Did you by chance also upgrade udev? udev has recently decided to take 
over the job of hotplug, but the upgrade is not seamless. See here:

http://sourceforge.net/tracker/index.php?func=detail&aid=1353514&group_id=87777&atid=584353

My own rule looks like this:

ACTION=="add",SYSFS{modalias}=="usb:v0763p1014d0001dcFFdscFFdpFFic*isc*ip*",RUN+="/usr/local/sbin/midisport_fw"

For more on what's going on, google for "udev hotplug firmware".
