USB DEVICE NOT RECOGNIZED POP up's

HI

I am used to posting about problems, in my previous post if you search my jalal you will get " USB DEVICE NOT RECOGNIZED ERROR" etc ...

with all the discussion ppl told me uninstall and reinstall this and that... i am done with it... i have tried what ever comes to you mind...

Now a fella in his last post said seems like this problem is with northbridge bus chip etc... he said could be numbering problem and its the MB problem...

Now as a doubt i unplugged the connector to the front USB of my casing, and as soon as i unplugged that cord inside my MB, that sudden strange pop's gone

but after these many days with a suddenly lite failure at my side, it appears again

I am not sure what is causing it ???? now i did another trick i went to restart and unchecked the USB devices from BIOS, then rebooted and then restarted again to set it enable from bios and it worked, but i know i will get this USB not recognized by this computer again and again ... so kindly can some1 tell is this bad usb ports or damaged MB...?????

I mean if i narrate this problem to the seller from whom i purchased he will ask me the reason and explanation, so kindly guide me is this MB fault or what is it????

as i said in my previous posts... if you plug all the devices to my USB ports the will work and stil you will get that error and if you remove all the devices from usb ports still you will get it????? as i said i tried all the solutions on net but i fixed for time being this way i mentioned above still want to know the reason what is causing it??? Northbridge chip prob or what????


Kindly guide me with details as last time i asked to educate me abt it so i got no reply???

A explanation of what you did to stop the problem step by step should be enough to tell them it is a bad motherboard just like what you posted told me.
