Qt applications and USB

[pocketchange]

I'm relatively new to Qt and I've been hoping to write an application that is cross-platform, but uses USB to communicate to a device. I'm curious how this might work in Qt. Does Qt have a means of talking to USB (hearing plug/unplug events, communicatoin, etc.) or do I need to solve that problem for each platform?

Qt itself does not support USB, so you will have to solve that problem on each platform.

However, if the USB communication is something like a virtual serial port which you have drivers for, then Qt can told to your USB device using a serial port class (such as Qextserialport, QSerialPort, etc). This is quite common so hopefully it does.

What kind of USB device? USB/Serial converter or what?
If the USB / Serial - using the fact that advised above or QSerialDevice (http://qt-apps.org/content/show.php?content=112039).
If another type of USB device - the would probably "libusb".
