Introduction

Pyusb is a Python package that allows communication with USB devices. However, some Windows users encounter an issue called No Backend Available when trying to use Pyusb. In this article, we will explore some methods for solving this problem. We will compare the different solutions and discuss their advantages and disadvantages.

The Problem: No Backend Available

When using Pyusb on Windows, some users may encounter an error message that says No Backend Available. This error occurs because Pyusb relies on a backend library to communicate with USB devices. However, some Windows systems do not have the necessary backend library installed.

Solution 1: Install libusb-win32

One solution to the No Backend Available problem is to install the libusb-win32 backend library. This library provides a Windows driver that allows communication with USB devices. To install libusb-win32, you can follow these steps:

  1. Download the latest version of libusb-win32 from the official website.
  2. Extract the downloaded file to a directory in your computer.
  3. Run the file inf-wizard.exe located in the extracted directory.
  4. Follow the installation wizard instructions to install the driver.

This method is effective but it requires some technical knowledge to carry out the installation process. Moreover, some users may find it difficult to troubleshoot if any problems occur during installation.

Solution 2: Use Zadig Tool

Zadig is a tool that allows installation of generic USB drivers on Windows. By using this tool, you can replace the default Windows driver with a generic driver that works with Pyusb. To use Zadig, follow these steps:

  1. Download and install the Zadig tool from the official website.
  2. Connect your USB device to the computer.
  3. Run the Zadig tool and select your USB device from the list of devices.
  4. Select libusb-win32 from the target driver list and click Install Driver.

This solution is relatively easier than the first solution. However, some users may find it challenging to locate the right target driver in the Zadig tool. Also, it doesn’t work for every device model, so this method is not suitable for all cases.

Solution 3: Use pywinusb Backend

Pywinusb is another backend library that can communicate with USB devices on Windows. To use pywinusb, you need to install it using pip. Then, you can modify your Pyusb code to use pywinusb as the backend. Here are the steps:

  1. Install pywinusb using pip: pip install pywinusb
  2. Modify your Pyusb code to use pywinusb as the backend.

This method is the easiest to implement as it only requires a code modification. However, it may not be suitable for everyone as some users may not want to modify their existing Pyusb code, or they may not have any experience doing so.

Comparison and Opinion

In this section, we will compare the different solutions discussed above and provide our opinion on which solution is the best.

Solution Advantages Disadvantages
Install libusb-win32 Effective and reliable Requires technical knowledge; difficult to troubleshoot
Use Zadig Tool Relatively easy; works for some devices May be challenging to locate the target driver; doesn’t work for all devices
Use pywinusb Backend Easy to implement; no installation required May not be suitable for everyone; requires code modification

In our opinion, the best solution depends on the user’s situation. If the user has technical knowledge and is comfortable with troubleshooting, then installing libusb-win32 is the most effective solution. On the other hand, if the user is not familiar with technical installations, then using Zadig Tool may be the best approach. Finally, if the user is comfortable with modifying code and does not want to install any libraries, then using pywinusb is the easiest method.

Conclusion

In conclusion, solving the No Backend Available problem with Pyusb on Windows can be accomplished using different methods. The choice of solution depends on the user’s experience and comfort level with technical installations and code modifications. Regardless of which solution is chosen, it is essential to understand how the backend libraries work and what they offer in terms of functionality and reliability.
