Ok, this is the Readers Digest condensed version of my problem...if you require more details, please ask: I recently upgraded (?) to Panther. Before the upgrade I was running an iBot web cam from my Quicksilver 933 DT without a hitch. After the installation the cam would no longer work. I took it to my PowerBook where it had previously worked (and had also been upgraded to 10.3.2) and it would not work there either. I wrote to Orange Micro where some rocket scientist in the tech dept told me it was the camera. In desperation, I bought an iSight and plugged it into my PB and used it without incident for a couple days. On the third day I decided to plug it into my DT and it would not work...took it back to the PB and it quit working there. Replaced the iSight and plugged it BACK into the PB where it is working fine. Upon further research and computer maintenance it appears that neither of the firewire ports on the G4 are working. (internal) Not only are they not working but they fried two cams. My question is : Has anyone else heard of/experienced this and is there a fix for it besides the dreaded ship-the-computer-away-for-an-expensive-revamp? Help!
