WEP cracking

I've always heard that WEP keys are easy to crack, and I was wondering if it would be possible to do so using some (very) old hardware I have lying around.  Specifically, all I have available is a SMC2632W PCMCIA card, a WUSB11 linksys usb network adapter, a quite old laptop, and a decent desktop. 

When I look at the software and information I can get from google, everything seems simple except capturing the traffic to analyze.  Are there any utilites (windows drivers or a linux build) compatible with my wireless card, or is it impossible?

Any help will be appreciated, thanks. 

Get a PCI or cardbus Wireless adaptor on netstumbler's HCL.  In general, it's best to get a specific card if you want to do some hard core wardriving.  It's too difficult for them to write drivers for every single wireless card in existence, so you'll have to meet them halfway.

Another thing you need to do is to catch someone transmitting data on the wireless network.  That's the only way that the IV's that your software can crack will get sent out.  Just being able to see it doesn't mean you're catching IVs; if no one is using the network, all you'll be getting is the ping signals the access point sends out to advertise the existence of the network, and those aren't encrypted, so naturally you can't use them to decrypt anything.
