Troubleshoot "Device not found"

[For D1/D1 Pro] Problem: "Can't find device connected through USB"

Video of the Troubleshooting Process:

Possible Cause(s) & Solution(s): 

It could be that the driver required for the machine was missing or was not successfully installed. Normally, if that's the case, a notice will pop up reminding you to install it. Do as instructed, click on "Install" till it finishes successfully, then replug the USB cable and try again.

In case the notice does not show up, follow the steps below to install the driver for your Windows computer or Mac.

Driver Installation Steps for Windows:

1. Ensure that you have used a USB cable to connect your device to the computer and turned on the device. (Ensure that the USB interface of the computer works properly).

2. Download the CH341 driver here and finish the installation. (You may need to restart the computer during the process. Follow the instructions.)

3. Open Device Manager and check whether the CH341 driver is installed.

On Windows, when a hardware device is inserted into the computer, the system automatically identifies the device and includes it in the device manager. We can view the serial port in the device manager by performing the following steps:

(1) Right-click My Computer (or Computer) and choose Manage.

(2) Choose Device Manager in the window that appears. Click Port. Check if the serial port of USB-SERIAL is CH340

The information COM3 included in the parentheses is the serial port.

If you can see the CH340 driver on Device Manager, D1 Pro is supported to identity the serial port properly.

If you can see the driver but D1 Pro still fails to identify the serial port, the identification program of D1 Pro may be blocked by the security software. Close such software as firewall or computer housekeeper, and reinstall again.

Driver Installation Steps for macOS:

1. Ensure that you have used a USB cable to connect your device to the computer and turned on the device. (Ensure that the USB interface of the computer works properly).

2. Download the CH341 driver here and finish the installation.

(You may need to restart the computer during the process. Follow the instructions.)

3. Allow the CH341 driver after the restart.

The system instructs you to restart the computer once again after you click to allow the installation of CH341.

Restart the computer. After the preceding operation, D1 Pro is supported to identify the serial port of your device.

If no "Allow" option is provided in step 3, go to step 4.

4. For macOS High Sierra 10.13 or later, kernel extensions can be installed only when users agree. D1 Pro uses the CH341 serial port driver. You can connect D1 Pro only after you agree to install the CH341 serial port driver.

Solution

(1) Start the command-line terminal: Choose Go > Utilities > Terminal.

(2) Copy the following command: sudo kextload /Library/Extensions/usbserial.kext/

(3) Paste the command on the terminal and press Enter.

If the Password command appears, enter your computer user password and then press Enter. The following information is displayed:

(4) Choose System Preferences > Security & Privacy > General. You can see that the program is blocked. Click Allow.
