3) USB attach

If you need to use USB port for Serial or Modbus,

Reference to the official Microsoft documentation on WSL.

• https://learn.microsoft.com/en-us/windows/wsl/connect-usb

1. Open Command Prompt as Administrator

   

2. Enter command for checking the List all of the USB devices connected to Windows.

   CODE

   usbipd wsl list

   

3. Enter command for selecting the bus ID of the device you’d like to attach to WSL and run this command.

   CODE

   usbipd bind --busid <BUSID>
   usbipd attach --wsl --busid <busid>

   e.g.
   usbipd bind --busid 4-3
   usbipd attach --wsl --busid 4-3

   

When using a USB hub to connect devices, there might be compatibility issues with WSL2.

If you have 'usbipd: error: There is no WSL 2 distribution running; keep a command prompt to a WSL 2 distribution open to leave it running.' error.

1. Enter the below commands

2. Open new Command Prompt as Administrator

3. Retry usbipd attach command.

CODE

wsl -l -v
wsl --distribution Ubuntu-20.04-dra

4. Enter the WSL terminal (wsl --distribution Ubuntu-20.04-dra) and input the following command.

   CODE

   wsl --distribution Ubuntu-20.04-dra

   CODE

   sudo modprobe usbserial
   sudo modprobe ftdi_sio
   sudo modprobe cp210x

   

5. After verifying that ttyUSB0 has been created, adjust its permissions by entering the following command.

   CODE

   ls -l /dev/ttyUSB*
   chmod -R 777 /dev/ttyUSB0

   

If the USB port does not appear when executing the command ls -l /dev/ttyUSB*, you can try unplugging the USB device and plugging it back in, or using a different port. When switching to a different port, make sure to unbind and detach the existing device using the following steps.

• usbipd: info: Device with busid '2-6' was already shared.

CODE

usbipd unbind --busid 2-6

• usbipd: info: Device with busid '2-6' was already not attached.

CODE

usbipd detach --busid 2-6

If you have an error, please see the below.

Error 1. The selected WSL distribution is using WSL 1, but WSL 2 is required.

• Step 1. Enter the following command into the terminal to select WSL2.

wsl --set-version Ubuntu-20.04 2

Error 2. WSL ‘usbip’ client not correctly installed.

• Step 1. From Terminal on Ubuntu 20.04 (Ubuntu Terminal is available from the Windows Store: https://apps.microsoft.com/store/detail/windows-terminal/9N0DX20HK701?hl=en-us&gl=kr)

• Step 2. Enter the following commands sequentially

sudo apt-get update
sudo apt install linux-tools-virtual hwdata
sudo update-alternatives --install /usr/local/bin/usbip usbip `ls /usr/lib/linux-tools/*/usbip | tail -n1` 20

Error 3. When USB Port(e.g. ttyUSB0) is not visible on Ubuntu

This issue arises from changes in WSL and usbipd, which are beyond our control. While not a perfect solution, a user on Dart-Forum has shared that modifying the kernel settings as described in the following link can help address the issue.
