how to use pc card

[Paul <paula4l@access4less.net>]

I've recently installed debian unstable on my laptop, with 
kernel-2.4.27-2-686.  I have a usb-2 pc card that I want to install.

Under $M, I can plug it in and it will be recognized.  But, to remove 
it, I have to "stop" it, before I can safely remove it.

How is this done in debian?  Is it necessary to "stop" the card before 
removing it?  What deb packages do I need.
