Is moused enabled or not?  I just committed a patch to HEAD to enable
O_ASYNC on psm.  I started to fix up usb as well, but couldn't quite
figure out usb2 to find where to send the signal...  So, if you are not
using moused, this may help.

Are you using the synaptics driver? or generic mouse driver?
