Try deleting the USB controller in the system properties and rebooting. The system should reinitialize the hardware and reinstall the drivers, which should take place automatically.

HD-PNT1.0U3R-EU driver


Possibly an issue with your PC's USB ports as well. Plug something else into that specific port to see if it will work. If not, then it's an issue with the motherboard.

For drivers, contact Buffalo.

Usb ports not recognized


Did this suddenly start to occur? Were they working before? If so, it is very simple - shut down computer, remove the battery and unplug any power source, wait a couple of minutes and reassemble and power up. Wala! I read all kinds of complicated instructions, started with the simple, and problem solved.

Simpletech 500 GB external hard drive - unresponsive


If you really can not get it to work anymore, you could try opening it up and connecting the hdd directly on a IDE/SATA port in your computer. This will only work if you have a desktop, for a laptop you would need all kinds of converters.

USB Ports on AL27 only work with printer and external hard drive.


I fixed the problem by going to "Device Manager," then to the "Universal Bus". Under "Universal Bus" are a list of the individual USB ports. You have to delete each one individually. When you delete each one, a window opens up which gives you various headers; select "drivers" and hit "uninstall". When you hit "uninstall", windows will ask if you want to proceed. Select "Yes". You'll then get a "warning" that the computer may not work correctly if do this procedure. You want to proceed with the deletion of each Universal Bus port. Once you've removed the Universal Bus ports, then reboot windows. Windows will detect the individual Bus ports and find new drivers for them. Once the drivers are installed (automatically by Windows), the USB ports will be operational.

try one of the method below:
Method 1: Try different ports loadTOCNode(2, 'moreinformation'); Warning If you have to change a PS/2 connection, shut off the computer, make the changes, and then restart the computer. Do not plug a PS/2 device in the PS/2 port while the computer is running.

To determine whether the problem is related to the ports on the computer, use only the two cables that are included with the wireless desktop receiver, or the single cable that is included with a mouse.
USB keyboard and USB mouse loadTOCNode(3, 'moreinformation'); If the USB cable is currently connected to a USB hub, disconnect the device from the hub, and then connect it to a USB port on the computer. If your device is already connected to a USB port on the computer, try to connect the device to a different USB port if one is available.

Note Only one USB connection to the computer is required, even if your device has two USB plugs. If the problem persists, disconnect other USB devices and connect only the USB plug from the receiver to a USB port on the computer.
PS/2 devices loadTOCNode(3, 'moreinformation'); If your devices are connected to PS/2 ports on the computer, verify that you have the following configurations: • Verify that the USB plug for your mouse is connected to the green USB-to-PS/2 adapter and that this adapter is plugged in the mouse PS/2 port on the computer. The mouse PS/2 port on the computer may also be green. If you are not sure which PS/2 port is the mouse PS/2 port, see the documentation that came with the computer. • Verify that the USB plug for the keyboard is connected to the purple USB-to-PS/2 adapter and that this adapter is plugged in the keyboard PS/2 port on the computer. The keyboard PS/2 port on the computer may also be purple. If you are not sure which PS/2 port is the keyboard PS/2 port, see the documentation that came with the computer.If you have to change your configuration, shut off the computer, make the changes, and then restart the computer. If your mouse or keyboard has both USB and PS/2 connections, try using the other connection.
PS/2 keyboard and USB mouse loadTOCNode(3, 'moreinformation'); Verify that the USB mouse is plugged in a USB port on the computer and that the purple keyboard PS/2 plug is connected to the purple PS/2 port on the computer. If you have to change the PS/2 connection, shut off the computer, make the changes, and then restart the computer.

Method 2: Install fresh batteries loadTOCNode(2, 'moreinformation'); Both the wireless keyboard and the wireless mouse rely on AA alkaline batteries for power. If the problem persists, install a fresh set of batteries in the device that you are experiencing problems with.

Method 3: Resynchronize your device to the receiver loadTOCNode(2, 'moreinformation'); To resynchronize the mouse or keyboard to the receiver, follow these steps.

Note When you synchronize the mouse or the keyboard with the receiver, put the device near the receiver and put other wireless keyboards and mouse more than six feet away. 1. Press the button on the receiver, and then verify that the light on the receiver starts to blink. 2. If a dialog box appears on the screen in several seconds, follow the instructions that appear on the screen.

Otherwise, go to the next step. 3. Press and release the Connect Channel button on the bottom of your mouse or keyboard. 4. Check the green light on the receiver. A steady green light means the synchronization was successful. If the problem persists, try steps 1 through 4 again.

Method 4: Install the latest software loadTOCNode(2, 'moreinformation'); If you are troubleshooting a wireless mouse, download and install the latest Microsoft IntelliPoint software. For more information about IntelliPoint software, visit the following Microsoft Web site:
http://www.microsoft.com/hardware/mouseandkeyboard/Download.mspx (http://www.microsoft.com/hardware/mouseandkeyboard/Download.mspx) If you are troubleshooting a wireless keyboard, download and install the latest Microsoft IntelliType software.

Method 5: Clean the mouse lens loadTOCNode(2, 'moreinformation'); This problem may occur if you are using an optical or laser mouse and the lens on the mouse is dirty. To clean the lens of an optical or laser mouse, follow these steps: 1. Use a dry cloth to clean the bottom surface of the mouse. 2. Check to see whether the mouse functions correctly. 3. If you see dust on the bottom of the mouse, use a can of pressurized de-ionized air to blow away the dust on the lens. 4. Check to see whether the mouse functions correctly. 5. If the pressurized air canister is not available, blow dry air on the lenses by using your mouth one or two times. 6. Check to see whether the mouse functions correctly. 7. If these steps do not resolve the problem, use a cotton bud to clean the lens without scratching it.

2 0f 4 ports do not work


It sounds as though the ports on the cable/dsl router as bad. There really isn't anything you can do. It just happens. The typical shelf life of those routers is about 3-4 years. You could go out and buy another one or if you just need more ports go out and buy a little 5 port switch and plug it into one of the working ports and your comptuers into the 5 port switch.

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.
