3. Method 3: Using ARP Command
4. Method 4: Using Network Connections and Status
5. Tips and Conclusion

Method 1: Using Ifconfig and /proc/net/route

1. Connect your USB device to your Linux computer.
2. Open your terminal application and enter the command “ifconfig -a”. This command lists all the network interfaces on your system, including your USB connection interface.
3. Look for the network interface that lists your USB connection. It should be labeled “usb0”.
4. Once you have located your USB connection interface, you can retrieve its IP address by typing the following command: “cat /proc/net/route | grep ”. Replace with the name of your USB interface.
5. Hit Enter, and you should now see a series of numbers and letter that represent the IP address of your connected USB device.

Method 2: Using Lsusb and Dmesg Commands

1. Connect your USB device to your Linux computer.
2. Open your terminal application and enter the command “lsusb”. This command lists all the USB devices attached to your system.
3. Find your USB device's ID by checking the vendor and product ID numbers.
4. Once you have found your USB device's ID, enter the command “dmesg | grep ”. Replace with the vendor and product ID of your USB device.
5. Now you should see a series of messages displayed in the terminal. Look for the message containing a sentence that indicates a successful connection to your USB device, which usually contains the IP address information.

Method 3: Using ARP Command

1. Connect your USB device to your Linux computer.
2. Open your terminal application and enter the command “ifconfig”. This command lists all the network interfaces on your system, including your USB connection interface.
3. Locate your USB connection interface, which should be labeled “usb0”.
4. Once you have located your USB connection interface, enter the command “arp -a”. This command lists all of the IP addresses connected to your network, including your USB device's IP address.
5. Scroll through the list of IP addresses and find the one assigned to your USB device.

Method 4: Using Network Connections and Status

1. Connect your USB device to your Linux computer.
2. Click Start -> Control Panel -> Network and internet connections -> Network Connections.
3. Highlight the Local Area Connection icon, right-click it, and select “Status”.
4. Go to the “Support” tab and you should see your USB device's IP address displayed in the “Details” section.

Tips and Conclusion

• It is important to always check the connectivity of your USB device by pinging its IP address.
• If none of the methods above worked for you, you may need to configure the IP address of your USB device manually. Check the user manual or contact the manufacturer for instructions.
• Knowing the IP address of your USB device is vital in setting up printers, servers, and other peripherals.
• It is always recommended to use a static IP address if you're planning to use your USB device in the same network frequently.

Finding the IP address of a USB connected device in Linux can be challenging, but following any of the methods above should provide you with the necessary information. This guide will be helpful in configuring and using your USB device effectively.
