Usb

Any one knows where can I learn how USB works?
Specifications for USB 1.1?
How is the data encoded and transmitted, formats, frames, etc?

Any help will be greatly appreciated, guaranteed!

Zanks!

www.usb.org :)

Thanks a lot, Parksie. I had already checked out usb.org, but could only find info on the new usb 2.0 specs, and I was interested in the more traditional 1.1 version.
But looking more deeply, I found it at http://www.usb.org/developers/data/usbspecs.zip
