I just bought a new Gateway NV53 laptop but my P4350 Lexmark all in one printer does not recognize any of the USB ports.


Did you check whether the USB ports are recognizing other USB devices such as Microvault or Flash Drive? If all other USB devices are recognized except the Printer, then reinstall the USB Drivers. You can uninstall the USB drivers from the Device Manager and restart the Computer. The USB Devices are listed under Universal Serial Bus Controllers in the Device Manager.

Not able recognize the usb device for windows 7


If you can, check that the printer is still recognized on another pc. It's possible that the printer is faulty.
If it does work on another pc, then the next step is to try a different USB port on your computer, preferabbly one at the back of the computer, not the front.
Also make sure you have install the drivers before you connect it to your computer.

USB not recognized during printing and scanning


Some motherboard or operating systems have problems if you leave usb devices plugged in. They don't recognize that the device is still there and ignore it. These are referred to as "Legacy USB devices". There are a couple of things to try.

Make sure the problem isn't the printer if you can. If you have another computer just plug it in long enough to for the operating system to recognize something has been plugged in.

On this computer giving you the problem. unplug the usb cable and insert into a different USB port. Usually this is enough to "fix" it and make it usable.

Next is to unplug the usb and reboot the computer a few times. Then insert into a different usb port.

Past this point if it still isn't working then you need to go to control panel-system-hardware manager-usb devices and delete all entries under the usb header. Then reboot. This forces the operating system to find all the usb ports and reinstalls the drivers. Then plug in the usb and it should work again.

USB device not recognized


Hello,
SOLUTIONS:
  1. Unplug the USB device. It is possible that the connection is not secure and has become loose. This is one of the most common reasons for an error in detecting a USB device.
  2. Use the Device Manager to scan for new and recently installed hardware. From the start menu, select the 'Run' option. In the pop up box, type in Devmgmt.msc and then click 'Ok'. From the 'Action' Mmnu, click 'scan for hardware changes'. This will make Windows recognize any new devices that are installed. Now, close all device managers and control panels. Now see if your computer will read the USB device.
If the above two doesnt work, then try the following,

Disable power management of the USB hub. To disable the power management,

1.Click Start, and then click Run
2.Type devmgmt.msc in the Open box, and then click OK.
3.Expand the Universal Serial Bus controllers' node, and then follow these steps for each USB Root Hub that is listed:
4.Right-click the USB Root Hub and then click Properties.
5. Click the Power Management tab.
6. Click to clear the Allow the computer to turn off this device to save power check box, and then click OK.

PS: If you perform the following procedure on a laptop computer, you may reduce the battery life.

USB wont recognize device...


How many other devices are plugged into the laptop?? The power supply can only drive one or two major devices. Try removing other devices and then see if the printer will work. If it does, get a powered usb hub.

USB port problems with hp printer


There are few things to remember using USB.
  • If your System is in hybernation mode, don't remove any attached USB device, because it will damage your USB driver. This is one of the known problem from microsoft.
  • If you have to remove any USB device use 'Safely Remove Hardware'.

To remove currepted USB drivers its not enough to remove your printer drivers.
  1. You should un-install the 'Universal Serial Bus Controllers' from Device Manager.
  2. Then re-boot to clean registry.
  3. Install the 'Universal Serial Bus Controllers' using XP Setup CD.
  4. Then check the Mass storage, PDA etc, it should recognized by XP.
  5. Then install printer driver (don't attach printer to system untill setup finish or setup says to connect).

I think it will fix.
Please let me know your feed-back.

Thanks
Iqbal
