Summary

My YOGA requires a minimum of 7 to parse w/o an error. Since the memory
savings are trivial and the yoga a popular system, bump the default
up to 8. There's no API/ABI issues in doing this. This hid_item
struct isn't exported to userland and the one libusbhid has is
different and only shares a name...

# kldload hidraw.ko
# usbhidctl -f /dev/hidraw# -r

Ouch, I forgot that usbhidctl is unable nor properly parse such a descriptor nor do a raw dump. So no easy way right now, rebuilding of kernel with debug options enabled is required. Just forget.
