Yeah, I don't have the error on my mainstone, which kind of hinders my debug
capability.
I have tried your script, and this is what I get :
- dmesg | tail
random: crng init done
gadgetfs: USB Gadget filesystem, version 24 Aug 2004
configfs-gadget gadget: uvc_function_bind
[DEBUG] opts->streaming_maxpacket=256
====name: ep1in-int, mp=16
====name: ep1in-int, mp=16
====name: ep2in-int, mp=16
====name: ep3out-int, mp=16
====name: ep4in-iso, mp=256
- lsmod
Module Size Used by Not tainted
usb_f_uvc 40752 6
libcomposite 38099 14 usb_f_uvc
pxa27x_udc 21131 0
gadgetfs 16173 0
videobuf2_vmalloc 4659 1 usb_f_uvc
videobuf2_memops 1421 1 videobuf2_vmalloc
This was tried on a mainstone board, upon mainline kernel v4.8-rc3 with your
patch. but without an actual camera nor the USB cable attached to a host USB.
Cheers.
