+//! # Yuancon Laverita v2
+//! (does anyone still use this?)
+//! 
+//! Notes: I'm getting conflicting information on the protocol.
+//! CrazyRedMachine is claiming that there is [a leading byte][1], while 4yn's 
+//! [slidershim][2] as well as their earlier [Yuancon HID test script][3] is 
+//! claiming the opposite. This implementation is based on CrazyRedMachine, 
+//! since the chuniio open-sourced by ZhouSensor himself seems to agree.
