`raw_hid_receive` can receive variable size packets from host with maximum length `RAW_EPSIZE`. `raw_hid_send` on the other hand can send packets to host of exactly `RAW_EPSIZE` length, therefore it should be used with data of length `RAW_EPSIZE`.
These two functions send and receive packets of length `RAW_EPSIZE` bytes to and from the host (32 on LUFA/ChibiOS/V-USB, 64 on ATSAM).
Make sure to flash raw enabled firmware before proceeding with working on the host side.
