This is the strangest thing I've seen in the past 10 years of using computers. I have an Acer Aspire 7535-5020 laptop that came with windows 7, but I'm very picky and I wanted Windows xp back so I went onto Acer's website and downloaded all of the windows xp drivers and then formatted the laptop to Windows XP with intergrated Service Pack 3.

The computer works just fine except for one very strange oddity - the USB mouse I'm using only works when plugged into the first USB slot, it will refuse to work in the other 3 USB slots.

I'm using a Microsoft Intellimouse Explorer 3.0 USB which is my favorite mouse and I have 3 of them at home. When I was formatting the laptop, I had the mouse plugged into the first USB slot and now that is the ONLY slot it will work in. If I plug it into the other usb slots, the red laser will come on which means it's getting power, but it will not move the cursor and clicking either of the mouse buttons won't do anything.

When I have the Device Manager open, and I plug the Microsoft Intellimouse Explorer 3.0 mouse into the first USB slot, the 'Microsoft Intellimouse Explorer 3.0' entry will appear in BOTH the 'Human Interface Devices' tab and also the 'Mice and other pointing devices' tab.

However, when plugging the mouse into the other 3 usb slots, the 'Microsoft Intellimouse Explorer 3.0' entry will only appear in the 'Human Interface Devices' but NOT the 'Mice and other pointing devices' tab.

I could just go about my business using the first usb slot for the mouse, but this little strange problem is pissing me off hugely, as I might want to switch the mouse to another USB slot based on how I have the laptop positioned on a desk or other surface.

I should also note that the 'Human Interface Devices' tab has a 'HID compliant device' entry in it that isn't present on my desktop computer, and my mouse works on any of the 6 usb slots on my desktop computer. I wonder if this is the problem? I tried disabling this entry but it doesn't help any.

A final point to note is that I have many other usb devices such as flash memory sticks, camera card readers, external harddrives, gps devices, and they all work perfectly fine no matter which usb slot they are plugged into. Very strange indeed.

Is there anyway to make my mouse work in any of the other USB slots?

Try uninstalling the software required for the mouse and check if the mouse is still working, then plug into another port and install the software again. The other USB port might have a different speed or power consumption required for the mouse, try using another mouse and also check against the other USB port.

And/or, using the mouse working in it's USB port that works, go to Control Panel and uninstall it.
Plug it into another USB port and let windows discover it again.

Stupid question, but have you tried turning on the computer without the mouse plugged in, then inserting the mouse into one of the other USB slots with the computer running?

Also, you shouldn't need any software to run the mouse, so if that turns out to be the problem, just leave in uninstalled (I got tired of Intellimouse interrupting my games or movies to tell me my wireless mouse signal was low).
