Hi-

I have a ubuntu 11.04 machine that I'm trying to capture 12 usb webcam feeds 
on.  The webcams are split over 3 pcie usb cards and the motherboards's usb 
controller.  I'm encountering instability using both streamer and guvcview.  I 
can get all 12 streams running but eventually one dies (in a minute or so) and 
then about 3 more die as well...leaving me with 7 or 8 stable streams.  What is 
the limitation?  The guvcview error is:

Could not grab image (select timeout): Resource temporarily unavailable


which is repeated repeatedly....


the streamer error is:
v4l2: oops: select timeouts

this usually only effects one or two cameras



with both programs dmesg yields:

[ 5330.048166] uvcvideo: Failed to resubmit video URB (-27).
[ 5330.048174] uvcvideo: Failed to resubmit video URB (-27).
[ 5330.048178] uvcvideo: Failed to resubmit video URB (-27).
[ 5330.048183] uvcvideo: Failed to resubmit video URB (-27).
[ 5330.048188] uvcvideo: Failed to resubmit video URB (-27).


I only need to capture an image from every camera every 2.4 seconds, if someone 
can provide me a good work-around I'd appreciate it!

-cheers
jason
