Test on another Mac if possible. You may also need to test different cables and or adapters.
(2) If your 10.9.2 Mac's System Information utility still doesn't recognize your Firewire iSight:
Apple discontinued external iSight several years ago. My external iSights (I have two) are great webcams, but they are getting old as consumer electronics go. Both of mine still work as well as they did when they were new. However, some previously owned or even NOS (new, old stock) iSights may have been damaged by rough treatment or improper storage.
An honest seller may offer you return or exchange privileges. If not, and if you don't want to spend the money to have your external iSight serviced, consider a new, Mac-compatible USB cam instead.
A new cam will include a current manufacturer's warranty, and a USB cam is not subject to the possible conflicts that can cause difficulties with the old Firewire-connected iSights.
