Converting USB 2.0 Hardware to Firewire

I read a post somewhere on the Internet saying that it's possible to convert USB 2.0 devices to Firewire. The solution for this is to buy a Firewire hub and connect USB devices to it and have the hub connect to the laptop via the Firewire port. Is this possible?

Is it possible to connect USB 2.0 devices to Firewire port? Is so, how would I go about doing this?

 

I found some adapter cables here. But may I ask why you need to convert USB to Firewire when their speeds are so similar?

 

His computer may not have a USB 2.0 port, possibly only USB 1.1; he might already be using up his USB 2.0 ports; etc.

Additionally, FireWire is available in 400Mbps and 800Mbps, whereas USB 2.0 is only 480Mbps (if he only has USB 1.1 available, that's just 12Mbps). Either way, even FireWire 400 is generally faster than USB 2.0, due to the way they were designed -- USB will never get close to 480Mbps. Sustained throughput of FireWire is much, much faster than USB 2.0.

 

Here's the reason for converting USB 2.0 to Firewire ports:

Since I only have 1 Firewire port, I thought I would be able to connect my USB 2.0 devices such as an external hard disk drive and other devices to this port.

Has anyone used the following USB/Firewire hubs? What is your opinion regarding these hubs?

I assume it's possible to convert a 6 pins Firewire connector to a 4 pins Firewire connector. Is this assumption correct? I need to do this because many external devices are built using a 6 pins Firewire connector. Because I want to connect these devices to the Firewire port on my laptop which has 4 pins, I need to convert this 6 pins firewire plug to a 6 pins firewire plug.
