USB 2 question - how long should this take?

Today I finally got around to installing a USB 2 POI card in my older Dell (it already has USB ports of course) running WinXP. The thing is, how can I tell if its really running 2.0, and not 1.1? When I go into the Device Manager, it only says "USB" next to various roots and hubs, but nothing about 2.0.

I timed a transfer of files from a camera to the computer using both the new USB port and a factory port (which is supposed to be 1.1, I thought) and they both took exactly the same amount of time to transfer 975mb of date, about 19 minutes. The old Dell originally ran on Win2000, but earlier this year I upgraded it to WinXP SP1, which I understand has the USB 2 drivers. Could it have turn my old 1.1 ports into 2.0? I also tried the transfer test on my newer Dell (less than a year old) and it also took the same amount of time. So I'm thinking I had 2.0 all the time, but didn't know it. Is this possible? Can anyone who has 2.0 (for sure) tell me how long it takes to transfer almost a GB of data from a camera?

Thanks

It usually takes a few minutes, not 20, to pull 1GB of images from compact flash to my desktop using an USB CF card reader. I don't pull data through my camera. Perhaps it is the camera that has a slow transmission rate.

I agree that it could easily be the camera that is slowing you up. Get a USB 2.0 card reader and plug it in...if you plug it into a USB 1 slot, windows will tell you something like "You have a USB 2.0 device plugged into a slower USB 1 port..."

On my pc with USB2 and a cardreader and a 1gb microdrive it takes about 3.5 minutes to copy 1gb of photos. If you do it through most cameras it will be limited by the speed the cameras sends the data, which is often USB 1 speed.
Cheers,

Often XP will give you a message when attach a device that supports USB 2.0 to something slower. If you don't see this message then it is possible that something else is slowing you down, read/write speed of your hard drive, output speed of the device, ect. Also your older dell's mobo may not support 2.0 so it running the device as a 1.1. Kinda sucks, but doesn't matter too much. Still 19 mins is painfully slow. USB's transfer rates at the slowest should be about 1.5MB/s. If you haven't already try a card reader as NavajoCoast said.


On a side note if you want some real speed look for hardware that says USB2.0 Hi-Speed. If everythings set up right you should be able to pull a gig in a few seconds. [img]/ubbthreads/images/graemlins/grin.gif[/img]

I have both firewire and USB2. They both seem to give me about the same speed.

I agree with everyone who said it might be the camera that was slowing me down, so I decided to try the firewire (I don't have a USB card reader here yet). As you were writing this, I was installing a firewire PCI card into the other computer to be able to use a FW cardreader I bought. When I rebooted the computer, it "found" the FW card, but when I connected the cable to the reader and inserted the card, nothing. Nothing shows up like the instructions say it should (there's nothing else to install - WinXP doesn't need extra drivers). So now what? I think I'm going back to film and a notebook.

I don't have any other USB devices to compare all this, no way to tell on the printer/scanner speed and stuff like that, and my film scanner is SCSI.

Thanks,

Andy,

If you are connecting your D70, it is dreadfully slow USB 1, no matter what you plug it into [img]/ubbthreads/images/graemlins/frown.gif[/img]

OK, this was easy. Solved the FW problem. Bad cord. Fortunately I had just bought a big external HD with its own FW cord, and when I swapped it out, it worked. Just what I needed tonite. Oh, and when I tried it with the card reader, it did transfer the 1gb card in 5 minutes. Can't wait to try a USB card reader next.

Let's see, what else can I discover doesn't work now.....?

Thanks to all.
