How to double Firewire throughput in Win7
« on: October 24, 2009, 01:57:54 PM »

Hello All,

Just a note to share something I learned. I had slow Firewire performance from Windows 7, thought it was kinda strange so I googled and came across this. The tranx speed doubled up immediately, I am hitting 50mb/s for the card reader.

Multiple drivers are shipped with the OS for firewire, the one we are looking for is the "Legacy" driver.

Open Device Manager, Expand your IEEE 1394 Host Bus Controllers and Right click on your 1394 device, then choose "Update Driver Software". On the new windows click on "Browse My computer for driver software", then choose "Let me pick from a list of device drivers on my computer", then select the driver with the word legacy in brackets.

Easy as that! It worked for me as my speed went from 7MB to 52MB by just using the legacy drivers shipped with the OS.
