I am trying to support
802.11b/g Mini Wireless Lan usb2.0 Adapter
fcc id MQ4WUG2700.

I am using Linux kernel 2.6.24 with all wireless modules enabled in kernel. We have also loaded driver rt73usb for this.
But during ifconfig, I am not able to get any interface for wireless LAN.

Any help will be highly appreciated.

I believe that you need to install firmware for this to work. Download the file linked to below. Unzip the file and put the rt73.bin file in th /lib/firmware folder. Look in the output of the dmesg command for firmware errors. It may be looking for it in a different sub-folder of /lib/firmware.

I put firmware under /lib/firmware.
But
"dmesg| grep firmware" shows nothing.

What should I do now ?

waterhead

Which Linux distro are you running? It may make a difference where you put the firmware.

Take a look at the output of dmesg, without the modifiers that I previously added to it. It may shed some light on what the problem is. The output of dmesg is usually too big to post, but if you think you need to, go ahead and post it.
Also post the output of this command. It will show all of the driver modules that you have loaded.

It looks as if you have three wireless cards in this PC:
These module are used by these wireless cards:

Please give me some more info, the output of these commands would be helpful:
