Hi,
I'm pretty new in the universe of Pandaboard. My project is to flash an AOSP (Android 4.3.1) on the Pandaboard. So I read a guide about it and I'm in the middle of the fastboot make... My problem is that I can't see the board when I launch the command:

device/ti/panda/usbboot device/ti/panda/bootloader.bin

It keeps me saying this:

root@mh2-K55VD:/panda_android# device/ti/panda/usbboot device/ti/panda/bootloader.bin 
using built-in 2ndstage.bin

unexpected 2ndstage response


I tried to plug and unplug the wires but nothing... I can see it if I launch the command lsusb -vv:
