invisible/undetectable beaglebone on ubuntu & window

[nida]

I was recently trying to install Python library from adafruit's website from their tutorials. The library was to help the user to access the GIOPs and generate PWM.

Today when I plug my beaglebone into my computer using USB cable, the beagle is not recognized/detected by the computer. I tried different computers and different cables. The current cable is working fine. The Beaglebone Black is even powered up and flashes its LEDS in the normal progression like it should but it is just not being detected by the computer.

Does the computer recognize the BBB as a connected device?

[nida]

no, I have connected it with 4 different laptops none of them recognize it

[nida]

computer never recognize the device neither in window (followed the post beagleboard.org/getting-started ) nor in ubuntu (accessing it via ssh command on terminal it display "network cant be connected")

That sounds like a hardware problem.

Both CircuitCo and Element14 (BBB makers) insist on handling RMAs directly. Which version do you have?
