Not working properly

I’m starting with beaglebone now and i’m stacked into a problem with it. When i connect my board to PC with USB cable it reconized but i can’t access the SD card and the isn’t working too.

The Led of RJ-45 is OK and there’s a led that is blinking too.

Thanks for answers and sorry for the poor english i’m not a native speaker.

The “USB Gadget” Ethernet address should be on. If your host OS won’t mount the SD card, might be difficult (impossible) to install the drivers that your OS might need for the gadget interface. Check the site to try and find a link to downloading the drivers separately.
