Belkin USB PCI not functioning.
I don't know when, if after any updates this has stopped working. I can't seem to find much information about updates to the firmware because of tiger or anything. There was this, I installed the last one to no avail; http://en-us-support.belkin.com/app/answers/detail/a_id/541/~/f5d5055-gigabit-us b-2.0-network-adapter---driver

Not sure what other info is relevant.
