Hi QNX,

             beaglebone black, QNX 6.5SP1, bsp-nto650-ti-beaglebone-sp1-trunk-201209071340, Realtek rtl8192 usb-wifi 
adapter

Please help how to configure USB-WIFI in QNX. A previous post in the network forum suggests to compose a device driver, 
and gives the source code of asix USB-Ethernet as reference.

However, when I look into rtl8192cu linux source code, I don't think I am capable to port it into QNX.

Here is what I am thinking,

According to http://www.qnx.com/developers/docs/6.5.0/index.jsp?topic=%2Fcom.qnx.doc.io-pkt_en_user_guide%
2Fwpa_background.html

io-pkt-v4-hc has 802.11 layer built in, and WPA utilities is able to manage wireless network connections. I am wondering
 whether there is a simple solution and just let build script configures USB-WIFI ?

Currently, in .build script, I have Ethernet and USB-OTG setup as follows,

    io-pkt-v4-hc -dam335x deviceindex=0
    waitfor /dev/socket
    if_up -p -a dm0
    ifconfig dm0 192.168.31.205/16

	display_msg Starting USB OTG Host driver...
	io-usb -vvv -d dm816x-mg ioport=0x47401c00,irq=19
	waitfor /dev/io-usb/io-usb 4


QNX is able to locate the devices,

I tried to follow "Using Wi-Fi with io-pkt"

# io-pkt-v4-hc -d /lib/dll/devnp-ral.so
# ifconfig
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> mtu 33192
	inet 127.0.0.1 netmask 0xff000000

which actually kills dm0, and does not invoke ral0 for wifi as well.

Please advice , thanks in advance.
