Windows 7 computer doesn't recognize phone when attached with USB cable

USB hard drive is a portable external storage device that works just like a conventional hard drive. The device is simply plugged into a USB port on your computer as you would connect a flash drive. Unlike a flash drive, however, a USB hard drive can store a much larger amount of data. If your computer will not recognize your USB hard drive, you can try troubleshooting steps to resolve the problem.

Plug one end of the USB cable into the port on your hard drive and plug the other end into the USB port of your computer. Ensure that both ends of the cable are connected securely. Open "My Computer" (Windows XP) or "Computer" (Windows Vista/7). The USB device should be listed as "removable disk" once it is plugged into the computer. If it is not listed among the available drives on your computer, proceed to the next step. Ensure that the data cable is working properly. Try another USB cable if you have one available. Disconnect all other USB devices from the computer as they may interfere with the operating system detecting the external hard drive. Reboot the computer if the USB hard drive is still not recognized. Plug the USB cable into another USB port and check to see if the device is detected. If you are using a USB hub, remove the device and plug the external hard drive directly into a USB port. If the computer still fails to recognize the device, the external hard drive itself may be experiencing a hardware problem. Check the status of the hard drive in the "Device Manager" window. Under Windows XP, right click "My Computer" and select "Device Manager." For Windows Vista and Windows 7, click the "Windows" button in the lower left corner of the screen, then type "Computer Management" in the search bar and press "Enter." Select "Device Manager" in the "Computer Management" window. In the Device Manager window, click the "+" sign that appears beside "Disk Drives." If the external drive is not listed, click "Other Devices" in the Device Manager window and see if an "Unknown Device" appears. The external hard drive may have been detected but the device is not working properly. If it is still under warranty, take the device to the computer store where it was purchased to have it repaired or replaced. Hope this helps.

after plugging in the USB cable to the camera and computer you need to set the mode button on the camera to "setup". Then the USB will be recognized and you'll be able to see your drive and pictures. I had the same problem then went and re-read the instruction manual... when in doubt... READ :)

First, try attaching the camcorder via usb cable with the camera OFF, then turning it on. This may trigger Windows to activate the driver scanner and activate the driver. If you've been attaching with camcorder off, try attaching with it on, to see if that activates driver installation.

If that doesn't work, you may have a low-power usb plug; often the usb ports in the back of the computer put out more juice than the handy ones on the front. You may also need a shorter and more robust usb cable; I've found with various cameras and phones that certain usb cables work fine for recharging but won't necessarily provide adequate data transfer.

This Camcorder does not support USB streaming with the Windows 7 Operating System. Use an i.LINK cable to transfer the video to the Computer. The i.LINK port is also called IEEE 1394 or Firewire port.You can use any video capturing software like Windows Movie Maker to transfer the video from the Camcorder to the Computer.The Firewire to USB cable won't work with your camcorder,you will always end up with this error.
Click the link below for the instruction to transfer the video to the Computer using i.LINK cable.

If you are using a Windows XP Operating System then you have to install the USB Streaming Driver in the Computer from the supplied Software disk with the Computer.
Check this Link for the instruction to transfer video to a Computer using USB Streaming.

If you do not have the supplied Software disk then I suggest that you use the i.LINK cable to transfer the video.
Please let me know if you need further assistance on this issue .

If you connect CyberShot Camera from a USB Cable, check the cable once. If that doesn't solve the problem, Choose Mass storage option from the Camera Menu when prompted. I think it should work.

Try using different usb ports on your computer. If it doesn't work then try hooking up your iphone to another computer. If it still isn't being recognized then try a different IPHONE USB cable.
If your Iphone still can't be recognized after all of this then read the article at the link below.

Also try restoring your iphone to factory defaults if necessary. This is a last resort. If your iphone still won't get recognized by the computer then it could be the connection on the Iphone is defective and in that case replacing the phone is the only option.

click start right click on computer select properties then on device manager look through all of your devices if you see a yellow question mark?or exclamation mark ! or red x
right click to reinstall drivers or
if you can see your usb but its not working
ports(com&lpt)right click update driver
sometimes the wires inside the cable will be damaged due to bending or stretching or placing heavy equipment upon the cable,
just replace the cable of the hard disk, when you plugged the external disk drive you got that windows could recognize the USB device change the cable everything should work fine again,

check the USB leads that attach to the motherboard usually red-white-green-black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems also make sure the computers Ram and Cmos battery are securely seated
if this fails to fix the problem
you might have to install a usb 2 or 3 card they are cheap and easy to install you can buy these on Ebay very cheap
hope this helps

Unistall any previous you have installed for your device.

The Driver for Your Product Is Included in the Windows 7 Operating System (i.e. Win 7-32bit & 64bit).
Simply connect the printer to your computer with a USB cable, and Windows Update automatically installs the driver for your product.

Hope it helps.

HI there,
I've personally gone through this circle...ugh.
First - Reboot your computer, and your cellphone. Turn them both completely off, and back on.
If that doesn't solve it,
Second - UNinstall everything to do with your phone. Drivers/Software/Etc. Once that's done, Reboot your computer. Now reinstall the drivers/software/etc, and when that's finished, plug your phone in, let windows find and install what it needs to.
If THAT doesn't work,
Sometimes windows installs your phone as a modem, and then as a usb disk. It may be possible that you machine recognizes the modem first and runs a process to coincide with that. FInd that process and kill it, and you should be good to go!
