When you get a CF card reader or something like a 10-in-one card reader, it
attaches to the USB port using either the 1.1 or 2.0 protocol so if your
computer is older you may want to see which you have. I just got a 1.1 version
which will run slower but will run on all my computers. OK on the one end is
the little plug that goes into the USB port on your computer. ON the other end
is a box into which you put the different things to be read. It only connects
to the computer by USB port. It can read and write to whatever media it has
slots for on that other end box. For example, if your digital camera puts your
pictures on a MMC (multi media card) then you put the MMC card into its slot on
the box and it becomes a drive on your PC. If you want to read from and write
to your Compact Flash Card as you do for your Braillenote PK, you would slide
the CF card into its own slot on the box and then it is recognized as a drive
on your PC. I hope this helps you understand. You can buy just about
any of the card readers you come across from the dedicated one that just reads
the CF card which is what I got at Staples because I didn't want to wait for
something ordered from the internet, to something with up to 30 different card
slots for all kinds of differend media you'll probably never come across or
use. You should expect to pay from $10 to $30 for this card reader.
