The interface can not be claimed because the kernel doesn't think
that it exists. The error is actually really clear.
When I plug in the stick correspondent devices
are created under
/dev/usb/
USB is a packet bus with highly structured communication. Device
nodes in /dev are not a good reference.

Unfortunately the fritzbox has a useless mini lsusb program as
opposed to the actual lsusb utility from the usbutils package.
It would be great if you could build the real one.
Somewhat less effort and still interesting would be to mount debugfs
and then cat /sys/kernel/debug/usb/devices
Other than that, it would be helpful if you could build a libusb
binary with debug logging enabled. See
http://libusb.org/wiki/debug
for copypaste instructions that would apply to a host build. You must
modify them as appropriate for your cross build of course.
For debugging is not enabled by default in this kernel and building
a new one and/or complete lsusb, I looked for another way to get
the needed information. I noticed that the debugging package "listusb"
is available for the box and I build it. Here the output of listusb -v:

Can you see there what is going wrong?
