A list of devices on YOUR SYSTEM? Or a list of devices with supporting drivers?

$ lspci -v | grep -i "network"
$ lspci -v | grep -i "ethernet"
$ lspci -v | grep -i "wireless"

$ lsusb -v | grep -i "network"
$ lsusb -v | grep -i "ethernet"
$ lsusb -v | grep -i "wireless"

I'm not sure of the firewire method. For devices that are at least in part configured on your system.

# ifconfig -a

For those with wireless extensions.

# iwconfig

There's a replacement for iwconfig in the works, but I can't recall it's name at the moment. iwip? If you don't have the drivers for said interfaces loaded, they don't show up in ifconfig -a. If things aren't configured just right, you may have a wireless device that reports no wireless extensions in iwconfig. And other quirks.

If you're looking for a list of supported devices, there's several sites that list those. Which vary from driver to driver. If you ID the VENDOREVICE numbers (lspci -n) and google ( on those you generally get hits pretty painlessly.

If you have the lshw command installed, it's even easier:
$ lshw -c network
