/* Vendor-specific command structure
*
* This structure is used to pass vendor-specific commands to the mouse

* data follows the structure in a contiguous block of memory.
*
* The vendor-specific command is defined by the vendor and is not
* standardized. The data format and meaning is defined by the vendor.
*
* The usage is as follows :
*
* struct mse_vendor_data_s
* {
* uint16_t cmd;
* uint16_t len;
* uint16_t data;
* ... ... ...
* };
