Mouse scrolling too fast

The best thing about Microsoft are their mice (mouses), I love them. The tracking acceleration seems so natural while Apple’s is rubbish, for me at least. That’s why I use the Microsoft Wireless Mobile Mouse 3500. Cheap as chips and works perfectly in every way … but one. Scrolling is way too fast.

No matter how much adjustment I did it’s still way too fast. I set the Vertical Scrolling Speed in System Preferences (under Microsoft Mouse) to a minimum but it still scrolls like 15 lines with one wheel click (those little clicks while scrolling the mouse wheel).

Lucky I had a spare wired MS mouse to compare them. The wireless mouse USB dongle is plugged in one USB port on my external monitor (Dell U-2410), the Apple wired aluminium keyboard into another one while third one is free for my camera’s cable when needed. The monitor’s internal USB hub is then connected to the computer (MBP) via another USB cable.

I plugged the wired USB mouse into the USB port on my keyboard and the scroll on that mouse worked fine, slow as. I took it out and plugged into the spare USB port on the monitor and the scroll went crazy. I thought it might be conflicting with the dongle, so I took the wireless mouse dongle out, but the wired one still acted crazy. The last option was to plug in the dongle into the keyboard’s USB port and guess what – it works perfectly fine.

So if I plug the dongle into the USB port on the monitor – the scrolling is super-fast. If I plug it into the keyboard, which is connected through the monitor anyway, the scrolling is perfectly fine. I have no idea why, but it works.

    Finally! I’ve been looking everywhere for a solution to this problem!

    I have the new MacBook pro, and I myself have the Microsoft Mouse 3500. I had the same problem of it scrolling like 20 lines when I only wanted one! But when it did that, I had my receiver in my USB port on my mac.. and after reading this, all I did was take out my receiver and plug it into a USB hub that is still connected to the other USB port on my mac.. and now it works fine. I also have no idea why this happens, but thanks for the tip!

    I was having trouble with this and Googled it. Thank you for posting this blog. Your tip worked perfectly for me! Heck, I didn’t even realize the USB ports on my wired keyboard could be used for other devices. Thanks again for the advice!

    Finally an answer! I couldn’t believe the solution was THAT stupid! I just thought “yeah, right”, but then I tried it. I have a Macbook and moving the dongle to another usb port actually fixed the scroll problem.

    I had the same problem on my Asus laptop. Inserted the USB receiver into a different port and it’s working fine now! Weird bug.

    Fantastic. Very intriguing issue. I use a MacBook Air mid-2012 and a Microsoft Arc Mouse Touch. The only downfall to the MBA is the lack of USB ports (though the fact that the two existing ones are high-powered USB 3.0 is nice), so I use a USB 2.0 4-port hub. After restarting between OSs my Arc Mouse’s scrolling was hyper jumpy– but just switching the receiver to a different port on the same hub solved the problem.

    Thanks for the tip, Mike, it does work! And I have confirmed replacing the 3500 dongle back to the USB port where it first plugged in will also work.

    I could not disable horizontal scrolling but I set it to 1 and it helped. Changing the usb ports did not. I have an ASUS Aspire and Microsoft mouse.

    Hi. Separate issue but can’t find any better place to post for help. Have you been able to get the wheel button to work with OSX? I’ve installed the Microsoft Mouse 8.2 application but OSX doesn’t recognize the configuration… Cheers!

    I have a hackintosh recently upgraded to Mavericks and have been searching for cure for the fast scroll ever since.
    You are the only place I have seen a cure for this.
    My mouse was plugged into a hub. I plugged it into the computer and happiness now reigns supreme.
    Thank you.
    You are a god among men.

    Thanks for your post! I had the same issue. Today I deleted the Microsoft software for the mouse, this resolved the problem completely. This software modifies the scrolling behavior. With the same amount of lines configured, scrolling goes much faster.

    I’ve found that unplugging the usb dongle and plugging it back in corrected any erratic behaviour. I didn’t really need to switch ports. But thanks for posting!! Worked great.
