I did some detective work today. I do have a Device Keys folder  
containing what appears to be a key file. The mystery files are in  
addition to this and have different names, alternating alphanumerics  
and % signs, like %BF%FFް%BF%FF%DFX%BF%FF޸%A0nl. I did an experiment  
which might help: I drop then in the trash but am unable to empty  
trash because these files are in use; however if I quit the "IOXperts  
Session Monitor" process using Activity Monitor, the files are no  
longer in use and I am able to empty trash. So they seem to be owned  
by that process. As soon as I relaunch it (ioxsessiond app inside / 
Library/Application Support/IOXperts/Private/ ) another one of these  
files is re-created.

I've been using QuickTime Player --> New Movie Recording to monitor my  
cam. HackTV is a faster way to get the cam going, thanks for that.

I think they appear on boot, and my explanation above seems to have  
outed the culprit -- I hope?

Not sure I want to try that!

Good call, I was able to get HackTV working with the QuickCam and  
QuickTime Player running the other cam. However, iChat still refuses  
to cooperate: "The application iChat quit unexpectedly. The problem  
may have been caused by the IOXperts Webcam plug-in". That's what the  
error message actually said.

I turned the bandwidth back up to full and was still able to have both  
cams running on HackTV and QuickTime Player. It's just that some apps,  
especially iChat and Skype, don't like this dual USB cam thing.

OK, although I doubt you'll find a UVC camera cheaper than the XBox  
one. I don't even have an XBox; I bought it for my Mac. The QuickCam  
produces superior images though.
