I bought this card to have a Firewire connection to connect my camcorder on my new PC. Incidentally I wanted to increase the number of USB 2.0 ports. The card was delivered in a few days. I installed without difficulty (single PCI slot on my PC that also has 2 slots for PCI-Express cards). She was immediately recognized by Windows 7 and since it operates without any problems. I am very satisfied with this product. The card offers 1 Firewire400 port, 1 FireWire800 port and 3 USB2 ports.
