The USB-00 product, version C.01.05.00, delivers the USB subsystem and device drivers.

Summary of Change

What’s New for Customers Migrating from HP-UX 11i v1 September 2005?

The USB stack and drivers delivered in USB-00 replace the legacy USB stack delivered in drivers hcd, hub, hid, and usbd.

USB-00 delivers all the functionality of the legacy stack plus the following features:

  • Support for plug-and-play of USB devices.

  • USB Bulk Only protocol, SCSI pass-through mass storage driver (this includes but is not limited to USB CD-ROM/RW and DVD-ROM/+RW, and flash memory devices).

  • Device file system for dynamic USB device special file creation/removal.

  • Boot/install from a limited set of HP-branded USB DVD devices.

  • Support for HP keychain drives.

  • USB mass storage device encryption.

What’s New for Customers Migrating from HP-UX 11i v2 June 2006?

USB-00, version C.01.05.00, includes various quality improvements from previous releases, a dynamically managed device file system enabled by default, multi-layered USB mass storage encryption support, and device tracking.

Impact

All USB device special files will now appear in the device file system. Customer scripts and programs will need to be modified to use the new device special files.

Compatibility

This USB product will not be compatible with any application that accesses human interface devices (HID) through the legacy HID device special files in /dev/hid. The device special file for USB-00 supported devices is located under /dev/deviceFileSystem. For more information, please refer to the Device File System Users Guide available at http://docs.hp.com/en/7407/DevFSUsersGuide.pdf

Performance

The Device File System greatly improves total customer experience, as well as mitigating the risks associated with attaching a different USB mass storage device to an existing device special file collection.
