For kernel versions from 3.7 to at least 3.9, make sure to build the modules for the webcam and wifi devices.

When running make menuconfig, check the following:

Device Drivers --> Multimedia Support --> Media USB Adapters --> USB Video Class (UVC) -->

• UVC input events device support

Device Drivers --> Network device support --> Wireless LAN --> Atheros Wireless Cards --> Atheros 802.11n wireless cards support -->

• Atheros ath9k PCI/PCIe bus support
• Atheros ath9k AHB bus support
• Atheros ath9k rate control

There was an issue of not being able to shut down. When shutting down, the system would restart itself. Here's a fix I found on a blog (http://www.pbehnke.com/main/node/11):

1. Create an init script in /etc/init.d (Example: create a file named /etc/init.d/haltusbpower)
2. Put the following in the script:

   #! /bin/bash
   #
   # haltusbpower init script
   #
   # chkconfig: 345 99 20
   # description: A script to act as a workaround for the bug in the runtime power management module, which causes my acer aspire v5-571 laptop to restart after shutting down.
   #
   ### BEGIN INIT INFO
   # Provides: haltusbpower
   # Default-Stop: 0 1 3 5
   # Short-Description: Halt USB Powersave mode
   # Description: A script to halt usb power control.
   ### END INIT INFO
   
   # Source function library.
   . /etc/init.d/functions
   
   # Bus list for the runtime power management module.
   buslist="usb"
   
   # See how we were called.
   case "$1" in
     start)
       echo "USB bug fix active"
       #no-op on startup
       ;;
     stop)
       echo "Turning off USB Power Control"
       for bus in $buslist; do
           for i in /sys/bus/$bus/devices/*/power/control; do
               echo on > $i
               done
       done
       ;;
     *)
       echo "Usage: /etc/init.d/haltusbpower {start|stop}"
       exit 1
       ;;
   esac
   exit 0

3. Create a symbolic link in /etc/rc0.d to the script you created in the previous step.

   Example:

   ln -s /etc/init.d/haltusbpower /etc/rc0.d/haltusbpower
