Locate the green light under USB that corresponds to the USB port to which your
USB device (e.g., printer or scanner) is connected.
Status Condition Suggestions
Off
The UBox does not have power. Check the UBox's power supply and its connection to
an outlet.
Blinking may indicate the UBox
hardware does not support your USB
device or is having problems
communicating with the device.
Currently, the UBox does not support isochronous
USB devices (e.g., webcams and USB speakers).
If you have a USB device that is not isochronous,
please check the Lantronix web site or contact
Lantronix Technical Support.
Note: While most USB devices work with the UBox,
future software updates from Lantronix will support
certain incom
patible USB device. Please go to the
Lantronix web site or contact Lantronix Technical
Support for more information about compatible
devices.
Blinking
Blinking may indicate you have
exceeded the number of USB devices
per UBox.
One UBox supports up to eight USB devices. While
many USB devices appear as one USB device,
components of compound USB devices (a device
with an embedded hub or a device that has multiple
components tied together by an internal USB hub)
count as one device each.
For example, the Lexmark X1150 is a compound
device that has two components (one for the scanner,
one for the printer). The Canon i475D is a compound
device that has three components (the printer, the
card reader, and an HID device for buttons on the
printer).
If you connect four X1150 devices, you are still under
the eight-device limit, and the USB lights do not blink.
If you have three Canon i475Ds, you have nine USB
devices and are over the limit. Therefore, the light
blinks.
On
This is normal and indicates the UBox
supports your USB device.
Proceed to the next light.
