Hello everybody,

I received the BBB from my friend and i have a problem.

I was trying to connect with bbb by usb cable but this is not working.

When I connecting the bbb without the SD card the LED_Power is working on and i heard the Windows sound of connected device, but other leds are dead.
When I connecting the bbb with the SD card with this os installed - " Debian 7.5 (BeagleBone Black - 2GB eMMC) 2014-05-14 " for eMMC flasher, the BBB is dead and the LED_Power blink for 1 second and after that is turned off. I'm pushing the boot button before connecting to the power but this still not working.

I don't know what to do more with that problem.
