Solve : All USB ports stopped working!!? |
|
Answer» I have a Sony Vaio, older computer, operating Windows XP, After utilizing a borrowed flash drive the other day all USB ports stopped working, those on the front and rear. I have usually connect printer, camera, ipod, etc. When attempting, there is no response. I uninstalled all usb connections and rebooted, however all external connections do not work. Is this problem fixable, any ideas??? When reinstalling I used printer disc and it says all drivers are ALREADY installed. 1. Let's try a hardware reset of the USB circuit. The theory is if you remove "all" power from the circuit, it should then recognize power on and perform hardware reset of its circuit (and firmware?) to an initialized state (Hey, I read this in a blog once. It's simple, easy, and worth a shot). I did as you said with no luck. It did not recognize my printer, or Ipod. Any other suggestions? I've considered wiping system out and starting over however I have 3 years of pictures of my kids saved on the computer and don't want to loose them. I am grateful for any help or suggestions you may have to offer. Thanks in advance.NO! Don't wipre that HDD! Do you have an empty PCI slot? http://www.amazon.com/Port-Pci-USB-2-0-Card/dp/B0002M4HU0 About $14 plus tax and shipping. I don't think I have a PCI slot but not sure exactly what PCI slot is! There is a DVD-RW slot, a CD-Rom slot, and a 3.5 disc drive. There are no other slots. Google pci slotSorry. I thought it was a desktop. The Sony laptop has known problems with the USB ports. I am not ABLE to advise you on this. But I think it means you have to update the drivers. At some point a Windows update may have made the USB ports unusable until you get the new drivers. Sorry, I am not sure of this. Maybe somebody else here knows about the Sony problems with USB.It is a desktop, and I do have 3 pci slots. (Now that I know what they are). Would you recommend purchasing the product you gave link to and hooking it up. Will the other usb ports ever be usable?OK. Back on same page. I was afraid you had a laptop. With the desktop you can just stick in the card in a normal PCI slot and you have new USB ports on the back of the card. The original other ports are not changed. The original USB ports will remain dead, unstable or whatever. The card will come with a install CD if needed.You could plug a known good USB flash drive into a USB port, and then boot to a Live CD containing an operating system that automatically mounts and recognizes USB flash drives. If it recognizes the flash drive, reads the flash drive, and correctly displays its directories and files; you know the USB hardware circuit and that port is "working". This would suggest the problem lies within the current operating system on your hard drive. The known good USB flash drive should be formatted with a file system the alternate operating system will recognize; e.g. FAT32. Two Live CDs which I've just tested this on are: a. Ubuntu Desktop 9.10 (32-bit) b. Hiren's BootCD 10.1 |
