Hello Pablo, Iván,

thank you very much for your work. With this kernel everything seems to 
work: 8CPUs, Ethernet, USBtoSATA, not tested: HDMI

I'm now in the process to copy everything from SD-Card to the onboard 
EMMC, so I can boot from it.


With your work I have a powerfull device.

Thanks
Andreas

(thinking what can I do with the cubietruck plus: Time-Server (DCF77) ? 
DNS-Server? Pi-Hole? ...?)

PS: sometimes I get these messages in the syslog:

No USB-Device plugged in.
