USB experiment board driver. Reverse engineer?

Hello all,
Another stupid question. Sorry if this should be in hardwear but I considered it more of a programming question.
Mods: Please move if appropeate.

I have started to get interested in some electronics recently and have been resurching and begining to play with the parellel port using outb and trying to work out what hardwear I need for inb. Then I saw this advertised in a flyer.

Seems pritty cool I thought I could start doing what I wanted with out having to make my own control board. Only thing is it of course only comes with a windows .dll.

My question. How hard would it be to reverse enginner a driver for this. Would it just be a case of using outb and changing the base address to that of a usb port rather than the parellel port? Could I esaly work things out from windows? This low level port hexidecimal stuff is new to me, from what I have read usb port seems a lot more work and requires a lot of understanding to deal with than the parellel port. May be it is not worth it?


Edit ULR will not link!?! Product Code is L92BL I don't know why when I copy and paste it will not link to the page.

is your link is broken? it is taking me to a page for usb hard drives.

anyhow, the first thing to do would probably be look at some existing usb driver code that is in the kernel or available elsewhere.. for the kernel its in drivers/usb ..
