Occasionally fswebcam -r 640x480 -S10 image.jpg would produce an Error selecting input 0 VIDIOC_S_INPUT: Device or resource busy error on my RPi 3.
I googled around a bit. I got some hits suggesting adding dwc_otg.fiq_fsm_mask=0x3 to the /boot/cmdline.txt file might fix that. It does, but it introduces new errors, 'Timed out waiting for frame!orVIDIOC_DQBUF: No such device`.
The new errors occur every time I run fswebcam so I removed dwc_otg.fiq_fsm_mask=0x3 and now I'm back to the original occasional error. But I'd like to be error free if possible.
Anyone out there understand this stuff well enough to suggest a fix?
