Bealgebone black disconnects USB

Hi All

I’m running ubuntu 12.04 on my beaglebone black. Every now and again it disconnects from the USB. I read somewhere in this forum that the kernel is buggy for this release. So I’m upgrading to 14.04. But i just want to know if this is a known problem and if upgrading to 14.04 will rectify the USB issues.

Any help is appreciated.
