I've seen some discussion about this in January 2010 on this list. Has
this issue been resolved? For those who don't remember or haven't seen
the post, it is here:

Essentially the camera seems to request the highest bandwidth regardless
of fps, resolution, compression (raw or mjpeg).
Has anybody come up with a solution for this? Is there a patch, or one
in progress? Anyway of ignoring the camera request, or forcing it to
accept less bandwidth as necessary?
I have tried vlc, ffmpeg, motion - it will not allow me to use more then
one MS Lifecam Cinema at the same time because of usb bandwidth
limitations - even if I force mjpeg compression, low fps (down to 1) and
low resolution (320x240). On the other hand, I have a Logitech QuickCam
Pro 9000 (with similarly high spec) and two MS Lifecam VX-5000 - and I
can use all three at the same time if I force mjpeg compression, with
640x480 and fps 10 - so it would be possible.
