21. APPENDIX 2 - HOW TO CHECK FOR A USB2 INTERFACE

It is very important that SmartLF Cx is connected to a computer that has a

USB2 interface. USB2 is approximately 40 times as fast as the older USB1.1

standard. Run the Cx Utilities program and press the USB tab to run a check

on the speed of the USB interface to which the scanner is connected.

If the speed is OK and the interface passes the test, SmartLF Cx should

operate in accordance with the published specification.

If the USB interface fails the test this could be due to one of the following:

• This is a computer with a USB1.1 port (a pre-USB2 machine)

• A USB2 port could be available but a USB1.1 device is sharing the connection

• The USB2 port could be faulty or the cable may be too long

• The USB2 interface of SmartLF Cx may be damaged

As an additional check it is wise to inspect the Properties of the USB

interface via the Device Manager of Windows’ Control Panel.

Expand the Universal Serial Bus Controller device. If one of the

USB sub-branches contains the word ‘enhanced’ then the PC is

likely to have a USB2 driver loaded on one of its USB ports.

Unfortunately this does not guarantee that the scanner is plugged

into the port using the USB2 driver.

Computers often have multiple USB ports and some more than

one USB controller. If SmartLF Cx has been successfully

installed on a computer but the scanner connection is changed to

a different USB port (for example on the rear of the computer) this

will cause the driver to be installed again. This is effectively a

new installation.
