Conflict! – Mac OS 10.4.8 (Intel) and Logitech Control Center 2.11

This weekend I reloaded our Intel powered iMac with OS X and then transferred my wife’s user data from her G5 1.8 GHz iMac to it. As part of the software reloading process, I ran Software Update and one of the packages it pulled down was the new Mac OS 10.4.8 Combo Updater. That all seemed to go fine. I didn’t see any problems with the machine.

Yesterday was the first day my wife interfaced with her university’s Windows-centric network, and her mouse started locking up. She is using a USB-connected, blue Logitech MX510. The mouse has always operated without problems until now. The mouse cursor hung, and I had her try to use the keyboard to call up the “Force-Quit” dialog, something she was able to do. When that worked, I knew the problem centered around the mouse and not everything USB. While I thought I had downloaded the latest Logitech control center, a Universal Binary, last night, I talked her through a download of the software again. It is Logitech Control Center 2.11. I had her run the Uninstaller, reboot the iMac, and then run the Installer. The problem came back. I asked her to Uninstall the software. The problem disappeared when Logitech Control Center software was removed.

Interestingly, I am running this same software (Logitech Control Center 2.11) on my G4 and G5 powered Macs and am not seeing any problems there, even with the 10.4.8 update. Whatever is causing the problem seems to only affect Intel-powered iMacs.

I’ve tried uninstalling and reinstalling the software; but, days after, we’re still seeing the mouse hang up occasionally. I’m not seeing comments on the ‘Net about this being a widespread problem, so I’m unsure what’s causing it. I’m going to try reinstalling the 10.4.8 Combo Upgrade and see if that helps. If not, I’ll have to give my wife the options of uninstalling the Logitech software until it or OS X is updated or cycling her mouse by unplugging it and plugging it back into her keyboard every time it happens, which fortunately is not that often.
