USB Programming with Qt

Question

Is there anyway I can do USB programming in Qt? I am using Qt Creator 2.6 which is based on Qt version 5.0.0 and it is the latest Qt Creator which works with the Microsoft V

Answer 1

ollo's answer is out of date. TL;DR is use libusb.info. A bit of explanation:

Originally there was libusb-0.1. Later they updated the API to libusb-1.0, but since libusb-0.1 had been around so long many projects didn't bother switching (kind of like Python 2/3). libusb-0.1 was not available for Windows, but libusb-1.0 is now available for all major platforms.

libusb-win32 is a port of libusb-0.1 to Windows. You shouldn't use it for new code.

libusb.org is the old website for libusb. The latest release is from 2012 and there are no Windows downloads.

libusb.info is the current website for libusb. It contains libusb-1.0 downloads for all platforms and you should use this for new code.

To further confuse things, the sourceforge libusb-win32 mailing list is still used for libusb.info's development.

Answer 2

There's another good instruction for libusb here: http://www.dreamincode.net/forums/topic/148707-introduction-to-using-libusb-10/

• libusb:
  • libusb
  • libusb-win32 (windows port - use this on windows!)

If you stay on windows you can use

• WinUSB:
  • WinUSB API
  • Example
  • Installation

For windows you can use both, but if your program has to be cross-platform you should use libusb.
