How can i get my computer to recognize my flip?

it says it isnt recognizable and it has been b4.

If your PC isn't reading the FLip when it did before, then I'd check your hardware device manager to see if there's any "!" next to your USB ports. It may be that there's a problem with your USB drivers. If so, remove them and reboot. Windows will re-acquire them and you should be good to go then. Also, scan for spyware and viruses.

FLip also recommends the following:

First, ensure that you are inserting your camcorder into a high-powered USB port, as your Flip Video camcorder needs electrical power in order to run in its connected mode. Some USB ports are low-powered or are not powered at all (e.g. the USB port on a Macintosh keyboard is not powered), so you should try another USB port on your computer if this is the case.

Secondly, ensure that your camcorder is turned OFF before connecting it to your computer. Then, after inserting the camcorder's connector arm into the USB port on your computer, you should hear a small beep from the camcorder as it turns on in its connected mode. You should also see the word "Connected" on the camcorder's display screen when the camcorder is properly connected.

If you do not hear a beep or see "Connected" on the display screen, then your camcorder may be experiencing a problem with that specific USB port on your computer. Try to use a different USB port with your camcorder. If no USB ports on your computer work with the camcorder, ensure that other USB devices work with your computer -- try to connect a different device to your USB ports, such as an iPod or a standard digital camera.

If other devices work with your USB ports, but your camcorder still does not work, you may be experiencing a problem with the USB connector arm on your camcorder. If this is the case, please contact Flip Video Support at http://support.theflip.com.

The last one happened to me once and Flip replaced it under warranty.
