USB-00
The USB-00 product, version C.01.03.01, delivers a USB infrastructure and driver
package to support keyboards, mice, and HP DVD boot for the HP BladeSystems.
Summary of Change
USB-00, version C.01.03.01, includes various quality improvements from previous
releases, a dynamically managed device file system, and USB mass storage encryption
support.
Impact
USB-00 delivers a new subsystem for dynamically managing USB device special files.
The Device File System is not enabled by default, but you can optionally enable it by
referring to product documentation (see the following “Documentation” section).
USB-00 also delivers a utility to encrypt USB mass storage devices, usbencrypt (1), that
allows the user to control access to a USB device. For more information, please refer to
the usbencrypt (1) manpage.
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 files for USB-00 are located in /dev/deviceFileSystem. For more
information please refer to the HP-UX Device File System User’s Guide, available at
http://docs.hp.com/en/7407/DevFSUsersGuide.pdf.
