Windows driver (USB to Audio/Serial)

The objective of this project is the development of a Windows driver that has USB, Audio and Serial communication. The driver has to work with XP, Vista, W7, in both 32 and 64 bit versions. The device driver has to comply with the following: WinUSB for the USB communications. It has to check for a specific USB external device if it is plugged-in. Opens the USB IN bulk endpoint and the OUT bulk endpoint that the external device has in its configuration Creates two new stereo audio output virtual ports in Windows named AudioOut1 and AudioOut2 Creates two new stereo audio input virtual ports in Windows named AudioIn1 and AudioIn2 Creates a COM: serial virtual port in Windows named as the next COM:nn available number The USB communication with the external USB attached device will be via nnn-byte blocks The nnn-byte block contents (communication protocol) are already defined in a document to be provided Data from the COM: port and audio data samples of the Audio Output ports (AudioOut1, AudioOut2) will be stored on specific places on the nnn-byte block according to the protocol definition This nnn-Byte block with formated data will be send over the USB OUT bulk endpoint to the external device The external device will then send back a properly formated nnn-byte block according to protocol definition as a reply. That reply will be on the USB IN bulk endpoint The driver will get the nnn-byte block reply and feed according to the protocol definition the COM: port and with audio data samples the Audio In ports (AudioIn1, AudioIn2) The USB Send_Block / Receive_Block sequence has to occur at a configurable nnn-usec period That periodic event will be handled by a thread and a timer that has usec resolution Examples from MS DDK/WDK can be possibly re-used and modified for the composition of this driver. To a large extend, this is an easy task since all of the comprising modules do exist in WDK/DDK, what is needed is the actual integration of them into a unified driver and the implementation of data traffic between the USB and Audio/Serial virtual ports according to the defined protocol. The data inerchange on the USB is also already completely specified (in a provided document) as a protocol of nnn-byte block. This project is not involved in development of the software that resides in the external USB device, this project is only for the driver that resides in the host windows system. Deliverables are the full project well commented source code provided in the form of a completely working MS Visual Studio Solution with any specific instructions for compile/install/run.
