Having problems with your HP Computer Utilities & Maintenance ?

USB ports don't recognize memory sticks or external harddrive.

\015 This is an HP desktop that has been very reliable for the last couple of years since its last upgrade. All of a sudden, all the USB ports don't recognize any memory sticks or external hard drive, but they work fine on other desktops and laptops. Also, other non-memory type of units I plug into this HP desktop work fine, its just memory type of units that don't work.\015

Answers :

If your using a usb hub or similiar, try connecting directly to the front or the back of your machine.
Do you have another USB cable to try or is the usb connector directly on the USB device?

Try these steps to reinitialize your usb ports on your pc
\015\012
\015\0121. Unplug ALL USB devices connected to the\015\012computer. If you are using a USB mouse and keyboard, temporarily use\015\012the older type PS/2 devices if you have them, if you don't then just\015\012leave them connected.
\015\012
\015\0122. Hold down the windows key and press r
\015\012
\015\0123. Type devmgmt.msc into the run menu and press ok

5. You might need another mouse to do this if you have a usb\015\012mouse.. I recommend you get a ps2 connector mouse which goes into the\015\012green round connector in the back of your pc.

6. Right click and uninstall first the usb root hubs. all of\015\012them then uninstall the rest of the devices you see under Universal\015\012serial bus controllers
\015\012
\015\0127. Ones you have uninstalled everything you should see the Universal serial bus controllers there at all.
\015\012
\015\0128. Now go ahead and restart your pc.
\015\012
\015\0129. Ones you have restarted the pc your usb ports will reinstall\015\012in a moment stand by while it installs all of them. If you get warning\015\012messages click ok or continue installation.
\015\012
\015\01210. Now go ahead and plug the usb devices back in. Install\015\012software if required, all usb devices if not faulty or broken should\015\012work now. Also note the error code if you get one?
\015\012
\015\012This solution doesn't fix all usb problems so if you have a yellow !\015\012mark there and device status reports a error code. Then it might not be\015\012a problem with your usb ports.
