Do you use udev? If not there might be an event device missing for your
usb mouse in /dev/input/. With the attached program you could check, if
there is a proper device. (Compile with gcc -Wall -o cev cev.c, run as
root because access to the event devices is needed.)

If no event device is available you have multiple choices:
1. install and run udev
2. create missing devices by hand with mknod 

Pbbuttonsd will automatically recognize newly attached devices only if
it was configured with autorescan = yes. See the man page for all
details.
