Necessary to remove 1394 driver before downloading new driver?

Seems rather old. Can someone confirm this is the correct driver? I'd suggest installing the previous device drivers in the Compatibility Wizard. In addition, you can use the Windows XP driver for testing. If the problem still persists, please understand that Windows 7 is a new operating system only the beta version and whole driverstore has been reprogrammed; some old driver is not compatible with new OS. I suggest that you should wait for another period of time till the retail version is released and push the vendor company to upgrade their device driver.

If a node sets both of the bits in the speed sp field in the self-id packet, then ohci.

If the speed field contains any other value, then ohci. The gap count value that is used is based on table E-1 in the IEEEa specification, which provides the gap count as a function of hops. You can change the default gap count behavior by using a registry value. In Windows 7, the DDIs were changed to support faster speeds as defined by the b specification and improved to simplify the development of client drivers.

If you need to buy a Firewire card for your computer, unless you have a specific need for a Firewire port, I strongly recommend you buy a Firewire card with just Firewire ports.

Otherwise, the Firewire Driver will not see the Firewire port, as the driver looks for a Firewire chipset. Firewire Cards If you don't have Firewire port on the motherboard, they you will need to add a Firewire expansion card into one of the slots on the motherboard. While the Firewire cards are backwards compatible with the Firewire cards, I don't recommend using the Firewire cards for video capture.

When I tested the Firewire cards, they did not work for video capture, but they did work when connecting a scanner to them. So for video capture, stick to the Firewire cards. If the Firewire card comes with drivers, do NOT install them. You will need to install the Microsoft Firewire driver from this web page.

Check your motherboard to see what types of expansion slots you have. So be careful when purchasing a Firewire card that you buy the correct one for your motherboard. Firewire Cards Below, is a photo of two Firewire cards that I strongly recommend to use.

They are both PCI-E Firewire cards and are basically identical, one has 3 ports and the other has 4 ports. They are sold under various brand names on Amazon.

These are the cards I use here at Studio 1 Productions. I have them pictured below. That is not true anymore. I have tested over a dozen Firewire cards and the cards with the VIA chipset, like shown below actually worked better than the cards with the TI chipset. The TI chipset are found on the more expensive cards, but they don't seem to work very well in Windows The above cards have both a Firewire 4 pin and 6 pin ports.

When you buy a Firewire card try to find one that looks the the photos above. Remember, they are sold under various brand names. Firewire Cards Below is a picture of a Firewire card. As you can see in the picture, the Firewire cards have a power connector that you need to connect to your computer's power supply.

If you don't connect a power supply connector to it, it will not function properly. NOTE: Firewire cards do not have or need a power supply connection. Beside the Firewire cards giving us problems for video capture, other people have had reported to us that they had problem with video capturing with Firewire cards. I tested the 12 different Firewire cards, most of them were identical to the ones in the pictures above, they were just being sold under different brand name.

No matter what I tried, I just could not get them to work with these devices. They would only connect to the Sony DSR editing deck. The TI chipset cards gave me so many problems, so please stay away from them and only get the VIA chipset card.

We could not get either Firewire cards to work with video capture. But they did work with an older scanner. What about a Firewire to Thunderbolt adapter? It will only show up as a Thunderbolt port in Device Manager and not as a Firewire port. As I stated above, the Firewire driver looks for a Firewire chipset on either the motherboard or on an expansion card that is plugged into one of the slots on the motherboard. I have talked to about 14 different people on various forums about capturing MiniDV footage this way and only 2 people said they were able to get this to work, everyone else were unsuccessful.

I recently tried using these adapters myself and I could not get it work. So I don't recommend wasting your money and time on Thunderbolt adapters as a way to capture video from a MiniDV camcorder or MiniDV editing deck, they don't work for that.

Most video capture software or audio processing software or scanner software need to work directly with the IEEE Firewire driver and the Firewire driver will never see a Firewire port chipset since it is not built-in to the motherboard or installed in an expansion slot. With all of that said, I have seen people who have used the above adapters to connect an external Firewire hard drive to a computer via the Thunderbolt port, with success.

These adapters do NOT work for video and audio transfers. FireWire transfers data as a steady stream, while a USB connection transfers data as packets and thus they are not compatible. While there are Firewire to USB hubs not adapters as shown below , these are more expensive than a FireWire card for your computer and some users have complained that the hubs are problematic.

Users have reported that they have electrically damaged the Firewire port on their camera or electrically damaged the USB port on their computer when attempting to use a Firewire to USB adapter. Firewire Ports that are built-in to the Motherboard. You will need to make sure this is set to Enable or ON. Some software only allow you to work with footage that comes from an SD card or from the Hard Drive. We use Vegas Pro and Vegas Movie Studio and both of those software packages support capturing video through the Firewire port.

Make sure what ever video capture program you are using, that you turn off the Device Control in the video capture program. If it is not turned off, you may run into problems trying to capture the video footage.
