BBB does not recognize the serial/USB cable

I have followed those instructions, and it took over 45 min to complete till I had all four LED light.

Just a note here, when I first looked to see if the LEDS were lit, they were not. So I placed back in the SD card and rebooted, all the LED lights were on as I described to you. I then removed the SD card and rebooted, the LED still lit up as such. I now however do not get that ARM 335x USB appearing and disappearing anymore, but I also do not have any storage devices showing up either. Nor anything new populates my device manager window.

I would go back and repeat the flashing. The SD insert and removal can mess things up.
