Techniques for stably and rapidly communicating between a mobile communication device and a personal computer are disclosed. According to one aspect of the techniques, a virtual serial apparatus is provided between a baseband controller of a mobile communication device (MCD) and a transmission driver of a personal computer (PC). The virtual serial apparatus comprises a storage unit for buffering data to be transmitted, a baseband interface unit, a physical interface unit and a USB device controller. The baseband interface unit is provided between the baseband controller and the storage unit. The baseband controller accesses the storage unit via the baseband interface unit. The physical interface unit communicates with the transmission driver via a USB bus therebetween. The USB device controller is provided between the storage unit and the physical interface unit for processing and forwarding the data to be transmitted according to a USB protocol.
