First step to try is static discharge.

Disconnect everything from the PC and unplug it from the mains. Press power button and hold it for 20 seconds.
Then connect PC and try if USB ports work


Go to start->control panel->system->hardware->device manager. Expand Universal Serial Bus controllers. Right click on every USB root hub and select uninstall option. They will be reinstalled on next restart.
After that plug USB pen drive to usb port - go to start->control panel->system->hardware->device manager. Click Universal Serial Bus controllers then click on Action tab (the one at the top of Device manager window and select scan for hardware changes.
If that will not solve the issue try different USB port.
Make sure you have latest service pack installed so Windows would install proper drivers for the device.

If that will not work. Restart PC and keep presing F2 key. In the bios navigate to exit menu and select restore defaults. When defaults reset navigate to save changes and exit.

Let me know if this is not solved

SOURCE: My USB ports no longer detect devices when plugged in.

Updating, or in some cases reinstalling, the drivers for your computer's USB interface should resolve this issue.
Locate the iPod in Device Manager

  1. Connect iPod to the computer.
  2. Quit iTunes if it launches.
  3. On the Start menu, click Control Panel.
  4. In Control Panel, open Administrative Tools. Note: If you don't see Administrative Tools, look at the left column in Control Panel for a link that says, "Switch to Classic View," and click it.
  5. Double click the Computer Management shortcut.
  6. In the left column, click on Device Manager.
  7. In the right column, click the plus (+) icon next to Universal Serial Bus controllers to expand this selection.
  8. Locate the iPod in this list. In some cases one of the entries will have "iPod" in its name. If no such entries are present, the iPod is most likely represented by "USB Mass Storage Device."
  9. Note: A red "X" appearing next to the iPod's entry in Device Manager indicates this device is disabled. To enable this device, right-click its entry in Device Manager and choose Enable from the shortcut menu.
  10. Update the USB driver
    1. Right-click the iPod's entry in Device Manager and choose Update Driver from the shortcut menu.
    2. In the Hardware Update Wizard that appears, select "Yes, this time only" to allow Windows to connect to the Windows Update Website. Click Next.
    3. Select "Install the software automatically (Recommended)" and click Next. Windows searches for updated drivers and installs any it finds. If Windows is unable to find updated drivers on its own, continue with step #4.
    4. Click Back.
    5. Select "Install from a list or specific location (Advanced)" and click Next.
    6. Select "Search for the best driver in these locations."
    7. Select "Include this location in the search" and type the following in the field below: C:\Windows\INF
  11. Click Next. Windows searches this location for drivers and installs any it finds. If Windows is unable to find updated drivers on its own, you must reinstall the USB drivers as shown below.
  12. Note: During installation, if a message appears stating that the software you are installing "has not passed Windows Logo testing" click Continue Anyway to continue installing the drivers.
  13. Reinstall USB driver
    1. Right-click the iPod's entry in Device Manager and choose Uninstall from the shortcut menu.
    2. In the resulting dialog box, click OK.
    3. In the Device Manager window, right-click Universal Serial Bus controllers and choose Scan for hardware changes from the shortcut menu.
    4. Windows automatically reinstalls the necessary USB drivers and attempt to remount the iPod. Regards...

I tray to changing 3 new keyboards but still reads the problem. What's your problem?


OK what type of keyboard are you using Serial or USB? A serial type keyboard has a round end that plugs into the computer's PURPLE port (the Green Port is for the mouse).

A USB type keyboard has a flat end that plugs into one of the computer's usb ports.

If you are using a Serial (Round end) type keyboard, it is not Plug and Play (meaning you cannot unplug it or plug it in while the computer is running or it will not be recognized). You can only plug or unplug the serial keyboard when the computer is off. If you turn the computer off and plug it in good then reboot and you still have a problem then since you have tried 3 different keyboards, maybe the Purple Serial Port where the keyboard plugs into the computer is bad. Try a USB Type Keyboard.

A USB (Flat end) keyboard is Plug and Play. You can unplug and plug it while the computer is on. Also you have the luxury of plugging it into any one of the computer's usb ports.

When i plug my 4g cruzer micro usb memory stick nothing happens the cpmuter dosnt read that it is plugged in


Try a different USB device on each of the USB ports on your computer.
Hopefully, all your USB ports are working correctly.

Try a different USB port on your computer.
Hopefully, the SanDisk will be detected on one of the ports.

Try a USB port on a different computer.
If the SanDisk still is not detected, then spend $10 to buy a new 4GB flash-drive.

HP Pavilion zv6000: USB ports are inop. USB port on rear of computer works fine. USB port on left/front will power my flash drive, but the light stays on constantly. The flash drive is does NOT show up in...


After reading the description, I think you need to try updating BIOS and latest device drivers for USB. Because USB are getting power on that means there would not be any fault to from the motherboard.

So please try updating latest BIOS for your notebook.
If you can provide me the product no for your notebook and the operating system which you are using currently then I can find the one for you.

Otherwise you can also do the same.

Type in the product no. on www.hp.com. Then go to software and driver download page, select the proper OS and search in BIOS ROM pack available for your notebook.

I hope this will help.

I added a 512mb stick to my ibm t30 think pad and one port is bad


You can plug a USB hub into the working USB port on the computer. The USB hub can have several ports so you can plug in several USB devices.
I suggest you get a powered USB hub because if all the devices that you plug into this hub exceeds 500mA then your computer's USB port will stop working because it could not supply enough current.
You will not need to plug in the power adapter into the hub if the device/s do not overload the computer's USB port.

HELP ME PLEASE!!


I'm not sure which Coby I have but my computer wouldn't read it when I plugged it into the USB port. What worked for me was to take out the battery, plug it into the USB port, add a couple of mp3 songs, unplug it and plug it back in. It was recognized with all the existing media on it and I could edit and delete. Hopefully you have room to add an mp3 or two. My solution last time it happened was to reformat and reload.

Usb ports


You'll want to verify your computer recognizes your usb ports.
In device manager, look to see that you don't have anything with an exclamation mark, question mark, or red X on it. Make sure you have the usb ports listed under Universal Serial Bus controllers. If nothing shows, your usb ports may be dead. Depends on the age of your computer and what might have happened to them.

Device manager- right-click My Computer and go to properties, then select the hardware tab.
