Says USB port problem...on 3 different computers

You don't need to have a driver for your external HDD to work.

You have three possible problems:

1. USB port (software problem) - outdated USB driver or with bugs

Try updating them via the device manager. Or you can try uinstalling it then scan for hardware changes. It will automatically reinstall.

2. USB port (hardware problem) - try a different USB port.

3. HDD defective - You may want to try connecting it to a different computer. If it doesn't work in a different computer then it should be defective.

Try a different USB device on each of the USB ports on your computer.
Hopefully, all your USB ports are working correctly.

Try a different USB port on your computer.
Hopefully, the SanDisk will be detected on one of the ports.

Try a USB port on a different computer.
If the SanDisk still is not detected, then spend $10 to buy a new 4GB flash-drive.

There are few possibilities. 1. You device is broken 2. You usb port is broken 3. Your device was previously installed on different port and now windows cant recognize it on this port.
Solution: Try to plug in your device to different usb slot.

Well, it probably does have a problem if it worked on this same computer before without a problem. You could try the memory stick in the following to isolate the source:

1) try in a different USB port (to see if it is USB port related - only this port has failed - others ports will work).
2) try in a port on a different USB controller (to see if it is USB controller related - all ports on this controller will fail. Other ports on other controllers will work).
3) try in a different computer (to see if it is related to the USB stick itself ).
4) repeat the process with known good USB device such as a mouse or other storage device (this will confirm or cast doubt on the results found above).

That's about all you can do. Retire or replace the source of the problem. I hope thgis helps - good luck!

Hi there, If you haven't already done so... Try connecting to a different USB port, or on a different computer. I noticed on my brothers computer, that when I use one USB port - doesn't work, but the other one does (probably something faulty inside on one of them). Also can try connecting using another different cord...
Hope you can get connected... ****.

did you mean that your computer does not detect your camera when you connect to it? How do you connect your camera to the computer? by usb port? try the following, one by one:

1. check by connecting to a different USB port in your computer.
2. check by using a different USB cable.
3. check by connecting to a different computer.
4. if your camera came with a disc - install it in your computer and then try again.

which operating system are you using - XP? Vista? Win7?

1. Connect the Reader to a different USB port of the Computer.
2. Connect the Reader directly to the USB port of the Computer; dont use any USB hub or adaptor to connect the Readr to the Comp.
3. Disconnect the Reader and then press the RESET button.
4. Try connecting the Reader to a different Computer to check whether the USB port of the Computer is working properly.
5. If the issue still persists, service may be required. Follow the below link to initiate the repair: http://eservice.sony.com/

My flip mino hd USB also will not plug into my MacBook Pro.  I've tried it on 3 different machines and it will only fit into one port, and not at all easy into that port.  When I look at the USB connector on the device, there appears to be slight raised plastic ridged on the outside ends of the connector.   

Do you see a message on your system tray when it is plugged in? If you don't see any message, it means that the drive is not being detected. You can't retrieve any data or files on the thumb drive if it is not detected. Things you can try to isolate the problem:

1. Try a different USB port on your computer. Check if your thumb drive will be detected.

2. Try a different USB device like mouse on your USB port. If it is detected, it means that the problem is the thumb drive. If not, it means that the USB port is not working or is disabled.

3. Try the thumb drive on a different computer.

Hope this helps. ;-)
