If you camera is not detected when connected to your computers USB port what you can try here first is to connect the camera on a different USB port and make sure the connections and usb cable is fine, and if your computer is a desktop you can try connecting the the camera on the back USB port of your computer and see if that will be fine.
But if still not working I will suggest you try connecting the camera on different computer and also if possible use a different USB cable and reinstall the camera software if you have the setup disc for it.
Try unplugging a few other things like USB hubs before plugging in the camera. If this does not work, please advise what other messages you get when attempting to connect the camera. If you are PC savvy, check out device manager in control panel to see if this gives you any more indication as to what the problem is.
Both the Canon XT 350D and the XTi 400D are recognized by any PC with XP windows operative system. It seems you have to check your USB port or USB cable used to connect your cameras to the PC. Sometimes, the PC does not recognize a specific device connected to an USB port. Yopu can get into the System -device manager screen, and uninstall the USB port, and run the utility to recognize changes in the device manager. This will install the USB port driver again, and if it is a software issue the reason of the problem, then it will be fixed.
Also, you can check your cameras and USB cable in a different PC so you can confirm if they both work has should be.
First, I need to ask the dumb questions:
1. Are both computers running XP?
2. When you connect the camera, do you turn the camera on?
3. Do other USB devices work when connected to the same
USB PORTS you are using to connect the camera?
Ok, since the camera is not recognized at all on both computers, we can
pretty much disregard USB PORT failure, but just in case, try different
USB PORTS on both, please.
Most if not all cameras should be recognized as mass storage devices
just by connecting them to USB PORT on computer, and should be visible
as a new drive in MY COMPUTER icon.
Maybe your bundled USB CABLE is not working, or this is one camera that
insists on using the bunbled software package that came with the
Last thing to try is to buy a multi-card reader/writer and put the memory card in there. That has to work!
This problem mainly occurs because Sony does not support connection though Hubs or for that matter Front Panel USB ports. Try connecting the camera throught the back panel ports (There are usually four to six of these depending on your motherboard.) .
If it still remains unresolved: 1. Update windows XP to atleast service pack two (If you havent already). Uninstall Picture Motion Browser.
2. Uninstall the camera from the device manager. This is how to do it. Connect the camera, wait for it to show as an unrecognised device. Hit "Windows + Pause/Break" to bring up system properties. (Windows is the key next to alt, that brings up the start menu.). Navigate to the hardware tab and choose device manager. Expand the last tree from the list (One for USB devices) and delete the entry "Unrecognised Device" (Select it and hit delete). Shut the device manager. Disconect the camera.
3. Now, connect the camera the one of the USB ports on the back of your PC and power it on. It should show up as a PTP/Mass storage (depending on your camera settings) device.
4. If it still doesn't work, disconnect all other USB devices from your PC and then repeat from step 2.
5. You can reinstall Picture motion Browser if you like or use Xp's photo transfer utility.
I contacted Panasonic and here is what they told me to do and it worked.
"No additional drivers are needed as it runs off the USB drivers imbedded in your Windows OS. That being said though, it is not that the USB ports on the front of your computer are faulty, just that they are in fact a HUB and not the port which is located on the back of the PC. Windows does not traditionally like reading external Hard drives (your camera becomes one when PC connect mode is selected) through a HUB. In this case I would still strongly recommend connecting to the back of the PC."
Not much to add here, except I'd try another usb cable, a different usb port and a different pc if possible.. I've had a number of camera's to connect to pc's, all running xp & never had a problem. Also disconnect all other usb devices when testing. Also connect the camera to the pc, before turning on the camera. Good luck.
Try uninstalling the Fuji software completely, through the Windows control panel. Don't use the supplied software at all. Make sure the camera is unplugged from the computer. Open "my computer" and note which drives are present. Now plug in the camera (still turned off) to the USB port. Turn the camera power switch on. Wait and see if a new drive icon shows up. It may take a minute or so. If you get a new icon (probably Fuji DSC or similar), you should be able to open the new drive and access the images through the various folders. If not, can you see images on the camera screen (when not connected to computer)? If yes, maybe a bad cable. If no, could be corrupted images on card.
is this because i used the usb cable for another devide? - i dont think so. the usb cable that comes with the benQ camera is the usual usb cable. i used it for other devices and still works fine with my camera again. i even used another usb cable from other devices in camera and it works fine.
is it a virus maybe? - well you can try inserting a different device in that usb port, now if it still cant see it, its probably busted. all your usb ports are on used? wow! how about you try taking some of it out and check those ports for your camera.
Do any other devices connect successfully to that same USB port? If no, try another USB port. If yes, when you reinstalled your software, did you uninstall first? If not, see if you can. Once uninstalled, verify that the device is removed via Device Manager. Once removed, if on XP or Vista, try to connect using the built in system drivers. If this does not work, try reinstalling your drivers, but be sure to check for system prompts when you connect. If you do not respond to those prompts, the device will not mount. Let me know how it turns out. DigiChick
