Feature reports are sent over the Control endpoint as a
Set_Report transfer. The first byte of @p data[] must
contain the Report ID. For devices which only support a
single report, this must be set to 0x0. The remaining bytes
contain the report data. Since the Report ID is mandatory,
calls to hid_send_feature_report() will always contain one
more byte than the report contains. For example, if a hid
report is 16 bytes long, 17 bytes must be passed to
hid_send_feature_report(): the Report ID (or 0x0, for
devices which do not use numbered reports), followed by the
report data (16 bytes). In this example, the length passed
in would be 17.
