testing

To check if your mouse was successfully detected, perform these commands:
# dmesg | grep '^lmpcm.* usb'

You should get something like this: lmpcm_usb.c: Logitech MediaPlay Mouse on usb1:4.0 [Logitech USB Receiver]: input0
If you got nothing, that's because your mouse was not detected by lmpcm_usb kernel module. Maybe you have no USB support or HID is loaded and "stealing" mouse device.

Check your multimedia buttons by running:
# hexdump < /dev/input/eventX
   (where X is the mouse event device number)
Press and release play/pause button, the result should be similar to: 0000000 d0c8 4287 1e3b 000e 0001 00a4 0001 0000
0000010 d0c9 4287 6c1a 0001 0001 00a4 0000 0000

Configuring X server

Edit the X server configuration file (/etc/X11/XF86Config for XFree86 or /etc/X11/xorg.conf for X.org) and change it to match this configuration: ...
Section "InputDevice"
  ...
  Option "XkbModel" "pc105"
EndSection

Section "InputDevice"
  Identifier "LMPCM"
  Driver "mouse"
  Option "Protocol" "ExplorerPS/2"
  Option "Device" "/dev/input/mice"
  Option "ZAxisMapping" "6 7"
  Option "Buttons" "7"
EndSection

Section "ServerLayout"
  ...
  InputDevice "LMPCM" "CorePointer"
EndSection

Notes:
• If you preffer to add Logitech MediaPlay Mouse as a secondary pointer device (example: for laptop computers), just replace "CorePointer" with "AlwaysCore".
• Dont's forget to restart the X server after changing configuration file.

Download Xmodmap-2.6 (or Xmodmap-2.4 for kernel 2.4), move to your home directory, set LMPCM as main pointer device (if you have more than one) and load it:

Kernel 2.6

$ mv Xmodmap-2.6 $HOME/.Xmodmap
$ xsetpointer LMPCM
$ xmodmap $HOME/.Xmodmap

Kernel 2.4

$ mv Xmodmap-2.4 $HOME/.Xmodmap
$ xsetpointer LMPCM
$ xmodmap $HOME/.Xmodmap

Configuring applications

Gnome

Gnome have a simple and quick interface to configure shortcut keys, but unfortunately it just supports a few number of operations.

Assuming you have Gnome-2.10, on your higher panel, click on "Desktop" menu, choose "Preferences" and "Keyboard Shortcuts".


Choose an event from event list and press the button you preffer.


Done :)

Kde

I think KDE have an almost perfect shortcut management system. It's very simple to configure shortcut keys on any application and operation. Anyway, the only thing I couldn't get working here was the Left blue Back/Forward browser buttons.

Assuming you have Kde-3.4, on your bottom menu, click on Konqueror web browser icon.


Type "settings:/Accessibility/" on the location bar.


Click on "Keyboard Shortcuts" icon, this will show you a very complete shortcut management interface. Choose an action, click on the button-like image, press the button you want to assign and click "Ok".


Done :)
