VoCore Forum

I have built a new firmware of my project, when update it in the board. the usb port can't work. once I insert a usb Cam to the board.
the kernel message show below:
[ 56.350000] usb 1-1: device descriptor read/64, error -145
[ 72.080000] usb 1-1: device descriptor read/64, error -145

[ 93.490000] usb 1-1: device not accepting address 5, error -145

connected timeout. did I miss some driver of USB?
who can help me?

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?

my kernel version is 3.14.30

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)

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