Registering USB WiFi Dongle

We have been reported various WiFi dongles are not supported even though they have same chipset with Hardkernel's WiFi dongle #3 and #4, so we have enhanced to load its driver while registering VID&PID to use.By default, the current Android have two different WiFi dongles which are based Ralink 5572 and Realtek 8188CUS are supported. This is the file maintain the WiFi driver as per VID&PID, you can add your WiFi dongle to here and can be affected on next WiFi turn on.

# cat wifi_id_list.txt                                     
148f 5572 rt5572sta /system/lib/modules/rt5572sta.ko
0bda 8176 8192cu /system/lib/modules/8192cu.ko
0bda 7811 8192cu /system/lib/modules/8192cu.ko
0bda 817a 8192cu /system/lib/modules/8192cu.ko

For example, if you have Realtek 8188CUS based WiFi dongle and its VID&PID are 7392 and 7811, it won't work. So you have add a line below to the file.

7392 7811 8192cu /system/lib/modules/8192cu.ko

Note that the file system is mounted as read only, you must remount before you change the file so that your change can be stored.

# mount -o remount,rw /
# echo "7392 7811 8192cu /system/lib/modules/8192cu.ko" >> /etc/wifi_id_list.txt
# sync
