Mac Mouse Malfunctions
« on: May 08, 2011, 02:43:41 pm »
I have an iMac which I dual boot with both Mac OS and Win XP. Once in a while my usb mouse will stop working, and I have to unplug it and plug it back in to get it working again. I've only ever had this happen when in Mac OS, so I don't think it's a hardware issue.

It's not a huge problem, more of an occasional annoyance. However, I'd still like to resolve the issue. I've tried looking online for answers, but the closest I can find is for an earlier version of Mac OS (like 10.3 or 10.4 or something.) Their recommendation was to update to the latest version. I don't think that's it though because 1) I had already have a version higher than what they were saying to upgrade to and 2) I have just updated to Snow Leopard (the latest version of Mac OS) and still have the problem.

Anyone have similar problems, and/or have any suggestions?

Does the problem appear when you start up in safe mode (holding down SHIFT just after the chime, and releasing after the logo appears)? USB device problems can be hardware or software, but it's easiest to test software and seemingly the port works normally under Windows. It's also possible that you have too many USB devices plugged in, or some other device is intermittently turning on and conflicting with the mouse.

Vararam,  plug another USB mouse into it and see if you have the same issue.

I think it's probably your mouse and not your laptop.

I've had this happen to me many, many times,  but especially with the mice I've used for laptops because i wrap the cable around the mouse itself to pack it up.  Sometimes you can see physical wear on the cable (check near the head,  especially,  if you're really curious) but other times it looks like it should be fine.


So yeah,  find another usb mouse to borrow,  or get a cheep one to test with.

By the way, this is not a laptop.  The mouse is a Microsoft optical mouse. Nothing fancy, but it's a good mouse that I've had for several years now. But like I said, the fact that I've never had this occur in XP makes me suspect it's not a hardware issue.

It only happens occasionally. So like, during a full day of use, it'll happen maybe 0 to 2 times. (so it not occurring is no guarantee that it's fixed.)

I've never tried the safe mode thing. Honestly, I didn't know that existed for mac. I know it's not the usb port itself 'cause it doesn't matter which one it's hooked to. Currently it's hooked through my keyboard, but it happens with it plugged straight into a port on the back as well.  I suppose it's possible it might be another usb device interfering somehow. Though I was unaware that devices plugged into other ports could potentially cause conflicts. Still, I can try keeping other stuff (other than the keyboard of course) unplugged for a while and see if that helps.

Edit to add: This is an issue that I've been having for months. Which is why I'm fairly confident from having never seen it in XP that this is not a problem with the mouse itself.

First of all, all USB mouses use the same driver (USB HID class), so plugging in another USB mouse won't help if it's a driver issue (which it surely is if the mouse works fine in Windows). My guess is that the mouse driver is seeing bogus input another (nonexistent) mouse, and is using it instead of your actual mouse. As far as actually solving this problem is concerned, I really don't any good ideas.

I suggested that before he mentioned that it worked in XP.   ^^;

I mentioned it in the original post. However, I still appreciate your trying to help.


I was thinking about the idea of another usb device possibly causing the problem, and I wonder if it could possibly be from the game controller. It doesn't happen very consistently though, and I commonly leave it (and a couple other devices) plugged. So...  I don't know. I'd think if it was a conflict from one of them, it'd happen more often.

Ah. My earlier post was based on the assumption that you don't actually have another device plugged in that can act as a mouse... Unplug it and see if that fixes it.

Ok, it's happened again. And the only devices connected where the mouse and keyboard.
