HP Remote Graphics Software 7.0

RGS works very closely with the Windows USB driver stack. Any USB device that exclusively uses
the Windows USB driver stack for functionality should work with RGS. The less a USB device's driver
complies with the Windows USB driver stack, the less likely it will work with RGS.
NOTE: Devices that adhere to the USB standard should work. Because RGS is a remote graphics
protocol and is emulating the USB protocol over a network, devices that are sensitive to timing may
not work at all. This includes USB devices with security and encryption mechanisms built into them.
The additional network delay could be looked at as a threat. Other devices that are known to break
the USB standard, such as webcams, may also not function at all. Performance of USB devices over
RGS will not be equal to that of a locally connected device. File copies may take longer due to the
additional overhead of the network protocol sitting on top of the USB protocol.
HP recommends that customers thoroughly test any USB device they are considering to use with
RGS as Hewlett-Packard cannot certify and or guarantee it will work over a Remote USB protocol.
Because many USB vendors do not support their devices over any Remote USB protocol, HP
recommends that you contact the USB vendor for support concerns first.
Remoting USB microphones
The Remote USB driver (on the local computer) supports the USB isochronous data type, which is
commonly used for streaming data such as that generated by audio and video devices. This enables
certain isochronous USB microphones to be accessed directly by the remote computer in the same
manner as other USB devices.
To remotely attach USB microphones to the remote computer, either of these Remote USB
Configuration settings can be selected:
●
USB devices are Remote—If selected, a USB microphone can be accessed anytime by the
remote computer.
●
USB devices are Local/Remote—If selected, how the USB microphone can be accessed by the
remote computer depends on when the microphone is connected to the local computer relative
to establishment of the RGS connection:
◦
If the microphone is connected to the local computer after establishment of an RGS
connection, the microphone will be a remote device only and can be accessed directly by
the remote computer.
TIP: The Windows Recording devices dialog in the remote computer allows the user to
set the default sound recording device (microphone).
Unique smart card handling
Smart card readers are handled in a unique manner, as follows:
●
Unique smart card handling requires that Easy Login is enabled on the remote computer.
Windows 7—The HP ELO Credential Provider will be utilized.
●
Unique smart card handling also requires that the local and remote computers both be running
Windows.
●
For USB configuration settings USB devices are Remote and USB devices are Local/Remote,
smart card readers will always be accessible by the local computer prior to establishing a
connection to a remote computer. This is to allow the smart card reader to be used by the local
computer prior to using the smart card to authenticate access to the remote computer.
●
The USB devices are Remote and USB devices are Local/Remote settings are effectively
ignored for smart card readers. In particular, the USB devices are Remote setting is ignored as
