Whilst the chip in question will do your job, it is upto yourself to write the code to make it work or buy a library that does it for you. To understand the operation you need to understand the inner workings of USB which is not trivial also you'd probably need special USB equipment to simulate the USB operation. All this is big dollars and/or a lot of time.

As the others have suggested, use a FTDI chip that does all the USB magic for you and comes with windows drivers - again ,a 'no-brainer'. Or as Erik suggests buy a USB-serial adapter - I've done this a few times and remove the MAXxxxx chip for the RS232 level conversion - you can then connect the 3v serial signals to you cpu (assuming it is 3v also). I wouldn't recommend Belkin USB-serial adapters even though they have an 8051 device in them - they don't do 7bit data (this may not be a problem).
