A while ago I installed the Logictech Control Center so that I could use my old Cordless MouseMan Optical on my iMac. I missed the convenience of wireless, but more than that, I no longer could successfully clean the scroll ball on my Mighty Mouse (which has always been its main attraction for me).

But although the MouseMan worked nicely, and its wireless nature was extremely convenient, I did miss the MM’s scroll ball, so I stopped by my local Apple Store, and they decided to replace the MM (I purchased my system less than a year ago).

After plugging in the new MM, I discovered that it worked independently of the MouseMan. So I then had both mice (mouses?) to work with.

Subsequently, while performing routine maintenance, I rebuilt my internal drive's directory via TechTool Pro as well as DiskWarrior. That seemed to improve the iMac’s performance a bit, but I then discovered that the 3rd and 4th buttons on my MM no longer worked. I checked the Mouse prefs, and they were still at their default settings. I played with settings to see if assigning new functions to the 3rd and 4th buttons would make a difference. It didn't. I replaced com.apple.driver.AppleHIDMouse.plist and com.apple.systempreferences.plist with the ones on my SuperDuper! drive, but that didn't help either. However, when I booted from the SD! drive, the MM worked perfectly.

During all of this, I had downloaded and installed both USB Overdrive and SteerMouse, to see if I'd prefer their acceleration curves to MM's (which I find painfully annoying). However, I initially didn't, and since I didn't want to spend a lot of time trying to configure their settings to my satisfaction before making a purchase decision, I uninstalled them (I used AppZapper and AppCleaner to make sure that they were completely uninstalled). It certainly seems that the the act of installing and uninstalling USB Overdrive and SteerMouse somehow caused the partial disablement of my Mighty Mouse, but I don’t know how, nor what to do to restore its full operation.

Any ideas?

I would reset the NVRAM/PRAM and if that doesn't work, I would unplug all the USB devices, power down the Mac, take the battery our, leave the computer off for a couple minutes, replace the battery and then reboot the Mac.

If the Mighty Mouse was a wireless model, you may also have to delete the ~/Library/Preferences/com.apple.Bluetooth.plist file.

Blatantly obvious but I guess no Logitech software is present there and the Logitech mouse is disconnected (off).

Nah...it's the standard wired mouse.

Take a look inside your /System/Library/Extensions and see if it contains a Logitech kernel extension.

Yes, there is one with the name 'LogitechForceFeedback.kext' but I guess it is there by default with an OS X installation since while I am using a MX Revolution I haven't installed any Logitech software, I am running SteerMouse instead.

Yup...Apple began to include it a few OS versions ago.

... since while I am using a MX Revolution I haven't installed any Logitech software, I am running SteerMouse instead.

As I said initially, I had tried USB Overdrive and SteerMouse, but decided to postpone any decision regarding which I preferred, when all of my problems began. But before installing them, I was running the Logitech LCC with my MouseMan at the same time I was using Mighty Mouse, and I had no problems. I will download them and re-install them, and then uninstall them all over again, to see if (somehow) that will clear things up. (I don't know what else to do, short of an A & I or clean system re-install.)

What made you go with SteerMouse? Did you try USB Overdrive? My semi-ideal setup would be to have both my MouseMan (for its wireless convenience) as well as my Mighty Mouse (I really like the scroll ball) running at the same time. But if I could "fix" the Mighty Mouse acceleration curve, I might just stick with that. I've heard that both Steermouse as well as USB Overdrive enables some tweaking of the acceleration curve, but I don't know which is supposed to do a better job. Any opinions?

No, I haven't tried USB Overdrive so truth be told I can't say what makes SteerMouse a better or worse option then USB Overdrive. I just went the SteerMouse route due to friends feedback. No buyer's remorse though.

Well, I (again) downloaded, installed, and then uninstalled both SteerMouse and USB Overdrive. For whatever reason, that little exercise seems to have "fixed" my problem: The Mighty Mouse (as well as the MouseMan) now is fully functional.

What I woud like to do now is see if there's a way of modifying the Mighty Mouse's acceleration curve so that the Mighty Mouse "behaves" better. Do you know if that can be done with any settings in SteerMouse? If so, I'll reinstall it. (Not sure if I should uninstall Logitech's LCC, though...I don't know if there''s an inherent conflict between it and everything else!)

AFAIK all you can adjust with SteerMouse regarding the mouse pointer is done here:



Then, it could include some tips about the Mighty Mouse, if so all you would have to do is clic on a (Tips…) button which is under the (Wheel) section. With the Logitech MX Revolution it lets you adjust the kind of wheel behavior which is done with the Terminal app… just a line of text. It may have some 'hidden' adjusts or the Mighty but in all honest I don't know for sure.

Huh? I don't see a "Tips..." button under the "Wheel" section.

Arg sorry, it is under the Buttons section, my bad. I haven't tried it with a Mighty Mouse so I don't know if this is a MX Revolution only thing or it is there by default no matter the mouse.

I still have the Logitech LCC installed, and I don't see a "Tips..." button. Instead, I see a "Error Info..." button which, when I click on it, brings up a dialog saying that if I have problems with my mouse, I should uninstall LLC:





I'll have to uninstall LCC to see what (if any) button replaces the "Error Info..." button.

Well, I uninstalled LCC, and ended up with SteerMouse's default buttons setting (there is no "Tips..." button):





But I was able to find a combination of cursor Tracking Speed and Sensitivity settings that pretty much "fixed" the Mighty Mouse's horrid acceleration curve:
