Momentary freeze in Mac OS X on attaching a USB device This seems to have started only recently, but every time I attach a USB device or removable media (SD Card) to my MacBook Pro running OS X 10.8.3 the mouse cursor freezes for a few seconds. The screen is still updating. It seems to happen right when the OS sees the external drive (via phone, camera, SD card, etc.)

I don't see a spike in CPU or anything else suspect, just that the trackpad stops responding momentarily. What would cause this and is there a way to fix it?
Do you happen to have the Android File Transfer application installed? Various users on macrumors have noted the same issue, and have narrowed it down to having AFT installed.

I'm getting the same problem, and I too have AFT installed, but I won't be removing it any time soon as it's the only way to get anything to/from my Android devices.
