In this article, we will explore how to troubleshoot and fix USB 3.0 hub issues on Ubuntu 18.04. This can be a common issue for many users, but with the right steps, it can be resolved. We’ll look at several potential causes and solutions, from outdated firmware and BIOS settings to power issues.
To fix USB 3.0 hub issues on Ubuntu 18.04, you can try updating the firmware, managing the secure mode in BIOS, using a powered hub, or adjusting USB settings in BIOS. However, please note that every system is unique, and the solution may vary depending on your specific situation.
Understanding the Problem
USB 3.0 hubs are known for their high-speed data transfer capabilities. However, they can sometimes present challenges when used with Ubuntu 18.04. This could be due to various reasons like outdated firmware, secure mode in BIOS, power issues, or incorrect USB settings in BIOS.
Checking the Firmware
Outdated firmware can often be a root cause of USB 3.0 hub issues. The drivers for your USB hub might not be up-to-date with the current Ubuntu firmware.
To check if the USB driver is loaded, you can run the following command:
sudo lshw | more
Alternatively, you can use the
modprobe -l utility. If the USB driver is not listed, it means that the firmware is not recognizing it and has blocked it.
To fix this, you may need to update your bootstrap and manage your uEFI bootstrap better with SHIM/MKO. You can refer to this site for help in fixing the bootstrap.
Secure Mode in BIOS
If you have disabled secure mode in your BIOS, the new firmware might have locked out your hub. This can happen after a distro update or running
To resolve this, you may need to manage your USB utilities better. Tools for managing USB utilities can be found in Rod Smith’s book.
Sometimes, the problem could be due to power issues with the USB hub. If the hub is not getting adequate power, it might not function properly.
To solve this, try using a powered hub instead. This might resolve the problem.
USB Settings in BIOS
Lastly, the issue could be due to USB settings in BIOS. Even if your BIOS configuration does not have buttons to change USB settings, there might be other USB-related settings that could be affecting the functionality of your USB hub.
Try exploring the USB settings in your BIOS to see if it makes any difference.
In conclusion, fixing USB 3.0 hub issues on Ubuntu 18.04 involves diagnosing the problem and applying the right solution. This could range from updating your firmware, managing your boot-strap, using a powered hub, or tweaking USB settings in BIOS.
Remember, every system is unique, and what works for one might not work for another. Therefore, it’s important to understand your system well and apply the solution that best fits your situation. Good luck!
To check if the USB driver is loaded, you can run the command
sudo lshw | more in the terminal.
Updating firmware on Ubuntu 18.04 can be done through the Software & Updates application. Open the application, go to the "Additional Drivers" tab, and check for any available updates for your USB hub firmware.
Enabling secure mode in BIOS varies depending on the motherboard manufacturer. Generally, you can access the BIOS settings by pressing a specific key (like F2 or Del) during system startup. Once in the BIOS, navigate to the security settings and enable secure mode.
If your USB hub is not getting enough power, try using a powered hub instead. A powered hub has its own power source and can provide sufficient power to connected devices.
To access the USB settings in BIOS, restart your computer and enter the BIOS setup by pressing a specific key (like F2 or Del) during startup. Once in the BIOS, navigate to the "Advanced" or "Peripheral" settings, and look for options related to USB configuration or USB ports.
