What microprocessor are you using?
If it does not have a USB interface, look at FTDI.

What about usblib. it's available for windows and linux. (mas osx does not need a driver).

I think you can read the USB specification first and understand the USB concept. And then you can download the sample code of your USB device, such as from Cypress company.

hello boss,

First u go through ur embedded unit.
U go through communication modules (units) of that particular embedded unit. communication module in the sense, module which receives and transmits data. After that u will come to know all registers in that unit. Initials all registers as per ur requirement and write functions which will read and write to specific registers of the unit in order to receive and transmit data. thats it ur driver is finished.

regards,
kishore.
