I have a usb-to-serial PL2303, I hope serial port class auto detect it and add or delete it at combobox when I insert or pull out. What I want to know is how to AUTO set the signal to my slot when this usb device insert or pull out.
@VRonin THANK YOU!
QSerialPort is an I/O device, it has nothing to do with your OS detecting new hardware. you can use libusb to detect plug events. see an example here
