USB Ports don't recognize typical thumb drive, mass storage devices

Since I purchased the computer in 5/08 the USB ports often don't recognize typical thumb drives. Occasionally it works fine but more often I get an error message that the device is not recognized. I have tried different brands of different size thumb drives, but when the computer is not in a "mood" to recognize them it just doesn't. Any advice? Thank you!

    Thank you for the quick response. These thumb drives have never needed drivers before and do not come with drivers for my previous, older computers. I am using ZT 5014ZI-33, with Vista Home.

    I've got the same?
    I've got 2 external HD that are not recognized by XP on my desktop but they are on my laptop (XP).
    I tried to change driver, I've formated computer, usb in BIOS ok,....
    Strangly, when I use a usb1 hub, it works!!!!
    So if someone has the answer I would be interested in fast working.

I'm not completely sure, but this may be a result of faulty drivers.
Try googling the brand name and the word: "Driver"; along with any other details about the device. (Model No. et cetera.)

    I'm sorry, I should have been more specific;

    I meant details about your thumbrive/USB device.



    Tell me the details in a comment and I'll be happy to find the drivers for you.

Where is the USB root hub on a Gateway PC so I can plug in my mass storage device


You don't plug a device into a root hub. The root hub is the central detribution point for all the USB ports on your computer. Your storage device should plug into any available USB port. If you are talking about an internal port then it is possible that you dont have one or may have to attach wires to make a port usable. Take it to your local computer guru and he/she should be able to help you for little or no cost.

Failure to recognize CD ROM or USB ports


  1. Run Registry Editor (regedit).
  2. Navigate to the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\UsbStor
  3. In the right pane, double click on the Start value name.
  4. Change the value data to 4 to disable the removable USB mass storage device drive access
  5. 5.
  6. To revert and re-enable the drive access for removable USB mass storage device driver, change back the value data for Start to its original default of 3.
The change will take effect immediately to block any USB mass storage device such as USB flash drive, USB key and portable harddisk from been used in the system, while still allowing hardware components to work properly via USB connection. The hack works in most Windows operating system such as Windows Vista, XP, Windows Server 2008, 2003 and 2000.
For user who dare not to modify the registry manually, simply download the following registration entries file to enable or disable the USB drive. Extract the downloaded content in .ZIP format, and then double click on the .REG file to open and apply or merge the registry values to system.

Greetings....

Please try to check if your USB port both rear and front USB port are not defective. Most common problem of defective usb ports are when plug your usb devices it won't recognize the device you inserted. So to make sure that your USB Ports are not the main cause why your computer won't recognize devices you inserted.

Usb not recognizing device t2882


Hi,
What I suspect here is that,
Provided the operating system that you are using is Up to Date (e.g WinXP SP2 to Win Vista),

the USB port that you are using might be a USB 1.0 port, which has a lower voltage not enough to power on your Storage drive.

In this case, there are two things you can do,

1. Change the USB port you are using for the storage drive to a USB 2.0 one (Just keep Checking all the ports one by one in case you dont know which one it is).

2. If your Storage drive has external power facility, just plug it in an external power first, before connecting it to the system.

If there are no USB 2.0 Ports on your system at all,

then just go to any electronic store and tell them you want to buy a USB 2.0 Expansion card.

and if it is a laptop, A USB 2.0 PCMCIA card.

Install it on your system, and connect your external drive through it.

Hope this helps you out.

Goodluck

USB suddenly malfunctioning on Dell TOwer


It does sound like your ports on the front might be bad. They usually connect to a seperate port on the motherboard than the rear ones, and I have seen devices short out the front ports, such as a USB music player.

You can remove the ports on the device manager, and they should come back ok, without worry. However, I doubt that is going to help the front ones. I think you have a hardware problem.

If that is the case, the easiest solution is to get a USB hub, and run a USB cable from the rear, to the front of the computer.

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.

Need instructions for eGo portable hard drive. This shold ave come wit th purchase but did not.


there's no much need for instructions.
you just plug the hd into a USB port avaliable in your computer. the operating system should be able to recognize it a few seconds after you have plugged the hd into the usb port.

some hd may require for 2 usb to be connected to the computer for the computer to see it.. usually they come with a "y" usb cord. one goes to the hd and 2 usb type a cord go to 2 usb ports on the computer

to check to make sure the computer sees the hd. go into my computer and check if a removable storage device has appear.

also check your hd is on, some external hd may have switch to turn them on.
also check if your hd requires external power if it does it should come with a power connector that needs to be connected and plugged into the power outlet for it to work.

post your finding if you need more 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,
