Jumping mouse problem solved

Hello! I just solved my jumping mouse problem following the instructions on this post: (I´m running a 10.6.8)

The instructions are as follows:

Possible fix for a jumpy gaming mouse on OSX

"...Additional googling lead to suggestions that you remove /System/Library/Extensions/AppleUpstreamUserClient.kext (Hint: Don’t remove it, rename it instead. See below)

cd /System/Library/Extensions/ && sudo mv AppleUpstreamUserClient.kext AppleUpstreamUserClient.kext.old

Now, normally, I don’t advocate that regular users mess with system files, but in this case, this “fix” actually worked for me. My advise is to rename that .kext file such that it is easily available if you ever need it, or if removing it causes problems. I would also advise that you not attempt this unless you have a way to restore it (dual boot OS, restore CD to access the file system, Time Machine, etc).

Anyways, the fix worked for me and the Jumpiness with my Logitech G5 is gone..."

What I did was make a copy of that file (just in case), and renamed the current one in the Extensions directory as suggested: AppleUpstreamUserClient.kext.old

I rebooted and It worked, no more jumping mouse.
