My experience is with Fedora Core 3, not debian, but I am happily
using this driver package with a Belkin USB wireless adapter. 
My device is displayed with
    $ /sbin/lsusb
    Bus 002 Device 001: ID 0000:0000  
    Bus 001 Device 003: ID 050d:0050 Belkin Components 
    Bus 001 Device 002: ID 03f0:2811 Hewlett-Packard PSC2100
    Bus 001 Device 001: ID 0000:0000  
so it has a vendor:product identifier of 050d:0050.

I think you need these additional items:

1)  In /etc/modprobe.conf
    alias wlan0 at76c503-rfmd

2)  A configuration file for the wlan0 interface.  Mine is in
/etc/sysconfig/network-scripts/ifcfg-wlan0:
    $ cat ifcfg-wlan0
    # Please read /usr/share/doc/initscripts-*/sysconfig.txt
    # for the documentation of these parameters.
    IPV6INIT=no
    ONBOOT=yes
    USERCTL=yes
    PEERDNS=yes
    GATEWAY=192.168.2.1
    TYPE=Wireless
    DEVICE=wlan0
    HWADDR=00:30:bd:65:c0:bd
    BOOTPROTO=dhcp
    NETMASK=255.255.255.0
    DHCP_HOSTNAME=datbird
    IPADDR=192.168.2.115
    DOMAIN=
    ESSID=DATIX
    CHANNEL=7
    MODE=Managed
    RATE=Auto

3)  Try to activate it (as root):
    ifup wlan0

4)  See if it came up:
    ifconfig
        shows all currently active interfaces
    iwconfig
        shows wireless parameters of active interfaces

5)  See if debian honors the 'ONBOOT=yes' and automatically activates
the interface when you reboot.
