TLDR - In addition to the previous responses  There might be a problem with the version of the fastboot command  Try to download the newest one via Android SDK Manager instead of default one available in the OS repository    There is one more thing you can do to fix this issue  I had the similar problem when trying to flash Nexus Player  All the adb commands we working fine while in normal boot mode  However  after switching to fastboot mode I wasn t able to execute fastboot commands  My device was not visible in the output of the fastboot devices command  I ve set the right rules in  etc udev rules d 11-android rules file  The lsusb command showed that the device has been pluged in   The soultion was quite simple  I ve downloaded the the fastboot via Android Studio s SDK Manager instead of using the default one available in Ubuntu packages   All you need is sdkmanager  Download the Android SDK Platform Tools and replace the default  usr bin fastboot with the new one

I had the same issue  but I was running Ubuntu 12 04 through a VM   I am using a Nexus 10   I had added the usb device as a filter for the VM  using virtual box in the virtual machine s settings    The device I had added was  samsung Nexus 10    The problem is that once the device is in fastboot mode  it shows up as a different device    Google  Inc Android 1 0    So doing  lsusb  in the VM showed no device connected  and obviously  fastboot devices  returned nothing until I added the  second  device as a filter for the VM as well   Hope this helps someone

If you got nothing when inputted fastboot devices  it meaned you devices fail to enter fastboot model  Make sure that you enter fastboot model via press these three button simultaneously  power key  volume key both     and  -    Then you can see you devices via fastboot devices and continue to flash your devices   note I entered fastboot model only pressed  power key  and  -  key before  and present the same problem
