USB End-User Device Support Enhancements

These enhancements are new in the Solaris Express 5/04 release. New programming interfaces were added in the Solaris Express 8/04 release.

All current Edgeport USB-to-serial devices now work with this Solaris release. USB 1.1 audio and other isochronous devices now work behind USB 2.0 high-speed hubs.

New Programming Interfaces

These interfaces are new in the Solaris Express 8/04 release.

Universal Serial Bus Architecture (USBA) 2.0 programming interfaces are being released publicly as part of the Solaris 10 OS. These interfaces are documented as usb_* functions and structures in man page sections 9F and 9S. See also Writing Device Drivers.

The USBA framework now is called USBA 2.0. USB drivers that were written to USBA 1.0 interfaces in prior DDKs are only binary compatible with the Solaris 10 software. These drivers are not source compatible with the Solaris 10 software.
