I currently update my computer to 10.4.9 and read that it includes support for USB webcams in ichat specifically USB Video Class (1.0 I assume). However when I hooked up my Lenovo USB webcam hoping to see if I could do a video chat with friends, it didnt work. However it uses the newer Vmicro VC0321 controller that supports USB video class 1.0, thats why I am wondering why it isnt working? any thoughts on that?
I updated 3 computers with 10.4.9 using Software Update -- an old PowerBook G4, a dual G5 and an Intel iMac -- and iChat isn't connecting anymore on any of the computers. I'd love to know if there's a fix.
This suggestion might not fix the problem, but I never use the "Automatic update" for O/S upgrades. This is an "incremental update that only inserts changes into to your O/S files. I recommend you run "Disk Utility" to repair permissions, then download the 10.4.9 Combo installation file which is about 163Mbytes. This "update" effectively replaces your entire O/S with a fresh copy.
The thread subject references "10.4.9 ichat update not working?". I responded to Mark Block and hienqnguyen. They talked about problems with iChatAV after the upgrade. I felt it was only courteous to do so.
I too am having this problem with all my Macs: my MacPro, My MacBook Pro, and my iMac Core Duo after 10.4.9 installed. I can no longer video chat. I tried it within my own network, outside of my own network over the Internet, and many other networks.
I think I may be having a simmiler problem. I have an ibook g3 900 and I get a black preview screen with my xbox 360 web cam. Quicktime, iMovie, photo booth, mirror (dashboard) all get the black screen or an error message. I noticed this in the log:

It appears that many folks are having issues w/ichat after 10.4.9 update.
I have already done the full 10.4.9 download and re-applied the full update plus I did the disk-utility option that repairs permissions and ichat is still hanging.
I also installed ichat from the original DVDs which allows me to connect occasionally without hanging.
Is there a way to "rollback" to 10.4.8? I'm a newbie w/Macs and outside of wiping my machine and starting over, I don't know another way.
I have the same issue after updating, I cannot even GET a video from someone else on Ichat now, so not only does my camera no longer work, I can't see anyone else either!! I can only text "chat". I did a reinstall of quicktime, I have done all the obvious fixes, nothing helps. I hope the folks at Apple see this and fix it FAST!!!
