Check out the Device manager: for which USB device its showing error, it will be flagged or question marked.

If you have all the devices attached to PC installed properly then this error will not come again.

Remove all the devices to check it out and let me know. So I can investigate further.

My computer has stopped recognising the driver for a 500gb Lacie Premier Multimedia Hard disk. It appears as 'Unknown device". how do i locate and replace the driver.


Most USB accessories do not get recognized well when plugged in before startin the computer. The exception seems to be mice. USB hadr drives and flash drives specially seem to have this problem. I always use the disconnect icon in the system tray to disconnect before shutdown and plug them in after windows has stabilized. I even gets worse if you use a USB hub. Some devices will not be recognized when attached to a hub.

MY PROBLEM IS THAT IF I USE ANY USB DEVICE THERE IS A MASSEGE COME THAT ONE OF THE USB DEVICES ATTACHED TO THIS COMPUTER HAS MALFUNCTIONED AND WINDOWS DOES NOT RECOGNIZE IT. HOW CAN I SOLVE THIS...


Hi!
It appears your Usb drivers maybe corrupt, have you tried going into device manager and removing/re-installing them.
I trust you have the operating system disc? if not set a restore point and back up your files etc., first!
Good Luck!

My 160GB Crossfire is not recognised when connected to any of the USB ports. It used to be, but then I've had some other PC issues recently that meant a forced closure of the PC and I'm concerned that...


When starting the external drive there is not much more than just plugging it in to a USB port and turning it on. The computer should recognize it ( showing something like the window shown here http://attachments.techguy.org/attachments/66120d1129787805/new-device-found2.jpg ) and it will show up in the My Computer area and a green arrow looking icon ( http://home.krb.nsw.edu.au/start/images/USB2.jpg ) When disconnecting an external drive the correct procedure is to left click the arrow in the system tray and select Safely Remove Mass Storage Device (X:) (whatever letter you device shows here)
You may want to test if another computer recognizes the device being plugged in to see if it is still functioning. You may want to also try plugging the device into a different USB port on your computer.

I plugged my Memorex TravelDrive into my computer. It has always worked perfectly. This time I got the message that the USB device was not recognized and I can't get into my files.


THE FOLLOWING IS COURTESY OF MICROSOFT Help and Support

When you plug a USB device into a Windows XP-based computer immediately after the computer comes out of standby (S3) or hibernate (S4), the computer may not recognize the USB device. When this issue occurs, the USB device may be listed in Device Manager as an unknown device, and you may receive the following warning message:
Unrecognized device has been found.

This issue occurs because, when the computer comes out of S3 or S4, there is a five- to ten-second period when the selective suspend feature of the USB driver will interfere with detection of a new USB device connection. The time period depends on several factors. This includes the following factors:• Host controller hardware
• Attached hubs
• Attached devices
• USB driver versions
• Support for USB 2.0
• Additional system hardware or configurations that may change the timing
There may be other reasons that a USB device is not detected

Method 1
loadTOCNode(2, 'workaround'); After the computer comes out of S3 or S4, wait five to ten seconds before you plug the USB device into the computer or hub.

Method 2
After the computer comes out of S3 or S4, unplug the USB device, and then plug the device back into the computer or hub.

Method 3
Use the Device Manager to scan for new hardware. Follow these steps: 1. Click Start, click Run, type Devmgmt.msc, and then click OK..
2. On the Action menu, click Scan for hardware changes. This causes Windows to recognize new devices.
3. Close Device Manager and Control Panel.

Method 4
Disable power management of the USB hub.
Note If you perform the following procedure, you may also reduce the battery life on a portable computer.
To disable power management on the USB hub, follow these steps: 1. Click Start, click Run, type devmgmt.msc, and then click OK.
2. Expand the Universal Serial Bus controllers node, and then follow these steps for each USB Root Hub that is listed: a. Right-click the USB Root Hub, and then click Properties.
b. Click the Power Management tab.
c. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.

Try restarting the computer with the device in. Sometimes if you clear the memory that might help (stating the machine without memory then put it back and start it again).
