I wanted to format my usb, so I opened disk-utility to format. But the formatting process wasn't complete and gave me some error. Now my usb isn't detected; please help.

Please find the screen shot from dmesg:-

I upgraded to 12.04.1 yesterday, could that be a cause of the problem?

Try plugging Your USB drive in Other USB port of your system. – atenz Aug 25 '12 at 6:58
Shut down, start up, try again. If same problem, either port or drive died... – izx Aug 25 '12 at 7:02
i've tried plugging the usb onto all the ports, its not being detected.Is there any logs I can check that will tell me what went wrong and how can I prevent the same in future? I have tried restarting the laptop. – Ankit Aug 25 '12 at 7:08

Try this - in terminal type:-

sudo killall udisks

then load gparted if you have it on your system - format to desired file system.

This command has helped with a lot of USB problems - it may help you.

good luck Mal
