    Question RPi, no USB wifi, multiple NICs

    I've installed Kali on an SD card and it boots on a Raspberry Pi. During boot, eth0 pulls an IP just fine and I can log in locally, but my problem is that wlan0 never comes up. I have four different USB wifi NICs; they all show in "lsusb" but none come up as wlan0. Right now I'm sharing the wifi from a separate computer to its ethernet port so that I can SSH into the RPi and it can get online to pull packages as necessary. I'm wondering if I'm missing some fundamental networking command in Kali or if there's something specific about the architecture of the Raspberry Pi that I'm not seeing... either way, here's what I'm seeing...

    I have these network cards available (these names from the label on the card or its packaging):
    1) Edimax EW-7811Un
    2) TP-Link TL-WN422G
    3) Alfa AWUS036H
    4) Belkin F5D7050

    According to lsusb, those cards have the following chipsets:
    1) Edimax EW-7811Un:
    Bus 001 Device 008: ID 7392:7811 Edimax Technology Co., Ltd EW-7811Un 802.11n Wireless Adapter [Realtek RTL8188CUS]

    2) TP-Link TL-WN422G:
    Bus 001 Device 007: ID 0cf3:1006 Atheros Communications, Inc. TP-Link TL-WN322G v3 / TL-WN422G v2 802.11g [Atheros AR9271]

    3) Alfa AWUS036H
    Bus 001 Device 010: ID 0bda:8187 Realtek Semiconductor Corp. RTL8187 Wireless Adapter

    4) Belkin F5D7050
    Bus 001 Device 009: ID 050d:705c Belkin Components F5D7050 Wireless G Adapter v4000 [Zydas ZD1211B]

    Output of various commands: (with all four NICs plugged in via a powered hub)

    I've added wlan0 to /etc/network/interfaces:
    auto lo
    iface lo inet loopback
    auto eth0
    iface eth0 inet dhcp
    auto wlan0
    iface wlan0 inet dhcp

    root@kali:~# iwconfig
    lo        no wireless extensions.
    eth0      no wireless extensions.
    I see the NICs, but get no error codes in:
    "dmesg | tail -30"

    I've tried all sorts of things from other pages, installing "wicd" and "network-manager", installing and moving firmware-realtek, ath9k_htc, and a few others... What am I missing?

    If this is one of those "... it's been answered elsewhere" kinds of problems, I'm open to reading up on a few key terms pointing me in the right direction and I'll do my own research.

    I have identical problems. Seems to be something to do with the Kali RPi build, as other RPi distros (e.g. the standard Wheezy) work fine with the same USB NIC. My RPi is the model B 512MB RAM.

    Ah, good point, I should have mentioned the RPi build in my original message. Yes, it's the Model B, 512MB version. Does that help anyone?

    I just saw that there's a 1.05 image available for the Raspberry Pi, that seems to have fixed my issues! Yay!

    I have about the same issue and have lately launch an upgrade and still facing same problem. I can see the Wificard but cannot use it with airxxx-ng commands which keep saying that i cannot see any wifi card.
