  • Libusb is a free and open-source library that permits client space applications to get to USB gadgets without the requirement for bit-mode drivers. It is accessible on different working frameworks, including Windows, macOS, and Linux. The ease of use of libusb is one of its primary benefits. It gives a basic and reliable connection point for getting to USB gadgets, which can be useful for engineers who need to work with USB gadgets in their applications. Additionally, a wide variety of USB devices are supported by libusb, including those with proprietary protocols or interfaces. Additionally, Libusb is very customizable. It makes it possible for programmers to develop individual drivers and applications that can interact in novel ways with USB devices. In addition, there is a large and active developer community for libusb, which is always working to improve the library and add new features. The portability of libusb is yet another advantage. The library can be utilized on various working frameworks, which can be useful for designers who need to make cross-stage applications that interface with USB gadgets. However, it's important to remember that libusb may have some limitations and problems. For instance, it may not work with some USB gadgets that require bit-mode drivers or particular equipment. Additionally, the library's documentation and resources may be less comprehensive or user-friendly than those of other libraries for some users. Generally, libusb is a profoundly valuable and adjustable library that gives a steady and simple to-utilize interface for getting to USB gadgets. Its convenience and support for custom drivers and applications make it an extraordinary apparatus for designers who need to work with USB gadgets in their applications. Users should, however, be aware of the library's potential drawbacks and be prepared to spend some time learning how to use it effectively.
  • Insane
  • it's awesome!
  • Great lib to interact with usb ports in unix-like operating systems
  • I was able to use this to write Visual C++ 2008 code on Windows 7 that talks to a FadeCandy to control my Christmas tree lights. It was easy to download and write working code, thanks! Suggestions include: 1) libusb.h has three structs with arrays with 0 elements. This causes compiler warnings as VC++ 2008 doesn't define __STDC_VERSION__. Is there a reason these cannot be defined as having one element? 2) since most functions return a return code into an int, it requires a cast to call libusb_strerror() without a warning or error. Is it not possible to simply have this function accept an int arg? 3) the documention is copious but I would have benefitted from an overview of USB, such as what "configurations" and "endpoints" are. 4) initial projects also seem to go much faster with good hello-world examples. listdevs.c was great for finding the device I needed, but it took a while to figure out that libusb_claim_interface() wasn't needed. I found some step-by-step instructions on how to call _open and _free_device_list, for instance, that didn't go on to state that I then had to claim an interface before using it.
