Requested binding is minor, timeout 1/18/2008. -Artem Template Version: @(#)sac_nextcase 1.64 07/13/07 SMI This information is Copyright 2008 Sun Microsystems 1. Introduction 1.1. Project/Component Working Name: Integrate OpenUSB into Solaris 1.2. Name of Document Author/Supplier: Author: Raymond Chen 1.3 Date of This Document: 11 January, 2008 4. Technical Description 4.1 Summary This project integrates OpenUSB into Solaris and makes interfaces from "PSARC/2003/721 libusb: user level usb library" Obsolete. Requested binding: minor. 4.2 Details Solaris currently ships with an implementation of libusb 0.1.8 API, supporting both native Solaris USB and Sun Ray USB frameworks. Unfortunately, libusb development stagnated around version 0.1.12, bound by lack of involvement from the original author and disagreements about future directions. To revitalize development, the community created a fork of libusb, called OpenUSB, and Sun has been actively contributing to the effort. OpenUSB is licensed under LGPL and BSD licenses. OpenUSB provides a set of enhanced APIs for accessing USB devices, providing better abstraction of the diverse USB frameworks available on various platforms and ease development of portable applications. OpenUSB has the following enhancements over libusb 0.1.x: - Redesigned enumeration. New APIs for searching and managing of busses and devices, and notify application of hotplug and power management events. - OpenUSB supports multi-threaded applications (unlike libusb). - Addition of asynchronous interfaces. More flexibility over libusb 0.1.x, all of which interfaces are strictly synchronous. - Support all 4 transfer types: control, bulk, interrupt and isochronous. libusb 0.1.x did not support isochronous or control on any endpoint other than default. - Error code unification. All functions return the same set of error codes across all platforms. OpenUSB includes a libusb emulation layer, implemented via native OpenUSB interfaces, and is ABI-compatible with libusb. Legacy applications will continue to work without recompilation. OpenUSB consists of two parts: a frontend, common to all platforms, and a number of platform-specific backends. This project delivers the backend for native Solaris USB framework. The backend for Sun Ray USB will be added in the near future. This case proposes to mark Obsolete all libusb interfaces from PSARC/2003/721. This case does not remove libusb from Solaris: it will continue to coexist with OpenUSB for some time, at least until the new Sun Ray backend is delivered. OpenUSB applications will include and link with -lopenusb. Planned deliverables: /usr/lib/libopenusb.so.0.0.0 /usr/lib/libopenusb.so -> libopenusb.so.0.0.0 /usr/lib/libopenusb.so.0 -> libopenusb.so.0.0.0 /usr/lib/openusb_backend/sunos.so /usr/include/openusb.h /usr/share/man/man3lib/libopenusb.3lib /usr/share/doc/openusb/openusb_guide.html openusb.h and openusb_guide.html are in this case's directory. 4.3 Interfaces All interfaces in OpenUSB, including structures, macros and functions are Volatile. Additionally, two environment variables are exported. -------------------------+----------+----------------------------- openusb.h (see case dir) | Volatile | OpenUSB C API OPENUSB_BACKEND_PATH | Volatile | Alternative backend location OPENUSB_DEBUG | Volatile | Enable debug mode -------------------------+----------+----------------------------- 4.4.

Introduction >>> 1.1. Project/Component Working Name: >>> Integrate OpenUSB into Solaris >>> 1.2. Name of Document Author/Supplier: >>> Author: Raymond Chen >>> 1.3 Date of This Document: >>> 11 January, 2008 >>> 4. Technical Description >>> >>> 4.1 Summary >>> >>> This project integrates OpenUSB into Solaris and makes interfaces >>> from "PSARC/2003/721 libusb: user level usb library" Obsolete. >>> Requested binding: minor. >>> 4.2 Details >>> Solaris currently ships with an implementation of libusb 0.1.8 API, >>> supporting both native Solaris USB and Sun Ray USB frameworks. >>> Unfortunately, libusb development stagnated around version 0.1.12, >>> bound by lack of involvement from the original author and disagreements >>> about future directions. To revitalize development, the community >>> created a fork of libusb, called OpenUSB, and Sun has been actively >>> contributing to the effort. OpenUSB is licensed under LGPL and BSD >>> licenses. >>> >>> OpenUSB provides a set of enhanced APIs for accessing USB devices, >>> providing better abstraction of the diverse USB frameworks available on >>> various platforms and ease development of portable applications. >>> OpenUSB has the following enhancements over libusb 0.1.x: >>> >>> - Redesigned enumeration. New APIs for searching and managing of busses >>> and devices, and notify application of hotplug and power management >>> events. >>> >>> - OpenUSB supports multi-threaded applications (unlike libusb). >>> >>> - Addition of asynchronous interfaces. More flexibility over libusb >>> 0.1.x, all of which interfaces are strictly synchronous. >>> >>> - Support all 4 transfer types: control, bulk, interrupt and >>> isochronous. libusb 0.1.x did not support isochronous or control on any >>> endpoint other than default. >>> >>> - Error code unification. All functions return the same set of error >>> codes across all platforms. >>> >>> OpenUSB includes a libusb emulation layer, implemented via native >>> OpenUSB interfaces, and is ABI-compatible with libusb. Legacy >>> applications will continue to work without recompilation. >>> >>> OpenUSB consists of two parts: a frontend, common to all platforms, and >>> a number of platform-specific backends. This project delivers the >>> backend for native Solaris USB framework. The backend for Sun Ray USB >>> will be added in the near future. >>> >>> This case proposes to mark Obsolete all libusb interfaces from >>> PSARC/2003/721. This case does not remove libusb from Solaris: it will >>> continue to coexist with OpenUSB for some time, at least until the new >>> Sun Ray backend is delivered. >>> >>> OpenUSB applications will include and link with -lopenusb. >>> Planned deliverables: >>> >>> /usr/lib/libopenusb.so.0.0.0 >>> /usr/lib/libopenusb.so -> libopenusb.so.0.0.0 >>> /usr/lib/libopenusb.so.0 -> libopenusb.so.0.0.0 >>> /usr/lib/openusb_backend/sunos.so >>> /usr/include/openusb.h >>> /usr/share/man/man3lib/libopenusb.3lib >>> /usr/share/doc/openusb/openusb_guide.html >>> >>> openusb.h and openusb_guide.html are in this case's directory. >>> >>> >>> 4.3 Interfaces >>> >>> All interfaces in OpenUSB, including structures, macros and functions >>> are Volatile.
