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.
