Few questions about dibusb i2c over usb protocol

[Raimonds Cicans]

Hello.

1) As I understand format of i2c read command is following:
2, (dev_i2c_addr<<1)|1, addr_hi, addr_lo, size_hi, size_lo

but in debug output I saw following commands:
 >>> 02 a3 00 01
<<< 55

 >>> 02 a3 00 04
<<< 55 00 53 00

This commands are shorter then command described above.
Meaning of bytes 1, 2 and 4 is clear, but what mean third byte:
if it is size_hi, then where is address?
if it is addr_lo, then it is not clear why answer's first byte is 55
according to Cypress documentation first byte of
program eeprom should be C2

2) What is format for i2c write command?
3, dev_i2c_addr<<1, addr_hi, addr_lo, data...   ?

3) what mean following command
 >>> 03 a2 51 3f 80

write byte 80 at address 513f?
