What is the most recent version of the USB spec?
The most recent version of the spec is 2.0, and it includes one ECN which contains the spec for the “mini-B” connector. Please check the www.usb.org/developers page for the absolute latest version of the spec. top 19. Can you point me to where I can get some information regarding mini-A and mini-B receptacles? OTG is a new concept to our product lines and we need to get a lot of information to make product development decisions. A: Mini A Connectors are not permitted per the specification. The On-The-Go Supplement to the USB 2.0 Specification does not allow the use of mini-A receptacles for anything except an adapter as outlined in Section 3.8 Connectors. The mini-AB receptacle is not permitted on any device except OTG. An On-The-Go device by definition has a mini AB receptacle. Mini B connectors are not limited to On-The-Go devices and are used on On-The-Go and non On-The-Go devices.
