 
 <prompt> Wetin dey less, potential states for di data lines or consecutive 1 bits for error? Based on di previous question, write a context wey contain di answer. E fit be 1 - 20 sentences. Context: <response>: ```USB data dey waka by dey switch di data lines between di J state and di opposite K state. USB dey encode data using di NRZI line coding; a 0 bit dey waka by switching di data lines from J to K or vice versa, while a 1 bit dey waka by leaving di data lines as e be. To make sure say di signal transitions dey dense reach, USB dey use bit stuffing; an extra 0 bit dey put inside di data stream after any appearance of six consecutive 1 bits. Seven consecutive received 1 bits na always error. USB 3.0 don introduce additional data transmission encodings.```
