Usually this means the computer saw that something was plugged into the USB port, but it doesn't know what device it is. It will require device drivers from NEC to recognize the drive. If your drive came with a driver CD, install these drivers. If the drive was working before, but now it's not, reinstall the drivers. If this does not fix the problem, then most likely either your drive is bad, or else your registry has become corrupted. Try another USB drive and see if your USB port is working, that is another possibility.
This may sound stupid but make sure it is plugged in. Check the operating system and hardware requirements, if they don't meet the requirements, software will not recognize the device. Try different usb ports because sometimes computers have selective hearing and make sure your computer is initially recognizing the device when it is plugged in. If all else fails, don't try to install the software and head over to computer/my computer in the start menu. Right click and select properties. Click device manager in the hardware section or the bar to the left and look in the cd drive section. If you see your drive, right click and try any option about installing.
The USB device is not recognized because the proper software for the computer to read the devices memory is not installed. Visit the manufacturers websites for drivers and software downloads and install for proper device model.
verify that the USB port is working, you may also try it on another machine to see if it works, you may have a corrupt driver for your usb port. If it works on another machine then uninstall and reinstall updated drivers for your usb ports. I hope this helps, Good luck.
Sounds like a possible problem with the usb ports. Does the usb drive work on other pc's? If so, does your laptop recognize other usb devices (flash drives, mouse, keyboard etc.)?
If your laptop won't recognize other usb devices all the time, try this: go into device manager, go to the bottom, expand 'universal serial bus controllers'. Starting at the bottom of the list, right click on each item and left-click 'delete'. At some point you will likely lose your mouse/tochpad as it is probably an internal usb device. If this happens, press the power button on the laptop once to shut it down. Restart it, and windows will re-detect the deleted usb hubs and hopefully fix the problem. If this doesn't do it, go back and delete the other usb root hubs and host controllers. This is totally safe for your system and often fixes this issue. Windows will always re-detect hardware at boot time.
you could try removing the drivers from your device manager by going through contol panel or by right-clicking on My Computer and then on the hardware tab. you would find it under cd/dvd rom drives.Just right click and click on uninstall. Then if you dont have your driver disk you might be able to download it from softpedia.com. If you have installed drivers more than once you might be able to roll-back drivers but the best bet would be to just uninstall and re-install the drivers.
Firstly the ide controllers you mention are only for internal devices like you hardrive and internal dvd writers, not usb peripherals.
If you have service pack 2 on your system there should be no problem it could be that your usb port is faulting.
You can locate the drivers that are on your girlfriends pc, they will be exactly in the location that you have typed in your post and copy them to a disc and paste them into your windows operating system in the same folder eg
C:\WINDOWS\system32\DRIVERS and the other mentioned driver to see if it works.
If not try another usb port or go to My computer>right click>properties>hardware tab>device manager and at the bottom of the list you will see everything to do with your usb port controllers.
Right click on each controller and select uninstal and then restart your pc, the drivers that you put on your system should then automatically load when your pc finds the usb controllers again on start up.
