Re: USB error
I get this error when I develop VoCore. I confused D+, D-. Maybe you are some issue.

Hi vonger:
I don't think it's result in D+,D-. cause I have read the blog "MJPG Camera" , and try the full image from the link, the board works wondfully!
and I have checked the drivers you listed in it. all of them are included. So where is the difference between your image and what I have built?

Re: USB error
Hi vonger:
I found the usb drivers were not insmod successfully?
when I insmod the usb driver manually, kernel shows
kmod: failed to insert usbcore.ko
usbcore: exports duplicate symbol __usb_get_extra_descriptor ( owned by kernel)

Re: USB error
usbcore driver already in VoCore.
That should be other usb driver issue.
Make sure every dependency driver you have installed.
