Hi Navin, I thought someone had replied to you, but it seems I was mistaken. Sorry!
So what you're seeing is that your USRP disappears from your USB port. That's almost certainly a problem with your virtualizer. I don't recommend using a B-series device in a VMware VM. The USB handthrough overhead will be killing all performance. I don't think running a low- latency hardware-close piece of software like an enodeB in a consumer- grade, default-setup VM is going to work.
