okay, it feels like i've looked everywhere to try and solve this problem but i can't find the solution.

my computer doesn't recognise the camera when i plug it in with a USB cable.

things to know:

  • all programs are installed from CD that came with the camera
  • operating system is WinLSD/Windows XP
  • i have tried connecting this to another computer running on the same OS and it worked
  • when i plug in my camera, the computer doesn't even make the usual sound when USB devices are plugged in. it makes a strange one which i assume is the sound for when it doesn't recognise the device
  • i use a 4GB San-Disk SDHC card, i've read about updating the firmware as a means of perhaps solving the problem but do NOT want to do this as i don't want to format my card and lose the 700+ images i've taken
what happens now:
  • i plug in the camera (after everything's installed) and then turn it on
  • "BUSY" appears on the screen
  • then, nothing. the camera screen switches to regular display screen before you take a picture, and nothing appears on the computer screen when what's supposed to happen is EOS Utility opens or the transfer image screen shows up on the camera
  • i open EOS utility manually and the "Starts to download images", "Lets you select and download images", etc, buttons are inactive.
  • i open the peripheral window to discover that my camera isn't even listed on the list as a plugged-in device.
  • i unplug the camera, and the computer makes the sound that it usually makes when a USB device is unplugged (thereby confirming that it knew that SOMETHING was connected)
  • i am left extremely confused

what i don't understand is why it doesn't work on this computer but it worked on the other one when everything was exactly the same.

also: i tried downloading the TWAIN driver from the canon europe website. i double-clicked on the setup.exe after extracting all the files and for some reason it says "PTP file for Windows XP not found" or something.

thanks in advance, i'm SO DESPERATE! :cry:

Go in to the menu settings of your camera, find the "Communication" setting - there are only two choices, switch to the other and try again. At the very least, you should be able to see it as an external drive or similar.

Have you checked the device manger after you connect the camera?

i'm running xp home on mine & i've found the autoplay camera/scanner wizard [or whatever it's called] doesn't recognise the raw files.
i can import directly to lightroom or what i tend to do is click 'my computer' '450d' etc & drag/drop the files into the appropriate folder that i want them in - i used to do this with the old fuji s9500 if shooting raw - then i import into LR or PS etc
i have installed the EOS utility today though so don't know if that will make any difference.

i read this while looking to solve my problem but can't find the Communication setting. where is it, exactly? is there an image online somewhere that i can look at?

Can you download the images via a card reader?

Have you checked the device manger after you connect the camera?

I know what Windows XP is but what is operating system is WinLSD/Windows XP

Try looking here and here from more info on MTP

no, i don't have one :(

yes, that's what i meant when i said that the camera doesn't show up on the list.

WinLSD is like a copy-program or something. sorry, i don't actually know what it is. i'm on exchange in france and this is my host family's computer. normally i would blame my camera not working on the fact that the computer is running on a weird system, but it worked on my host brother's computer which is exactly the same (OS-wise) as this one, so that can't be the problem.

thanks, i'll have a look :)

thanks for trying, but unfortunately the computer doesn't seem to recognise what the camera is in the first place :(

note: i forgot to mention, i tried hooking up the camera before installing anything (to see if it would work) and the computer DID recognise it (it asked me to insert the installation CD for the Canon EOD 450D camera).

Try this:


  1. Create a new folder on drive C named Camera.
  2. To download updated WIA drivers for your camera model, visit the following Canon Web site: http://www.usa.canon.c​om/consumer/controller​?act=DownloadIndexActexternal link (http://www.usa.canon.c​om ...ller?act=DownloadIn​dexActexternal link)
  3. Save the new driver file to the C:\Camera folder.
  4. Click Start, click Control Panel, and then double-click Add/Remove Programs.
  5. Select the Canon camera software, and then click Remove. Repeat this step until all Canon camera software has been removed.
  6. Disconnect all Universal Serial Port (USB) port devices except drivers for the keyboard and mouse.
  7. Restart the computer to make sure that all driver files are unloaded from memory and removed.
  8. Open the C:\Camera folder and then double-click the driver file to start the extraction wizard. The wizard will default to the C:\Windows\Desktop folder. Note Do not use this default folder. You must specify the C:\Camera folder on the Extract to command line.
  9. Extract the files.
  10. Open the C:\Camera folder, and then open the English subfolder.
  11. Double-click Setup.exe to start installation.
  12. Connect the camera to the USB port. After the computer detects the camera, you may receive an error message similar to the following: windows image acquisition service error system cannot find file specified, "imaging."


    Click OK in response to this message.
  13. Click Start, click Control Panel, and then double-click System.
  14. On the Hardware tab, click Device Manager.
  15. Expand Imaging Devices. The camera should now be listed.
  16. Right-click the camera name, and then click Properties.
  17. Click the Driver tab, and then click Update Driver.
  18. Click to select Install the software automatically (Recommended), and then click Next. The new driver files may be located in the C:\Windows\Twain_32\Ca​nondc folder. Click Next to finish the wizard.
  19. Disconnect the camera from the USB port.
  20. Restart the computer to make sure all new driver files are loaded into memory.
  21. Reconnect the camera to the USB port of the computer. A Choose Application window will appear to ask what program to use for imaging.
Other questions:

What service pack do you have installed with XP?

Have you do things in the order as on pages 146 to 150 of your manual?

I don`t have a 450D myself, but I suspect he may have given you some wrong info in error.

i've gotten up to step 2.

i get this when i select Windows XP: No drivers are available for this selection. This operating system may not require a driver or, in the case of older operating systems, may no longer be supported.

edit: i'm going to try downloading the one that's listed under Windows 2000: "Canon EOS PTP TWAIN Driver 1.7.0"

edit 2: getting same message as mentioned in my first post.
"PTP Driver file for Windows XP not found. Click [OK] to cancel the installation"

SDHC readers are $5 shipped on ebay. Just get one and forget about all the software crap. Insert SD card, Plug it in to USB port, copy files, delete, done.

Good point, but it still would be nice to crack the problem
