### BiBoard V1 USB Driver to access the serial port

{% hint style="warning" %}
Some USB cables are just for charging and do not have data transfer capability. Using the original data cable in the kit is better for making the uploading successful. &#x20;
{% endhint %}

When you use a USB type-C data cable to upload the firmware for the **mainboard.**

* In Windows, if there is **no** serial port in the port list of **Device Manager**:

* In Mac, open the **Terminal** program under the **Applications**-**Utilities** folder and type the following commands. If no serial device name starting with "***tty.wchusbserial***" or "***cu.wchusbserial***" is found:

  <pre><code>cd /dev
  <strong>ls
  </strong></code></pre>

#### Please download and install the USB driver:

* Windows: <https://www.wch-ic.com/downloads/CH343SER_EXE.html>

2. &#x20;Install it on the Chromebook. Please refer to the video at <https://www.youtube.com/watch?v=2cve6n4LZqI>
3. &#x20;Plug the Bittle USB type-C data cable into the robot and the Chromebook.
4. Set the Chromebook Linux VM to recognize the USB port

&#x20;      Settings => Advanced => Developers => Linux development environment => Manage USB devices => USB Serial (turn on)

NOTE: Step 4 must be repeated whenever the USB connection is reconnected/powered on.
