| Binding + and - in Logitech G5 mouse | |
| If you want to bind the buttons + and - in G5/7 mouse, which normally changes DPI, you have to use g5hack [2] released by a lomoco author. | |
| wget http://piie.net/temp/g5_hiddev.c | |
| gcc -o g5hack g5_hiddev.c | |
| ./g5hack /dev/usb/hiddev0 3 | |
| This will change your DPI to 2000, light the 1st LED and disables DPI on-the-fly changing, so you can use it with evrouter. If you would use it frequently I suggest you to copy it to the /usr/bin directory: | |
| # cp g5hack /usr/bin/ | |
| If you want to bind your + and - buttons you must copy the line at the bottom (one with the comment '"-" button does not function anymore' above) to the mode you will be using, like, for example, under the "case 3:" you can put it on the line with the comment 'turn on third led' above (deleting the old one before of course). | |
| For the newest G5 mouse which is reported as "product 0xc049" original hack does not work. You have to simply change the #define MOUSE_G5 0xc041 to #define MOUSE_G5 0xc049 and recompile. | |
| You can execute the g5hack tool at system start up using systemd unit. See Systemd#Writing unit files for detail. |

| * Additional Info: | |
| * | |
| * the g-series has two modes: | |
| * | |
| * 1. mode: no driver | |
| * in this mode there is a list of resolutions implemented in the mouse | |
| * and you can switch between them using the buttons | |
| * | |
| * 2. mode is: windows driver | |
| * in this mode the buttons talk to the driver | |
| * they have absolute no effect on the hardware in first place | |
| * the driver gets the button event looks in its table, which resolution to use | |
| * sends it to the mouse sets the leds and the resolution | |
