unable to test all devices. If your peripheral is not on this list, contact your Account
Executive to ask about ClearCube certification services.
• Limit the number of USB peripherals connected to your I/Port. When connecting
more USB devices to an I/Port than there are available ports (three ports on the
I8020/I8820), you need a USB hub. You should select a powered USB hub to reduce the
likelihood of drawing too much power from the I/Port's USB port(s). ClearCube has
observed unpredictable results when simultaneously attaching more than six USB devices
to an I/Port. USB devices with motors, such as CD-ROM or DVD drives, are the devices
most likely to exceed power ratings.
• Occasionally, USB devices fail to enumerate correctly when inserted or removed.
When inserting a device that supports RDP redirection into a peripheral port on the I/Port,
it should enumerate (display as a device on the host desktop). Allow a few seconds for this
to occur. If the device does not enumerate, try refreshing the desktop or the folder window.
This usually resolves the problem. If this does not work, check the system tray for the
device and eject it (if displayed), unplug the device, and then reattach it. Sometimes this
problem is caused by a USB device overloading the power rating for the I/Port's USB hub.
Using an externally powered USB hub will reduce this problem.
When removing a USB device, always eject it from the system tray and wait for
confirmation before physically unplugging it. If the device's icon persists on the desktop
after it has been physically removed, refresh the window or desktop. A reboot of the I/Port
may be required.
I8330 I/Ports
Because the I8330 I/Port requires a connection to be established via the I83xx Admin Utility
or I83xx Driver, certain limitations apply on the usage of I8330s as connection devices.
• Do not use an I8330 I/Port for administration duties. Use a C/Port or an
RDP-connected device (such as an I8820 I/Port or a traditional PC) for host
administration.
The I83xx driver software is supported only on Windows XP. Support on other operating
systems is not available, so the I8330 cannot be used to administrate a virtual machine
(VM) host.
• Do not install the I83xx Driver on a system that also has the I83xx Admin Utility
installed. These two applications are incompatible, and using them on the same system
will cause unexpected results.
• Do not hot-plug PS/2 devices on an I8330 I/Port. On the I8330, PS/2 devices (keyboard
or mouse) are not hot-pluggable. You must turn off the I8330 before attaching or
detaching PS/2 devices.
• Disconnect USB devices using the “Safely Remove Hardware” icon in the system
tray. If USB devices are incorrectly disconnected, the USB chain is forced to
re-enumerate completely. This can cause a delay for the user, and will disrupt any
on-going USB communications (such as printer spooling or file transfer).
• USB devices are not available on the I8330 I/Port until a host connection is
established. Some USB keyboards and mice will function properly when connected using
a USB-to-PS/2 adapter.
