My sony VGN N220E does not detect external devices

my laptop does not detect external devices,mostly mp3 players.
Recently i bought creative zen v mp3 player ,and after installing software cd ,when i connected the player to laptop ,it showed that the system can not detect any device software ,and asked to insert the cd which came along with the player ,i did ,,but no response .
Initially i thought there might be problem with the player ,or it might not support vista ,but when i tried the same in another vista program laptop (HP) it worked ,and i even tried with other mp3 players like sony ,sanasa etc .
And i would like to mention that there was no problem while installing software from cd ,and the time i would connect player ,it shows no device software located ,,and it wont detect my player .

please,can you provide me with a solution .

thank you

Re: my sony VGN N220E does not detect external devices

Try reinstalling your usb ports.

1. goto desktop, right click on my computer and press manage.
2. goto the device manager, find the usb devices / ports.
3. Make sure you are useing a ps2 mouse / keyboard since if your mouse/keyboard is connected to usb they will stop working untill your pc is restarted and the devices are reinstalled.
4. Uninstall all usb devices.
5. after all usb devices are uninstalled reboot the pc.

If the problem is with your drivers ( your pc detects the mp3 player but no drivers found) Download the newest drivers for your product and operateing system from the vendors website.

Doesn't have a mass storage controller for my laptop sony vaio vgn-n220e

If memory serves me, the mass storage controller is part of the chipset software. Here is a link to the driver download for you laptop. Choose the OS, and then look under motherboard for the chipset driver. While you are there, you might even update all your hardware drivers.

Hope this helps

Battery shows full charge, but when unplugged drains within minutes sonny vaio vgn-n220e

Battery most likely has dead cells, the live cell that is still working is showing 100% but does not enough juice to keep the computer running by itself. You need a new battery.

Charging problem in sony vaio VGN-N220E

sounds more like your dc jack(where you insert your plug into the laptop ) is going bad. If you have a multimeter the first thing to test would be your charger to make sure it isnt faulty. If the charger is fine then it is most certainly the dc jack. Replacing the dc jack is best to be left to someone who specializes in that kind of repair but if you know how to solder it may be something that you can do yourself. click here for more info on dc jacks.
