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.
