Firewire to USB 2.0 adapter?

I'm pretty sure that it does mean that all packets are sent at 480. When there are multiple devices, they just take turns sending packets. Individual packets do not slow down.

I am saying that you allow less turns to the device, not that you slow down the packets.

I think you're right about the inherent similarities between FireWire and SCSI. http://en.wikipedia.org/wiki/FireWire.

I've always thought that was a fair comparison.

FireWire :: SCSI (High performance comes with low CPU load, daisychainable, $$$)
USB :: ATAPI (performance comes with moderate CPU load, limited device connections, $)

I thought USB and Firewire had the same amount of devices to be daisychained. It's been so long since I even thought about that.

At any rate, has anyone ever seen someone with more than 5 or 6 daisychained devices? That would be an interesting mess of cables.

That's BS. I'm sure people would have a use for this. Even if there was little demand, you'd still be able to find it somewhere. I think you are just trying to troll around. It's just not possible.

There's no FireWire/SCSI controller faster than 20 MB/s for a lack of adequate controller chips. The market needs to be huge if you have to make an affordable new IC (and if you want to implement an ASIC or FPGA for a smaller market, how much would it cost?). This could be the block.
 
Q Is USB and Firewire the same thing?
A No. Although they provide similar performance, they operate completely differently and are not compatible.

Q Is there an adapter to convert Firewire to USB so I can plug a Firewire device into my USB port?
A No. As mentioned above, they are not compatible and conversion devices are not (as far as we are currently aware) available.

Q: Can I convert Firewire to USB?
A: NO!!!! If you wish to connect a Firewire device you will need Firewire Ports on your computer.

There is no such thing, because FireWire and USB are completely different standards; you can't convert the flow of data of one of them into a flow of data for the other.

The two technologies are not integrated, and it is not possible to connect a USB device to a Firewire port either directly or through the use of a Firewire to USB adapter.

How about a SCSI to Firewire to Serial to Ultra/133 then over to the DDR2 memory bank then back to PCI?

Just kidding.. :)
 
this is so silly, is usb to firewire, firewire to usb possible? 100% yes, is there any demand for it almost 0, why do we know this, because most devices come both, who would buy a 100$ usb burner then a firewire to usb converter? instead of buying the right drive the first time? very few people, the demand is almost zero, no profit = nobody making it, its that simple. there are firewire to scsi, usb to scsi, firewire to ide, usb to ide, if there were more then a few people out there who wanted this silly device we would have them.
 
I'm in the same sort of boat, having gotten a USB2 external HD for Christmas but being on a 5-year-old Powerbook with no USB2 capability.

Someone I know wondered if this would take care of it. I said it didn't sound like anything would, and there are other hubs for both that say they don't convert, but he thought this was different. Thoughts?

And if all else fails, anyone want to buy an NIB, mint 120 GB drive? :D

No, No, No, No, No. Zero percent possible.

Those hubs do not convert. They are merely two hubs (1 FW and 1 USB) in one box.

grapes911,

Never say never. I'm sure a Firewire to USB converter is possible. It just depends on what your definition of a converter is. For example, I can hook up my iBook to a USB drive and a Firewire drive and copy from one to the other. In this case, my iBook is a USB to FW converter.

Of course, a Mac is a little bit of overkill for what we're really talking about. But really, how hard would it be to design a converter with the necessary hardware to allow for USB to FW connections? Sure, it'll probably cost more than a simple USB to Serial adapter, but if there was a big enough market, someone might make it.

If you read the entire thread, you'd see that I already said:
The bridge would require a processor to do conversions, memory to work with, probably a hard drive for a buffer. Basically, you'd need another computer.

It has got to be possible.

It has got to be possible. That is what I am doing with my two external hard drives. I have a USB 2 drive daisy chained into a firewire drive into my computer. Works great. So it must be possible.
 
Usb to Scsi scsi to firewire ?

is it possible to get a USB to Scsi converter than use an Scsi to firewire converter?
