Appendix F: USB data reporting format
The USB report has two formats, depending on if boot or report protocol is enabled. The following format is the boot
protocol and is understood by a USB aware BIOS.
The following is the 16-bit USB report protocol format and allows the additional wheel movement information in the
fourth byte. When the wheel is moved forward the fourth byte reports a 0x01, and when moved backward the fourth
byte reports 0xFF. When the wheel is idle, then this byte is assigned 0x00.
