That means the Dongle is a Parallel port dongle that has been moved to be USB to LPT port and that the USB drivers do not support current USB3 ports and conflict at the hardware level with IRQ7.
The dongle isn't a dell product and therefore not supported by dell.
You will have to take this up with your dongle software vendor.
