Summary of Change
To enable USB DVD boot functionality on Itanium-based servers, USB-00 version
C.01.00.00 is now available as an always-installed product in the HP-UX 11i v2
Operating Environments.
NOTE Please note that this current revision of the USB product will only be qualified with
Itanium-based HP servers, and does not support PA-RISC architectures.
The new version of the USB selectable product differs from its previous versions in the
following ways:
• It co-exists with the legacy USB stack in a kernel image. In this case, the legacy USB
stack is disabled, and the new USB driver handles all USB traffic.
• It provides a mass storage driver for HP brand USB 1.1 DVD drives for boot install
only.
• For this release, USB-00 does not provide multi-seat or multi-head functionality. If
you require this functionality, you should revert back to the legacy USB stack. The
device special files for USB keyboard and USB mouse are
/dev/deviceFileSystem/keyboardMux and /dev/deviceFileSystem/mouseMux,
respectively.
•For this release, USB-00 does not support USB hubs. You should revert to the legacy
USB stack.
• PA-RISC architectures are not supported, but it is safe to install this bundle on
HP-UX 11i v2 PA-RISC systems.
NOTE The PA-RISC flavor of this bundle is intended as a product template for future
revisions. It removes any previously delivered PA-RISC versions of USB-00, which
were delivered for special use, from the system. It does not provide any USB
functionality.
