I was using a USB 2.0 port on a Gateway 5252, which has a dual core CPU running at 2400MHz. To show this here are the results of some speed tests I did.

Some card readers are fast, others are slow. The speed issue depends on the card speed, the camera and the card reader. I can't say I have had problems, but I know others have. If direct connection works, then it's fine, but I see lots of complaints about the connection failing or refusing to connect in the first place. It also seems to be true, based on reading photography forums, that people have a lot more problems with direct connections than with card readers. Personally I find it easier to plug my memory cards into a card reader than to connect my camera up to my PC whenever I want to transfer an image. So what difference does it make how you download the images, as long as you download the images? Well there are two factors here. With the EOS 40D it only shows JPEG files, not RAW files.

It only allows reading of image files, not writing to the device.
#Compact flash card readers drivers
This is done via the Windows Image Acquisition (WIA) drivers which are part of Windows XP (SP2) and Vista. This is certainly the case with the EOS 40D and Windows XP. Some operating systems (such as Windows XP) will recognize when a camera is attached to the PC and will allow some types of images (JPEGs) to be downloaded.
#Compact flash card readers driver
no driver or other software needs to be installed.Ī few cameras will show up as an external drive when connected to a PC, though I don't believe that any of the Canon EOS DSLRs do that, at least not easily and without additional driver software. With most modern operating systems (windows XP, Vista etc.) the card readers are "plug and play", i.e. Then use the normal file copy or move commands (or drag and drop) to transfer your images to a directory (folder) on your computer. Connect an external card reader to your computer (usually via a USB or Firewire port) which sees your memory card as another hard drive on PC.Connect your camera to your computer (usually using a USB port) and then use software which came with the camera to download the images.Once you have shot images with your digital camera, you need a way to get those images onto your computer.
