Creating wlan interface on debian 7


I am running Debian 7 under VMWare and want direct wifi connection. I have a USB wifi device plugged in and the relevant module (rtl8192cu) seems to be loaded (automatically). lsmod says the module is unused.

Code:
    root@debian7:~# uname -a
    Linux debian7 3.2.0-4-amd64 #1 SMP Debian 3.2.63-2+deb7u1 x86_64 GNU/Linux
    
    root@debian7:~# lsmod 
    Module                  Size  Used by
    rtl8192cu              74897  0 
    rtlwifi                81393  1 rtl8192cu
    rtl8192c_common        52602  1 rtl8192cu
    mac80211              192806  3 rtl8192c_common,rtlwifi,rtl8192cu
    cfg80211              137243  2 mac80211,rtlwifi
    
    root@debian7:~# lsusb
    ...
    Bus 001 Device 002: ID 20f4:648b TRENDnet TEW-648UBM 802.11n 150Mbps Micro Wireless N Adapter [Realtek RTL8188CUS]
Yet there is no wlan interface:

Code:
root@debian7:~# ip a
    1: lo: <LOOPBACK,UP,LOWER_UP> mtu 16436 qdisc noqueue state UNKNOWN 
        link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
        inet 127.0.0.1/8 scope host lo
        inet6 ::1/128 scope host 
           valid_lft forever preferred_lft forever
    2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
        link/ether 00:0c:29:2e:d5:3e brd ff:ff:ff:ff:ff:ff
        inet 172.16.233.215/24 brd 172.16.233.255 scope global eth0
        inet6 fe80::20c:29ff:fe2e:d53e/64 scope link 
           valid_lft forever preferred_lft forever
    
    root@debian7:~# iwconfig
    lo        no wireless extensions.
    
    eth0      no wireless extensions.
How do I get the wlan interface to appear? I tried adding it to /etc/network/interfaces without success.

Hi,

instructions for that device on Debian 7 are at https://wiki.debian.org/rtl819x#Debian_7_.22Wheezy.22

Post back if you have any problems.

Thanks. It was the firmware (firmware-realtek from non-free) that was missing. The output from dmesg contained an indicative error message.
