Hi all,
I’m doing project about face recognition by webcam on BB-xM, My code runs on computer so well but when I compile and run it on BB-xM, it just runs for a while and then it has error:
[ 3610.829467] gspca_main: ISOC data error: [22] len=0, status=-18

…
I have searched this error, many people say it is related to webcam access and kernel but I don’t know how to solve it. My BB-xM runs Ubuntu 14.04 Trusty. I don’t have a monitor which has HDMI or DVI port, so I can’t test the webcam thoroughly but I think the webcam can work because when I try to capture images with webcam, the result is good.
Thank you for helping me.
