USB HID connect on QT?

please help me. i fighting with read generic data USB HID in a QT project on Linux or window.this project will receives company' name and read files in USB and after they will be send to interface of QT. i still do not know.thanks for help me!!

Show code and explain exactly which part doesn't work and what it should do.

Sorry but isn't HID used for devices such as mice and keyboards and not transferring files? Isn't mass storage what you want? If you're using a standard device then Windows will mount it by itself and you can access it as any other disk in your system.

thanks for reply,..I have not done it .. it's just an idea,if you have an example as this, please give me..thank you very much!!

We have no idea what you are trying to do so it is not possible to give you any examples.

Hi i am just starting on QT,

My aim is to make a QT application that reads data through USB port (HID) sent from a Micro-Controller,

Would you have any example to recommend ?

Qt has no facilities for direct USB access. If your microcontroller presents like:

• a keyboard or mouse, then you will receive the data through either mouse or keyboard events after it has been processed by the operating system;
• a game controller, UPS or other HID device, then you will likely not see events in Qt; or
• a virtual serial port (i.e. not HID) then you can use one of several Qt-based serial port classes to access the port.

If you need low-level direct USB access then you should look at using the third-party libusb or you could use your platform's USB API directly.

You can use HID API library: http://www.signal11.us/oss/hidapi/

Thanks so much Chris and Pavlya,

I found a QT example integrating the libusb but
i could not compile it well with my limited knowlege https://github.com/iia/Qt_libusb

I am a bit lost on how to use libusb on QT, any ideas ?
