Uno not recognized by computers via USB

Hello. I am having a similar problem. My arduino uno board worked well for some time but just today when I connected it to my laptop, it won't recogonize the USB . Even there is nothing in Device manager as Unknown device or such. On connecting the board the Led's on the board are blinking but the USB is not recogonized.
PLEASE HELP !!!

@Anuj_Dutt, please do not cross-post.

Have you tried a different USB cable?

Thanks . Got my problem sorted out. :slight_smile:
