does canon have a help number or email address?

On user manual page W-14, have you try to set your camera Communication to
"Normal" instead of "PTP"?
I had problem with photos transfer when I set to PTP, I'm using Windows XP
as well.
Good Luck

Have you got any other Imaging devices (e.g. a flatbed scanner)
plugged in via USB ?

I couldn't get my 300d to be recognised by Windows XP until I
unplugged my Mustek USB scanner. I didn't need to uninstall anything -
I just physically disconnected the scanner from the PC and everything
was OK.

Both work fine now, but I can't have them plugged in at the same time.

It seems the Mustek scanner driver takes over and doesn't allow the OS
to see the camera.

i think canon has a website?
it might have a help number.

it did when I needed it.

It took me 2 hours to download 373 jpeg large photos from 300D to PC.
Anyone know how much time can be save if I use USB 2.0 card reader to do
those download?
Thanks

a firewire cf card reader would be a lot faster

Correction. I just uploaded 1 GB from my camera via USB 1.1.
8 minutes. (81 JPG / 81 RAW / 81 THM).

Cheers,

That exceeds the raw data rate of USB 1.1 (16Mb/s versus 12Mb/s).

Good lord. (I confused my bits and bytes)
That means that if Moore's law keeps up (for flash card read/write
speeds), in a few years a firewire card reader will be faster than USB
2.0 , and the OP will be correct.

I realize that and I was surprised myself. But

1) the card was full (a couple hundred K short of 1 GB) and,
2) it took a little less than 8 minutes to upload and,
3) the USB on my computer is most definitely 1.1.

I don't know if compression is possible in this case? (Using XP, seeing
the camera CF memory as a mounted drive).

Cheers,
Alan

Me neither. But, since the files on the camera flash are 'files', they
could (theoretically) be compressed before being sent over the USB. I
say theoretically because I don't know this to be the fact.

I suspect that

It can't cache what it hasn't seen. The images copied over had been
taken in the couple hours before the connection to PC was made.

Cheers,
Alan.

I would be surprised if that turned out to be the case.

Nothing like trying something...

Cheap (US$15) Apacer USB 2.0 card reader
Slow system by today's standards (AMD 2.4/512MB/ATA100/XP)
Cheap card ("PQI" brand "40X" read speed)
Device "Optimized for Safe Removal" (not "optimized for performance" )

Actual transfer rate achieved: 355 MB / minute.
1 GB over USB 2.0 using cheap and simple hardware in less than 3 minutes.

If you were copying from a USB card reader via PC to an external USB
hard drive, would it slow down significantly?
