Question about PC Desktops

3 Answers

My computer does not always recognize that I have My Book connected when indeed it does. I have the USB cable in the proper port. Sometimes when it does show it is connected I still can't get to the data on my external drive. It says it isn't there. Also, I did not receive a user manuel in with the purchase of my WD 320.

"Not always" means that it does work sometimes. If so, look to cable or connection.

First, please disconnect all USB devices and then perform the following steps:
Click "Start" button, type "devmgmt.msc" (without quotation marks) in the "Search" bar and press "Enter". Click "Continue" if necessary.
In Device Manager, double click to expand "Universal Serial Bus controllers", right click on the Host Controller, click "Uninstall" and click "OK".
Repeat the step 2 to uninstall all items under "Universal Serial Bus controllers".

Then, restart your computer and Windows 7 will reinstall all USB controllers automatically.
for XP or earlier

you will need to update/reinstall drivers right click to reinstall drivers
if you can see your usb drive but its not working
ports (com&lpt) right click update driver if this fails to fix the problem
Check the USB leads that attach to the motherboard usually red white green black make sure they are securely seated and have no dust build up on them dust will cause static and a lot of unforeseen problems to a computer and its parts Check if USB Ports Are Damaged

USB ports are an important part of your computer's hardware.
Many devices connect to the computer via USB, such as music players, cell phones and digital cameras.
This connection lets you charge your devices and manage files on them.
When you connect a device to a USB port, it is typically recognized automatically.
If not, there may be a problem with the port. USB ports sometimes fail on their own, or they may be damaged by force.

Plug a variety of devices into the USB port you think is damaged.
If none of them work, the port is probably broken.
Connect the same devices to the USB ports on a different computer.
If they work, this is another indication your ports may be damaged.
Run Windows Update on your computer to ensure your devices and computer function together and have the latest drivers.
Click "Start," then type "Update" in the search bar.
Click on "Windows Update," "Check for Updates" and "Install Updates."

Open the Windows Device Manager by clicking "Start," then typing "device manager" into the search bar.
Click the Device Manager link when it appears.
Click on each of your USB ports.
In the Properties window, look for "This device is working properly."
If this is displayed for each USB port, they are not damaged, but there may be a problem with your device instead.
Click "Update Driver" next to each USB port in the Device Manager, and Windows searches for and installs the latest driver.
If one can't be found, go to your computer manufacturer's website, and download the driver there. Try to use the USB port again.
Sometimes, outdated or damaged drivers result in a non-working USB port.

Open your computer case by unscrewing or sliding off the side cover.
Use a can of compressed air to clean out the dust from inside, especially from within the USB ports.
If your USB ports are hooked up to the motherboard, remove the cable, then replace it.
These actions sometimes help to fix non-working ports.

How To Refresh and reinstall USB Ports Of Your Computer Hello there, the other day i tried refreshing and reinstalling the USB ports on my PC, as some of my connecting devices are not recognized. I present the detailed procedure on refreshing the USB ports.
Let’s go!!

Here are the steps to refresh/reinstall/uninstalling the USB ports on the computer.

The USB port needs to be refreshed to make sure that no other device has captured the USB port of the computer. The Mouse, video camera, your external USB hard disk; what ever it may be.

Follow the steps given below to refresh USB ports.

1. Right-click My Computer icon on the desktop, and then select Properties.
2. Click the Hardware tab.
3. Click the Device Manager Button.
4. Click the plus (+) sign to the left of Universal Serial Bus controllers.
5. Right-click the device listed under Universal Serial Bus controller and select Uninstall.
6. Click OK to confirm the removal of the device.

Please note, repeat Steps 5 and 6 until all the devices under Universal Serial Bus Controller are removed.

7. Shut down the computer.

CAUTION: Ensure that the Shut Down option is selected, instead of the Restart option.

8. Wait for 5 seconds and then restart the computer. When the computer restarts, a "Windows has detected new or added hardware" message window will open.

The above steps will refresh the USB ports.

Now connect the USB devices like mouse, video camera, your external USB hard disk...USB hubs...whatever you like and the drivers should install automatically.

Tip: It is always recommended to connect the main USB devices at the rear end USB port. As they require more power to initiate.


The above steps are for XP operating system. When coming to the matter of Vista, please note the changes below:
===========================
1) Right-click Computer icon from the desktop , and then click Properties to open the System Properties window, and then select the Device Manager tab.

2) Click the Plus (+) sign next to Universal Serial Bus Controllers/Root hub.

3) Click the USB Composite Device entry to highlight it, and then click Remove. If a screen appears to confirm the deletion, confirm the deletion.

4) Disconnect the USB cable to the all-in-one, wait a couple seconds, and then reconnect the cable. This should restart Windows device detection (Plug and Play).

5) A New Hardware found screen may appear, click next through all of the screens that appear for the Wizard to install the USB Composite Device. Click Finish once the wizard completes.

New Dell desktop can't recognize external hard drive


I devised these simple steps that tend to remedy quite a few issues with most USB portable / external hard drives and devices (though not always)

A few things to check but assumes USB and Windows for other interfaces / operating systems similar steps may be adapted to suit.

1. Ensure it is connected directly to the computer to a USB 2.0 port not a USB 1.0 port as this can have effects on performance and reliability

2. Use only the cables that came with it NOT one that fits that may have been lying around or is longer. Not all USB cables are equal even though they should be)

3. Do not connect through an external USB HUB unless that hub is USB 2.0 AND has its own power supply.

4. Use ONLY the power supply that came with it if it has an external power supply Don’t use any other unless you know it has both the same voltage and current rating e.g. 12V 500mA anything rated below that would not work properly.

5. Always use the same port for connecting your devices. Some devices do not like being switched about. If switched they may want to install software / drivers again. This can be especialy true if you move a HUB to another port

If you checked and fixed anything there and still have issues then check your hardware from CONTROL PANEL / SYSTEM / HARDWARE.
Any exclamation marks by hardware need fixing before you investigate any further

My 2 usb ports on my monitor not working


In order for the two USB ports on the monitor to work, the monitor itself has to be connected to your computer via another USB cable with connectors that look like this:
8130925.jpg
The flat connector goes into an available USB port on your computer, the square one plugs into your monitor. Check if your cable is connected properly or exchange it with another one.
To eliminate that there is something wrong with your "not recognized device", plug this device into another USB port of your computer. The reason to preferably remove the device safely in Windows is that you can loose data if you just unplug it. If it is an external harddrive, it can get damaged, because you interrupt the power and the read/write head can get "stuck". So check this device on another computer or USB port.

If you have any other questions or something is not clear to you, just come back here and leave a comment and I'm happy to help.

Maxtor one touch 4 mini- not connected! The single USB cable is in the Computer USB port.So far so good. When the second USB connector-with 2 cables is inserted to another Computer’s USB Port I start...


Quite strange.. I would suggest that maybe one of the usb ports is faulty.. Or ofcourse, one of the cables.. Or the usb port has been mis-wired inside the pc. That has been done before. Anyway, do you have access to 2 usb drives.. I mean micro/thumb drives? I'd test each port by itself first, to see if they operate correctly, then if they do, use the two usb drives in the two usb ports at the same time, to test read & write.. I guess there are other things you could try, like going to control panel, system, hardware, device manager & checking on the status of the usb ports. That may tell you something worthwhile. Whatever you do, test each port with the one single cable. Yer, this is a strange fault. Let me know how you go. Rgds,

USB Non-responsive


Perhaps its the drivers for the USB ports. Do you have or can you borrow a serial mouse and keyboard (PS/2 style)? If not, perhaps a local computer store may have an adapter to convert your USB devices to PS/2. Look at this site to get a visual of the device I am talking about: http://sewelldirect.com/ps2tousb.asp

This will allow you to bypass the USB portion of your computer and allow you to make the necessary changes in BIOS or to see if it is indeed a driver problem.

It's either the USB port, the drive electronics itself, or the USB cable.

First I'd try a different USB cable.
