Can't work on Ubuntu 13.04 with kernel 3.8.13

[jewsuscn]

After compile the driver code, and insmod 8188eu.ko, the NIC can't work up automatically, when I execute the follow command "ifconfig wlan13 up", Occur the error: "SIOCSIFFLAGS: Operation not permitted."
I used Ubuntu 13.04 Linux kernel version : 3.8.13.16 NIC : Mercury MW150us v2(Chipset: RTL8188eu)

I find a old version rtl8188eu driver code in google, After compile and load the driver module , my NIC(Mercury MW150us v2) can work well as a wireless station, but when i config it an a SoftAP using hostapd-0.8, I can scan this AP on other station workstation, but can't connect to it even it work on Open mode. When using WPA/WPA2, it always occurs Authentication failed.

  The hostapd log as follow:

/opt/rtl_hostapd_open.conf file:

Who can help me?

I have no idea if soft AP works with this driver or not. If you really want to use it, you will likely need to debug it yourself. One theory is that the firmware will not support an AP, but I do not know if that is correct.

At the moment, I have no time to test if the RTL8188EU will work as an AP.

But there are many people in internet successfully configured.SoftAP with RTL8188eu, e.g: http://www.cnblogs.com/XDJjy/p/3866534.html

When i copy the fireware rtl8188eufw.bin to /lib/firmware/rtlwifi, it can work as a wireless workstation successfully, but after i run hostapd and udhcpd, I can't scan the softAP anymore, the kernel log message as following:

[jewsuscn]

Why? It indicate that the firmware rtl8188eufw.bin can't support SoftAP? What can i do next step?
