The EEPROM is available for reading and writing under Linux at the pseudo file /sys/bus/i2c/devices/0-0050/eeprom. The content of the eeprom is the following:

Normally, after applying power, you have to push the button to turn on the ns2. If you want it to switch on automatically, you have to switch a bit in the i2c eeprom. The bit is at offset 14 in the eeprom, changing it from 0 to 1 will enable auto switch on.
