some Logitech Cordless Desktop Optical keys act as mouse buttons

[nanophase]

Messenger/SMS key acts as mouse1 (left)
Webcam key acts as mouse3 (right)
iTouch key acts as mouse2 (middle)
pressing the wheel (yes, on the keyboard) doesn't doesn't generate anything in xev at all

I never had them working on Linux yet, might be a driver issue. All other extra keys work nicely.

This is caused by the keyboard itself. I have two devices that register multiple input device entries, one a Logitech keyboard. In the dmesg output, the keyboard is listed as follows:

[ 39.634648] input: Logitech Logitech USB Keyboard as /class/input/input3
[ 39.634652] input: USB HID v1.10 Keyboard [Logitech Logitech USB Keyboard] on usb-0000:00:02.0-8
[ 39.654653] input: Logitech Logitech USB Keyboard as /class/input/input4
[ 39.654746] input: USB HID v1.10 Mouse [Logitech Logitech USB Keyboard] on usb-0000:00:02.0-8

    In my case, the keyboard wheel generates mouse buttons 4 and 5, fed into xev through /dev/input/mice multiplexing, although clicking the keyboard wheel doesn't seem to have any effect.

    The package `input-utils` [dapper only] allows easy investigation of input devices, and includes lsinput, which clearly shows the internal configuration.

Good call, here's my dmesg output grepped on "logitech", just in case:

[4294677.777000] input: USB HID v1.10 Keyboard [Logitech USB Receiver] on usb-0000:00:07.2-1
[4294677.812000] input: USB HID v1.10 Mouse [Logitech USB Receiver] on usb-0000:00:07.2-1
[4296668.092000] input: USB HID v1.10 Mouse [Logitech USB-PS/2 Optical Mouse] on usb-0000:00:07.2-2.2

Same with the Logitech iTouch Internet Navigator Keyboard SE connected to an USB port. This problem doesn't occur if connected to a PS/2 port.

I tried my Logitech Cordless Desktop Optical with an USB->PS/2 adapter, I have the same effect as on USB, except that 3 multimedia buttons that act as mouse buttons 1-3 with USB, don't do anything with PS/2.

Can you try setting up these keys in the Keyboard Shortcut utility? Are they separate keys from the mouse's buttons?

[nanophase (nanophase)]

Nope, they really act like the mouse buttons, so pressing the one that acts like mouse_button_1 enters/exits edit mode. They behave 100% like mouse buttons. They never generated any keycodes, not in X, not outside, never. Let me know if I could test anything.

I think this issue is long since fixed. If it still occurs in Jaunty when using xserver-xorg-input-evdev, please feel free to open a bug about it against that package.
