I'm not sure that's a problem: As far as I understand, gphoto2 talks to 
the camera as a generic USB device.

It could, as you say, be usbdevfs, if gphoto2 uses that.  what does
# cat /proc/bus/usb/devices
say?

Most of the gphoto2 faq's revolve around permissions to the usb device:

http://gphoto.sourceforge.net/doc/manual/permissions-usb.html

It also seems to depend on hotplug support.  Do you have the package 
"hotplug" installed?

That means you're using usb-storage to access that, which is fine, but I 
don't think your DShot II supports usb-storage.  Gphoto2 is using a 
different mechanism to access the DShotII, so it might be a 
configuration problem with the USB.
