I'm currently using logitech's mouse, but setpoint software with which you customize your mouse functionality is pretty bloaty and has its bugs, couple of days ago I've found a thread on other forum, content was actually ported there from here ( although I couldn't find original thread here )

Here's the tutorial


I found this over at es reality
I tried it on my mx300 an I am loving them
they have a nice bit of software for setting your x y speeds etxc, imo there very good

but its up to you I guess
props to dickobrazz's from ES for posting this

1. Download the latest Razer drivers here (http://razer.tigga.org/download-xp.php) .
2. Download the modified INF file, and place it in your C:\Program Files\Razer\Drivers. Make sure you delete the old Razer.inf file, before placing the modifed INF (http://hexxxen.port5.com/Razer.inf.zip) file in the directory.
3. Now go to your device manger, by pressing Control and the Pause Break keys on your Keyboard, or by going to Start > Control Panel > System > Hardware > Device Manager.
4. Assuming that you have the Logitech mouse installed in either the USB or PS/2 connections (I reccomend USB and also the Razer drivers are USB recommend), navigate to the Mice and other pointing devices, and update the device that you see, like Logitech USB Wheel Mouse. Now once you're in the update driver prompt, choose the option called "Install from a list or specific localtion". Once that option is choosen, click on the option called "Don't search. I will choose the driver to install". After that, now click on the "Have Disk..." option, and it will prompt you to search for the a driver. From the "Install From Disk" option, Choose "Browse" and then locate where the modified Razer.inf file is, where I told you to place it, which is located at C:\Program Files\Razer\Drivers and choose the Razer.inf file. Now it should prompt you to install a device driver name called "Karna USB Mouse". Choose the option to install that driver, and click on the "Next" option. Now that the driver is installed, reboot Windows. Now you should be able to use Razer's configuration software.

The question is, what will I benifit uppon using these drivers from Razer, with my Logitech mouse? Well for these following reasons:

1. Razer drivers aren't buggy, compared to MW.
2. Razer's drivers doesn't install and modify registry settings that will mess up Windows, such as Mouse Acceleration and other mouse settings, that aren't pleasant.
3. Razer drivers are bloat free, it only installs the system driver, and using it's own mouse configuration software to colaborate the mouse settings.

Now a final question that you're wondering. Now the Razer drivers are designed to give a Razer mouse product at a 2000DPI rate, where'as we are using a Logitech mouse, for example, an 800DPI model. I'am sure that these Razer drivers wouldn't give you a 2000DPI configuration, because the mouse we're using can only handle an [800DPI rate. I guess these drivers will enable a Logitech mouse product with an 800DPI setting automatically. Tho I'am not 100% sure, but if it's true, then you'd rather use Razer's drivers, instead of MouseWare...




Now the thing is, link for modified .inf file hasn't been working for some long time I suppose ( http://hexxxen.port5.com/Razer.inf.zip ), if anyone could reupload it, I would be very grateful.
