It really depends on the device you wish to communicate with.
Usually device manufacturers provide APIs to the purpose.
For instance many 'slow' devices use virtual COM over USB so that, once installed the required drivers, you communicate using standard RS232 protocol.

I can say that not all USB devices are fast:). I mean HID (Human Interface Device) USB devices. If you are planning to use "fast" USB, my advice, use FTDI chips. Practice shows that they are very convenient.
Search Codeproject articles for 'USB'.
