USB ISSUE

[CarterWindows7]

Hello Everyone.

I have just come on to my laptop and i have found 'USB Not Recognized' And i have code 43. I have used all usb ports to check, and it still doesn't work? It worked perfectly fine yesterday. It is a web-cam.


P.S My laptop is acer, And i dont no an awful lot. But i really need help! What do i do?

can you connect any other device via usb such as external keyboard or mobile phones or joystick???

Code 43: Windows has stopped this device because it has reported problems

The first thing to try is re-installing the USB controller drivers.

If that does not work then it is most likely that your hardware has failed.

ace, my mobile phone usb works and connects fine its just the webcam? and how do i reinstall usb controller drivers? im so shit with laptops!

Well, you can also try re-installing the web-cam drivers.

To install drivers, go to "Device Manager" in your Control Panel, click on "Universal Serial Bus Controllers"



Right click on the device to which your webcam is attached, and then on "Update Driver Software".

Don't worry about all the USB stuff you see in that image, I use a lot of USB stuff so I have a lot of hubs. You might only have one!

you have to reinstall your chipset driver which you will get here Acer Europe - Service & Support, Drivers & Utilities, Downloads
select your lappy model and then download from there and install

If it is an "Unknown Device", that means Windows can not recognise it.

Unplug the webcam. Try plugging it into another USB port. If that does not work, and you do not get a message from Windows, then the webcam is most probably defective.

Have you tried rebooting the system?

Did this happen after the computer was in Sleep mode?

 

[CarterWindows7]

Yes shootist.

My Laptop is a Acer 5532, Windows 7. Ive re-booted, and tried to reinstall but it stills say 'USB NOT RECOGNIZED'? What shall i do..

Provided it's not a hardware issue (like broken cable, defective plug or even a defective USB on your motherboard etc)
You got to go through a process of elimination:
Take a hard look on what you've installed/updated/done since the cam worked last time.
Try the cam on a different computer to exclude it as the source, plug in some other USB device to see if the usb ports of the laptop are working OK
To exclude any recent software changes I would use a restore point from the time when the cam still worked. (if that doesn't help you could always revert this because Windows creates a new restore point before it uses a previously made one)

Good Luck
