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!
