Laptop not recognizing device when plugged into laptop how to fix


The computer is not recognizing the device because the appropriate software or driver is not installed on the device.

Most of the time when you connect a smartphone into a compatible laptop the device drivers or software automatically install, so the laptop may recognize the smartphone.

Here are some possibilities as to why the device is not recognized.

1) The USB port is bad.
2) The USB port is not activated
3) One of the devices does not support the other

Here are a few possible troubleshooting solutions:

1) Go to the smartphone manufactures website and download and install the updated device driver and software then plug in the device to see if it is recognized.
2) (if Windows OS) Go to the Device Manager to see if the device is showing up when it's plugged in. If you see the device in device manager right click the device and choose to update the driver.
3) (if Windows OS) Additionally, in device manager you can check your device's USB ports to see if there is an issue with the ports that may be resulting in the smartphone not being recognized. You can choose to re-enable the USB ports or update the software for the USB ports.

Hopes that helps resolve your issues.

My Acer One AOA150 was restored to factory specs. Crytal Eye webcam will not work now even after reinistalling drivers. Are ther any fixes for this.


I have been through this scenario with four different clients (I have one of these machines, but have not had the problem as yet...using XP) and all have been running Win7 Starter. The camera suddenly disappears from the hardware profile completely. Suggestions to "uninstall/reinstall" and update the driver for what should be showing as an unrecognized USB device won't work, because it simply doesn't show up at all. BIOS fixes, chipset driver fixes, and restoring the OS have not worked, and Acer support has been singularly unhelpful...even resistant to admitting there is an issue (there are literally hunderds of postings of similar problems). Sorry for the bad news of this response, but that's how it is. My most recent client just bought a USB clip-on camera and at least now they have capability. Best regards.

I have a diamond mp3 hooked up to me laptop but windows media does not detect it. What do I need?


Unrecognized devices often mean hat the drivers are not installed or available in Window. Try installing them if you have a CD.
There are more possible problems with unrecognized USB devices, so I suggest you have a look here if the drivers don't solve the issue.

Hi,
Slide the USB connector out and insert it into your computer USB port (any port). Your computer should launch a program for you to install the drive.
You can browse "my computer" or "windows explorer" to see the drive.
Hope this helps...
Very usefull tool!

When i plug things into my usb ports the computer either doesn't register them or it says that it doesn't know what is being plugged in


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

Since you have these many problems with your laptop, Firstly try to reformat the system and reinstall all the neccessary drivers. Many times reformatting works well as your OS might malfunction when you have virus or malwares in your laptop.

OTHER SOLUTIONS
a. for USB:
  1. Click Start, click Run, type Devmgmt.msc, and then click OK. The Device Manager window opens.
  2. Expand Universal Serial Bus controllers.
  3. Right-click a USB Root Hub in the list, and then click Properties. The USB Root Hub Properties dialog box is displayed.
  4. Click the Power Management tab.
  5. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.
  6. Repeat steps 3 through 6 for each USB Root Hub in the list.
  7. On the Action menu, click Scan for hardware changes.

    Windows XP recognizes the new device.
  8. Close the Device Manager window.
b. SD CARD
Your 1GB kingston card might have virus. use a card reader and reformat the card for future use.

c. Uninstall and reinstall the driver of your finger scanner.


Hope this helps,
