    I have a 1.6 Powermac G5
    I use a sandisk 6 in 1 memory card reader. its a USB2 reader
    I use some compact flash cards that I read and write from
    on my G5 it runs at USb1 speeds

    when i plug the reader into my dads pc laptop it screams at usb2 speeds

    I am directly connecting the reader to the front port on my G5

    Any suggestions?

    Shouldn't be - according to this all the USB ports on the machine are USB2.0. I have to admit I thought the front one was 1.1. I know that doesn't help the OP who should try it anyway :)

    That's very strange. It could be the USB flash reader, but you should try using the back ports as mentioned above and see if it makes any difference.

    What's the brand? Many USB storage devices are picky (some brands of Flash drives performed horribly on Macs in a recent review, for example, while others offered great performance [Sandisk's was one of the best, I think]).

    480Mb/sec is USB 2, why Fat16?
    Does the camera recognize FAT32?

    Transfer a big file on both systems and give us particulars.
    If nobody can come up with a solution to your problem, it at least gives some hard evidence for people to look up later.

    What I would do...

    Hmm... what I would do is back-up all important things on the card, reformat it, test the speeds. If they are faster, I would keep it that way unless the Canon doesn't recognize it, in which I would reformat it back.

    :eek:

    The thing that you have to understand that you are doing much more than just transporting data. You are also reading, writing, and verifying data. Flash drives are not terribly fast. You also have to be very careful when comparing Windows speeds to Mac speeds. The data copy is complete only after the little LED on your flash drive stops flashing.
