    Enable USB after "disabled" in BIOS


      STCK1A32WFCR ( FC0018.BIO )


      I'm currently trying to get the stick booting Ubuntu (15.04) headless, without a screen connected to the HDMI port, but without any luck.


      As a desperate measure i tried to disable USB in the BIOS settings. But that seems to have been a fatal misstake... now I don't have any input device available, even PRE-boot. In other words, I cannot get into the BIOS setup anymore. I tried to remove the CMOS battery, and I get "CMOS checksum failed" but the USB(-keyboard) is still not available... Any idéas how to resolve this?


      The operating system is booting, but since i used a USB-to-ethernet adapter i currently have no way to connect to the linux console via ssh either...


      Is it possible to get a serial console somehow? I can see a /dev/ttyS0 device when booting linux, but can't find any connectors or points to connect a serial cable.

          Was a bit too quick here, found the solution for this. Using the power-button BIOS upgrade procedure brought the USB connection back to life.

          1. Press and hold the power button down for 3 seconds. Release it before the 4 second shutdown override.



          On the other hand, has anyone managed to get the stick booting headless in "Ubuntu mode" ? It seems that it gets stuck somewhere, but i cannot determine where in the boot process. And if I reconnect the display after power-on, there is NO picture at all... And the operating-system does not boot, in example there is no connectivity through the USB-to-ethernet adapter.


          I have only tried Ubuntu 15.04 with numerous different grub options, since the 14.04 Installer does'nt seem to recognize the mmcblk storage device out of the box.

            15.04 isn't supported by the device, only 14.04 LTS 64 bit. I can say that version boots and runs just fine for me off a microSD card. Didn't try it headless though.
