Do I need to install a driver for a D-Link DGE-530T PCIe card? I plugged in the card (support link) and restarted Ubuntu.
1) Do I really need to install a driver for it or there is native support already?
2) How can I check if the hardware is ready to use?
dmesg
-- look for something related to your card there, then you may get a hint about its status.
