When You Cannot Connect to the USB
Interface
This section describes how to troubleshoot a problem related to USB connection.
Problem Cause Solution
The machine is not auto-
matically recognized.
The USB cable is not con-
nected properly.
Turn off the power of the machine, re-
connect the USB cable, and then turn it
on again.
Windows has already
configured the USB set-
tings.
Check whether the com-
puter has identified the
machine as an unsup-
ported device.
Open Windows' Device Manager, and
then, under [Universal Serial Bus control-
lers], remove any unauthorized devic-
es. Unauthorized devices have a [!] or
[?] icon by them. Take care not to acci-
dentally remove required devices. For
details, see Windows Help.
