+ALPS HID Touchpad Protocol
+----------------------
+
+Introduction
+------------
+Currently ALPS HID driver supports U1 Touchpad device.
+
+U1 devuce basic information.
+Vender ID	0x044E
+Product ID	0x120B
+Version ID	0x0121
+
+
+HID Descriptor
+------------
+Byte	Field			Value	Notes
+0	wHIDDescLength		001E	Length of HID Descriptor : 30 bytes
+2	bcdVersion		0100	Compliant with Version 1.00
+4	wReportDescLength	00B2	Report Descriptor is 178 Bytes (0x00B2)
+6	wReportDescRegister	0002	Identifier to read Report Descriptor
+8	wInputRegister		0003	Identifier to read Input Report
+10	wMaxInputLength		0053	Input Report is 80 Bytes + 2
+12	wOutputRegister		0000	Identifier to read Output Report
+14	wMaxOutputLength	0000	No Output Reports
+16	wCommandRegister	0005	Identifier for Command Register
+18	wDataRegister		0006	Identifier for Data Register
+20	wVendorID		044E	Vendor ID 0x044E
+22	wProductID		120B	Product ID 0x120B
+24	wVersionID		0121	Version 01.21
+26	RESERVED		0000	RESERVED
+
+
+Report ID
+------------
+ReportID-1	(Input Reports)	(HIDUsage-Mouse) for TP&SP
+ReportID-2	(Input Reports)	(HIDUsage-keyboard) for TP
+ReportID-3	(Input Reports)	(Vendor Usage: Max 10 finger data) for TP
+ReportID-4	(Input Reports)	(Vendor Usage: ON bit data) for GP
+ReportID-5	(Feature Reports)	Feature Reports
+ReportID-6	(Input Reports)	(Vendor Usage: StickPointer data) for SP
+ReportID-7	(Feature Reports)	Flash update (Bootloader)
+
+
+Data pattern
+------------
+Case1	ReportID_1	TP/SP	Relative/Relative
+Case2	ReportID_3	TP	Absolute
+	ReportID_6	SP	Absolute
+
+
+Command Read/Write
+------------------
+To read/write to RAM, need to send a commands to the device.
+The command format is as below.
+
+DataByte(SET_REPORT)
+Byte1	Command Byte
+Byte2	Address - Byte 0 (LSB)
+Byte3	Address - Byte 1
+Byte4	Address - Byte 2
+Byte5	Address - Byte 3 (MSB)
+Byte6	Value Byte
+Byte7	Checksum
+
+Command Byte is read=0xD1/write=0xD2 .
+Address is read/write RAM address.
+Value Byte is writing data when you send the write commands.
+When you read RAM, there is no meaning.
+
+DataByte(GET_REPORT)
+Byte1	Response Byte
+Byte2	Address - Byte 0 (LSB)
+Byte3	Address - Byte 1
+Byte4	Address - Byte 2
+Byte5	Address - Byte 3 (MSB)
+Byte6	Value Byte
+Byte7	Checksum
+
+Read value is stored in Value Byte.
+
+
+Packet Format
