light if inserted properly.
Open My Computer, right-click
on the corresponding drive icon,

Never remove the card when
the green LED is flashing.
Wait a few seconds so that the
operating system can recognize the
reader and the available ports, and
then recognize whatever media is
inserted in the reader.
If you do not want to boot from the
media card, remove it during boot
or do not select the option to boot
from the inserted media card during
the boot process.
The bootable USB device will have
boot support if you connect the
media card reader to an available
USB connector on the computer's
system board. If no connector is
available, plug the bootable device
into a different USB port on the
computer.
Reconnect the cable for the front
USB ports. Install the PCI card and
connect the media reader to the
USB connector on the PCI card.
