How many data transmission modes are there in a USB Connector?

[jamesgarcia0619]

Although I often use a USB Connector, I have no idea how it works. It would be great if anybody can explain it to me.

Do you mean the physical connector, or the communication standard?

I mean there is plenty info on it online:

• https://en.wikipedia.org/wiki/USB - for broad overview
• https://en.wikipedia.org/wiki/USB_(Physical) - connectors, cables, power
• https://en.wikipedia.org/wiki/USB_(Communications) - signals, protocol

Actual spec: http://www.usb.org/developers/docs/
Download the zip it seems to have everything.
