4-Zone Mouse Senso

Integration Guide

7.0 USB Information

Communication to the microprocessor is done via USB and:

 Uses the low speed USB standard

 Is compatible with any USB 1.1 or 2.0 host

 Enumerates as HID device

The microprocessor reports data to the host at a rate of 50 reports/sec.

7.1 Device PID and VID

 This IC’s Product ID (PID): 0x0002

 Interlink’s Vendor ID (VID): 0x214A

7.2 Data Packet

The data packet from the chip is organized as:

 Byte 0

o Bit 0 is the Left Button status

o Bit 1 is the Right Button status

o Bit 2 is the Middle button status

 Byte 1 reports the X direction. The values range from -127 to +127 counts.

 Byte 2 reports the Y direction. The values range from -127 to +127 counts.

7.3 USB Suspend Mode

The chip will not respond to a “suspend” command from the host. It will always stay active

with the current consumption as described in section 8.3.

Note: This device will not wake the host from suspend mode.
