USB wireless adapter auto startup

[BenLau <ben.lau@sw-linux.com>]

Hi all!

  I recently got a USB wireless adapter( GW-US11H) . It required a
patched version of linux-wlan-ng. I have patched the source and install
it  After I added the configuration of wlan0 to /etc/network/interfaces
, and then I can use "ifup wlan0" to start up the device and gain IP
through DHCP successfully. However , I would like the device can start
up autoamatically. How can I make debian be able to do so?

Thanks for any help!

p.s that is my /etc/network/interfaces

iface wlan0 inet dhcp
        wireless_mode managed
        wireless_nick mylaptop
        wireless_enc off
        wireless_channel 1
