The computer can not detact the camera or scanner. even the device is turned on

There is only one solution but I don't think you are going to like it !!!
Camera shop Time.

kindly check your hardware its working on not check by hardware detaction tools downlode by google ,& check hardware name .& driver version .

The first step will be to check to see that your computer recognizes that anything is detected. to do this you should:

1. Open your Control Panel (Make sure it's set to "Classic View")
2. Click on "System".
3. Go to the Hardware tab and click on "Device Manager".
4. If your computer does recognize the camera, it should show up under "Imaging Devices".

If it does not, then it should show up under "Other Devices".

1. Right click on the camera there, and click "Update driver"
2. Now, follow the on screen instructions, and windows should get your camera working.

If your camera is recognized, but still doesn't show up, then you probable have a problem with whatever program is trying to use it. For that, I would need to know what program that is.

Hello,

Seems like your trying to use the camera from a shortcut? Instead, connect the camera and turn it on, if the screen of the camera has a selections creen, select PC or similar.

Then open my computer or computer from either desktop or from start menu.
In my computer you should see the camera or a removeable storage device, inside you will find all the pictures of the camera.

please let me know if you need further assistance.

ok this problem is caused by the wrong drive installed for the Crystal Eye Web cam.

even thoguh the camera shows that it is installed, the application looks for a specific one for the model you have. Unfortunatly Acer used 3 models of the camera without telling you which you have and calls all of them "crystal eye web cam"

go to acer.com select their support section and download all driver and applications available for the camera. you will need to try then 1 at a time til you get the one that works for your system

When this is done check device menaged and you will find composite device under Universal serial bus controllers.Right click on composite device and select "update driver" then select "I will select driver to install myself" and then browse to the folder with camera driver. Camera driver will be installed and issue sorted!

Check if your camera can support a 4G card. Some don't support than 2GB. if it supports, re-insert the card.
PS. If you have a card reader. Formatting once from your computer can help.

If you are running windows xp then unplug your camera from the computer. Turn the camera on and press menu. go to the setup tab and go down to usb and make sure that is set to mass storage. Then go ahead and plug it back into the computer. Turn the camera back on and see if your computer will come up with asking you what program you want to use. If it does make sure you select "scanner & camera wizard" and that will save your pictures into a my pictures folder for you.

is your computer connected to scanner?? if so remove the scanner and deactivate the scanner software in computer then the problem will not come.
