5 out of 5 eggsVery Nice Firewire Adapter

Pros: Small;
Comes with both a Mini-ITX and full size bracket;
Wiring is long enough for full size enclosure.

Cons: Wiring can be a awkward to handle if installed in smaller Mini-ITX enclosures (See below).

Other Thoughts: I installed this adapter into a M350 Universal Mini-ITX PC enclosure, which is as small as you can go as far as a Mini-ITX enclosure. It was awkward to route the excess wiring because it's long enough to accommodate full size enclosures. Once I figured it out and hit the button, Windows 8.1 immediately recognized it. Driver software was not necessary. I'm using this adapter for a Firewire audio interface. I'm also using it with a GIGABYTE GA-J1800N-D2H Intel Dual-Core Celeron J1800 SoC (2.41 GHz) Mini-ITX Motherboard Combo. I simply had to cut/file holes in the back plate to accommodate it. So far, an excellent adapter.

5 out of 5 eggsGood product for kernel debugging

Pros: Device works well with Windows kernel debugging of mobile machines (laptops, slate, tablet, etc). Many of these kinds of systems don't have a serial port, and USB debugging is often difficult. By using this 1394 controller, it is often possible to debug these machines.

Cons: Wires too and from device are somewhat fragile.

Other Thoughts: A few things to be aware of if you plan on using this for debugging machines:

1: Not all PCIe Mini 'slots' in a machine actually support PCI signalling. Aften the only support USB signaling for wireless/mobile broadband devices. You won't be able to use this 1394 controller on a PCIe Mini port that does not have PCI signaling.

2: This is a full height PCIe Mini device. Many available ports are for half height cards. You can find bus extender cables to help resolve this problem.
