+//		Default processing of I2C and EEPROM packets. Inherited EP1 packet handlers normally
+//		don't override I2C and EEPROM packet processing. They implement (most of the time) new 
+//		features, which have simple data transfer only. EP1 is not intented to use for transfering 
+//		large amount of data, e.g.: jtag, or LA stream.
