Caanoo / WIZ Wiz Kernel Usbdevfs Support?

[jpleveillee]

Is the usbdevfs enabled in the wiz kernel ?
I managed to get gphoto2 or multican working on my wiz but my camera
is not detected because of missing kernel config like usbdevfs

Can someone help me with setting a cross_compile environment
for compiling a new kernel with all the USB options needed?

Thanks
JP

We have had some threads about Wiz kernel building already, look here.

thanks notaz

how we can boot a new kernel uImage from the SD without flashing?

i dont think it is supported. but i dont think you need to reflash your firmware anyway? wouldn't it be just sufficient to compile usbdevfs as a module and just use the insmod command and what else it needs before executing your software?

 

[jpleveillee]

it works
I recompiled usbcore.ko and ohci_hcd.ko with usbfs support

now I can see my camera in /proc/bus/usb

but I need to set the USB permission

I think this is the last thing to do to make gphoto2 and multican working

It work !!
Multican run well with Libusb and my modified usbcore.ko kernel module ..
I can now control my Canon camera via USB for remote shooting!!

Libgphoto2 does not work because we need to set USB permission with udev but anyway I dont need it for now.

For those interested .. I want to develop a software for remote shooting DSLR with the gp2x wiz.
It will be usefull for doing HDRI photography, Timelapse or astrophotography.

Thanks for the help

so how did you do? insmod or did you create your own 'custom' firmware?

 

[jpleveillee]

I recompiled the kernel modules with USB DEVICE FILESYSTEM .
Replaced the usbcore.ko and ohci-hcd.ko in /lib/modules .. drivers/usb
added "usbfs /proc/bus/usb usbfs rw 0 0" in /etc/fstab
compiled libusb and put it in /lib

With that we can see the usb devices in /proc/bus/usb and
my application using libusb can see the usb devices

so how did you do? insmod or did you create your own 'custom' firmware?
