# motospeedv40-re: decoding Motospeed V40 mouse HID commands

> motospeedv40-re documents USB HID commands used by the Motospeed V40 mouse. The author captured Windows-driver traffic with Wireshark and records report sizes, initialization and settings commands, DPI byte values, and packet captures with diffs.
