how to write usb driver

[clement2011]

Hi:
I hope to develop a usb driver, like bus hound, can provide the function of
usb sniffer and have a simple transfer function to send data via interrupt,
however, i am newbie to this subject, how to start that, and is there any
good book which can help to make this. thanks a lot.

Take a look at USB Sniffer. It's open source. I have a link here:
