Hi all,
My OS: Win32 (win xp)
I want to create a project for transfer files between two PCs by USB cable, so Can I do that by using Qt?
I did some researches about this matter,and I found QextSerialPort, but I'm not sure if it suitable for my project :confused:!
can you help me, please:crying:?
This is not possible unless you have a special cable (commonly called "USB link adapter"), which has USB devices in the middle. Although USB standard allows the same device to be both host controller and device at the same time, a USB controller on your PC does not support this feature. And if you have such cable, you do not need any project to transfer the files, since everything (including drivers) is on the provided CD.Quote:

And yet another problem is that USB programming itself is not simple if you go deep enough. There are devices, device classes, descriptors, control descriptor, states, different types of transfers, etc. In short, this is not an easy task.
