This appendix includes a general discussion of the features in version 1.1 of the Mac OS USB software. In addition, it defines the use of the version 1.1 USPB parameter block that supports isochronous transfers, and it includes some discussion of the feature enhancements in version 1.2 of the Mac OS USB software.
There are significant differences in the features supported in version 1.1 and later of the Mac OS USB software. To take advantage of the new features some modification of existing code that supported version 1.0 Mac OS USB software is required. For information about the required code changes to support version 1.1, see Code Changes Required To Support The Version 1.1 USBPB .
