Since you mention QExtSeralPort, i assume that you intend to work with serial ports and nit really USB. The serial port may be a virtual port provided over USB.
Qt itlself does not provide any means to deal with serial or USB hardware. You will need to depend on other libraries such as QExtSeralPort for serial ports and perhaps libusb for USB.
