USB cable faulty
Change the USB cable.
The PC recognises the
Reader, but claims that it
is faulty in the Windows’
Device Manager
and
does not create a
network connection
Windows has previously
marked the Reader as
faulty and will not try to
connect to it or load the
Reader driver. Usually
caused by rapidly
unplugging and plugging
of the USB cable.
Make sure that the USB cable is unplugged and the
Reader is turned off. Remove/Unistall the faulty device
from the
Device Manager
, then plug the USB in, turn
the Reader on and wait for a network connection again.
Alternatively you can connect a different Reader to the
PC as it will have a different serial number and
Windows will not flag it as faulty.
The Reader is connected,
and appears to be
working correctly but the
network connection drops
out after a few seconds
A Reader was replugged
too quickly before
Windows
finished
processing the previous
network connection
Wait at least 30 seconds before replugging any Reader
into the same PC or wait until the network connection
disappears.
USB hub does not work
properly
Power cycle the PC. Try a rear USB port on PC to plug
a USB cable. Avoid using an external USB hub.
No network connection
can be made to a Reader
but the

window
shows that the Reader is
connected and all other
network
status
information indicates that
networking should be
working
The USB port on the PC
has stopped working for
an unknown reason.
Use another USB port. If this fails, power cycle the PC.
