| Steps | Possible cause | Resolution |
| 1 | The most frequent cause of this problem relates to the order of the cables and the device startup sequence | Check that the cables have been connected in the correct order and that each cable is correctly plugged into the related connector. If this does not fix the problem, move on to the next step. |
| 2 | The problem occurs when devices have been started with all of the cables connected between them. | Check that the telephone and glasses were started separately. Then connect the cables on the glasses and dedicated device side. If this does not fix the problem, move on to the next step. |
| 3 | This problem occurs when one of the cables has a defect. | If you have any other OTG cables or USB-to-micro USB cables, test them separately. If this does not fix the problem, move on to the next step. |
