USB Dual Framework

This feature description is new in the Solaris 9 4/04 release. This feature is available for x86 platforms and SPARC platforms.

The USBA framework, found in the Solaris 9 12/03 release, was originally developed for USB 1.1 devices. A new framework, called USBA 1.0, was created to meet the more demanding requirements of USB 2.0 devices. The framework operates USB 1.1 devices as well. This Solaris release provides both frameworks, as a dual framework. The purpose of the dual framework is to facilitate a smoother transition from the original framework to the newer framework. The original USBA framework operates devices that are connected to a system's USB 1.1 ports, while the new USBA 1.0 framework operates devices that are connected to a system's USB 2.0 ports.

All Sun motherboard ports are USB 1.1 ports, while most PCI card ports support USB 2.0.
