Could you post a couple of sample images? I getting very flaky behavior with the Beaglebone and BeagleboneBlack with and without a USB hub. I'm using HP2200 and HP3110 webcams and have tried all these kernels:
uname -a Linux beaglebone 4.1.5-ti-r10 #1 SMP PREEMPT Thu Aug 13 20:24:29 UTC 2015 armv7l GNU/Linux Linux beaglebone 4.2.0-bone2 #1 Mon Aug 31 09:45:24 UTC 2015 armv7l GNU/Linux Linux beaglebone 3.8.13-bone74 #1 SMP Wed Aug 12 00:12:46 UTC 2015 armv7l GNU/Linux Both cameras work fine on my Raspberry Pi2 using fswebcam or openCV. At this point my solution appears to be buy another Pi2 for this project. There was a bunch of updates recently, I'm applying them now and will report back if they solve the problem .
