  This is not really a buildroot-related question, linux-input at vger.kernel.org
would be more appropriate.

  Still, some ideas:

- I never heard of /dev/uinput or /dev/hidraw.  Input devices can usually be
found in /dev/input/.  Perhaps you need udev rules to create /dev/uinput or
/dev/hidraw?

- Look in /sys/devices/pci0000:00/0000:00:1d.1/usb2/2-2/2-2:1.0/input/input6
(and 7, 8, 9, 10); it should have an eventXX directory containing a 'dev' file.
That file contains the major:minor number of the (character) device node for
the input event device.  You should have a /dev/input/eventXX device node
with the same numbers.  That's the device you need.


  For future posts, please

- mention the buildroot and kernel versions you use;

- post a defconfig instead of a a full config;

- post text attachments with disposition:inline so people can quote them.


  Good luck!

  Regards,
  Arnout
