The reason for your computer not recognizing your USB cord can be many. The first most possible one is that your USB port has stopped working and you can't do any thing about it, it must be due to the fact you are using an old computer and the USB port has malfunctioned.

The second reason for the USB not being recognized is from malfunctioning of USB cord or the device connected, for instance a malfunctioned USB flash drive is also unable to be recognized.

The third reason which is mostly found if the devices are working perfectly is because some times the BIOS of your computer has changed its setting automatically and turned off the capability of any new hardware being recognized. Therefore a simple way to solve this problem to reset BIOS. However care must be taken in this respect since you should refer to an expert before changing any settings as any wrong settings can lead to permanent damage.

If the changing or resetting of BIOS settings doesn't help, then it probably must be the Operating system that is installed, for this you can try reinstalling your OS as a last resource.

However if all the above reasons and solutions are still unable to solve your problem, it probably must be a more unique problem and you should council the vendor of your computer for more information.

My computer suddenly did not recognise the usb my printer had been in for ages.After trying another usb port on the rear of the computer;it still didn't work!But when I tried it in a usb port in the front of computer IT WORKED STRAIGHT AWAY!(Presumably two ports next to each other can share a fault.)I wish I'd known this,could have saved hours.MICK.

I had the same problem. I was so aggravated! I almost went and bought a different printer from a different company. My advice is to unplug the power supply and the USB cord from the printer itself for a few minutes. Then plug everything back in and then your computer should be able to "recognize" the USB cord. Atleast that is what happened for me. I have a x5470. I hope this helps!!!!!

Some times when we put a device into USB port then computer does no recognize it. Try to put the same device in another USB port and if still it does not work then restart your computer. Actually some times we do not take care about how we are removing a device from USB port.

I mean first we should stop the computer to read that device. You can try yourself, just put your web cam in USB port and remove it directly without stopping the computer to use web cam. Now again put your web cam cord in USB port and again just take out the cord from USB port directly. When the third time you will enter your web cam cord into USB port then computer will not recognize it because you did not properly shutdown the web cam properly. So always properly remove a device from your computer USB port. Some times virus does not allow computers to recognize a device.

It could be possible that your computer registry is corrupt and your computer is not recognizing the device entered into USB port. Some times virus affect on computer settings and if virus has changed the setting of your plug and play devices then it is very much possible that your computer will not recognize any device connected through USB port.
