I have a Microsoft Wireless Mobile Mouse 4000 and a mid-2012 Macbook Pro (non-Retina). I normally have a lot of USB devices that I need to have plugged in so when I got my Macbook Pro I just continued to use my mouse plugged into my USB hub along with my other devices. But recently I was out somewhere and I just wanted to bring my mouse along with me and when I plugged the wireless dongle straight into the usb port it wouldn't recognize my mouse. I messed around with settings and tried to reinstall the drivers but that didn't work. When I got home I plugged it back into my USB hub and it worked. It's not really a big inconvenience but it's kind of strange and I'd like to fix it. Has anyone else experienced this or know of a solution?
I have a brand new mid-2012 Macbook Pro i7 15", which I bought on 12-23-2012. I was using my bluetooth mouse but the secondary button wasn't working accurately in one of my applications, so I switched to my trusty Microsoft Wireless Mobile Mouse 4000. When I plugged the dongle into the USB 3.0 port, I got an error that said my laptop keyboard needed to be identified (?!). I couldn't get it 'identified' until I turned off my Bluetooth option. When I did that, both the mouse and the internal keyboard played nice.
