I had the same problem on my MacBook. mouseemu is definitely the culprit. 
Instead of removing it though,
edit /etc/default/mouseemu and uncomment and change the last line to:

TYPING_BLOCK="-typing-block 0"

It appears mouseemu has a feature to disable the trackpad while typing. It 
seems to be mistaking an external mouse
for the trackpad because the mouse gets disabled but NOT the trackpad. Perhaps 
this is a usb device naming issue.
