[Help] usb wifi issues

[dutor]

I want use wifi on my Raspberry Pi, using the TL-WN723N usb adapter. But it didn't work for me, and I could not find the 'wlan0' in the iwconfig output. Here are the related logs from dmesg:

rtl8192cu:_rtl92cu_read_adapter_info():<0-0> EEPROM ID(0x0) is invalid!!
rtlwifi: rx_max_size 15360, rx_urb_num 8, in_ep 1
ieee80211 phy0: Selected rate control algorithm 'rtl_rc'
usbcore: registered new interface driver rtl8192cu
rtl8192cu: MAC auto ON okay!
rtl8192cu:rtl92c_llt_write():<0-0> Failed to polling write LLT done at address 0! _LLT_OP_VALUE(3)
rtl8192cu: ===> rtl92c_init_llt_table #1 fail
rtl8192cu:_rtl92cu_init_mac():<0-0> Failed to init LLT Table!
rtl8192cu:rtl92cu_hw_init():<0-0> init mac failed!

Anyone encountered this issue before?
FYI. I use the 2012-12-16.wheezy-raspbian distribution.
Thanks in advance!
