Hi, I've a similar issue with BT. brcm4330-patch and config file are installed at the right locations. I found out when booting the cubox-i via power-on then everything works fine. "hcitool scan" is executed successfully and BT devices can be paired.
However after a reboot command (without unplugging the power supply) the internal BT adapter isn't recognized anymore.
"/etc/init.d/brcm4330-patch status" reports an error message:
