HP USB Virtual Media Interface Adapter Functionality Information

USB compatibility
Because of incompatibilities in various combinations of USB chipsets, composite USB support in server-
class computers, and variances in USB device implementations, issues might arise when attempting to
boot from a USB device directly connected to the server when an HP USB Virtual Media Interface Adapter
is connected to the server or when using a remote Virtual Media session through the HP IP Console
Viewer. In such cases, use a different model or manufacturer of the USB device.
HP Integrity server installations
When installing Microsoft® Windows Server™ 2003 on an HP Integrity server from the Extensible
Firmware Interface (EFI), map only the CD-ROM drive to avoid allowing the installation wizard to choose
the incorrect location of the operating system installation. If a virtual mass storage device is enumerated
during installation, the installation wizard attempts to install the operating system to the virtual mass
storage device rather than the hard drive.
High-speed input devices
The HP USB Virtual Media Interface Adapter is a high-speed USB 2.0 composite device that enumerates a
high-speed USB 2.0 keyboard and mouse. If the BIOS, the operating system, or both do not support high-
speed USB 2.0 keyboards, disable the USB 2.0 function for that server's interface adapter in the OSD of
the KVM switch attached to the server.
Server configuration results
The following table explains the results of the HP USB Virtual Media Interface Adapter based on the
configuration of the server.
Current or previous
selection in the
interface adapter
Current mapped
drives
Action Result
CD-ROM None Initial power up
The interface adapter connects to the USB bus.
When the server accesses the interface adapter, it
reports a keyboard, mouse, and CD-ROM drive. If
the server attempts to access the CD, the interface
adapter reports that there is no media present.
CD-ROM None
A CD-ROM drive
is mapped.
The interface adapter indicates that a CD has
been inserted into the CD-ROM drive.
CD-ROM CD-ROM
A CD-ROM drive
is not mapped.
The interface adapter indicates that a CD has
been removed from the CD-ROM drive.
CD-ROM None
A mass storage
device is mapped.
The interface adapter disconnects from the USB
bus and then reconnects to the USB bus. When
the server accesses the interface adapter, it
reports a keyboard, mouse, and generic
removable media device. The interface adapter
stores the Virtual Media configuration, indicating
that the removable media is presented the next
time the interface adapter powers up.
