|                   |                             |
|-------------------|-----------------------------|
| **Product name**  | `電車でGO! コントローラ USB版` |
| **Manufacturer**  | `TAITO`                     |
| **Vendor ID**     | `0x0AE4`                    |
| **Product ID**    | `0x0003`                    |
| **Serial number** | `TCPP20009`                 |

The controller sends reports to the host (PC) formed by 6 bytes:

| Byte 1 | Byte 2 | Byte 3 | Byte 4  | Byte 5 | Byte 6 |
|:------:|:------:|:------:|:-------:|:------:|:------:|
| Brake  | Power  | Null   | Buttons | Null   | Null   |

The values for the brake notch byte are the following. There are 5 unmarked positions between **B8** and **Emergency**, but unlike classic controllers, they are all report the value for **Emergency**.

| Released | B1   | B2   | B3   | B4   | B5   | B6   | B7   | B8   | Emergency | Transition |
|:--------:|:----:|:----:|:----:|:----:|:----:|:----:|:----:|:----:|:---------:|:----------:|
| 0x79     | 0x8A | 0x94 | 0x9A | 0xA2 | 0xA8 | 0xAF | 0xB2 | 0xB5 | 0xB9      | 0xFF       |

The values for the power notch byte are listed below.

| N    | B1   | B2   | B3   | B4   | B5   | Transition |
|:----:|:----:|:----:|:----:|:----:|:----:|:----------:|
| 0x81 | 0x6D | 0x54 | 0x3F | 0x21 | 0x00 | 0xFF       |

The button byte uses six bits to represent the state of the physical buttons. **0** means that the button is released and **1** that it is pressed.

| Button 1 | Button 2 | Button 3 | Button 4 | Button 5 | Button 6 |
|:--------:|:--------:|:--------:|:--------:|:--------:|:--------:|
| B        | A        | C        | D        | SELECT   | START    |
