Driver for WUSB54GC

**notgeekenough** · 11-30-2008

I just bought a WUSB54GC wireless NIC. It worked out of the box and whats more is that I can generally configure it beyond what I expected. i.e put it in monitor mode etc. But, I want to find out what driver it is using. How can I do this?

Thanks

i usually can tell which it is using. Post the output of these two commands, and I should be able to tell.

Code:

lsusb

Code:

lsmod

It's not showing anything. Was the wireless plugged in ?

I do see a few Broadcom wireless modules loading.

The b43 module is the current driver module for Broadcom wireless. It replaces the bcm43xx driver, which I surprisingly see is also loading. I don't believe you would need both of them loading.

HA - forget to connect it, it does look like a rt73

Bus 001 Device 002: ID 13b1:0020 Linksys
[CODE]

Code:

usbcore               146412  5 rt73usb,rt2x00usb,ehci_hcd,ohci_hcd

How about the bcm43xx - anyway to remove it. I had a hell of a time getting wireless working without the ndiswrapper - so I might have at one point installed the xx driver but I cannot remember. By the way, bcm43xx is unblacklisted could that be the reason?

**waterhead** · 12-06-2008

I don't understand why any of the Broadcom wireless modules are loading. Do you have a built-in wireless device? Post the output of this command.

This wireless has full support in Linux. It can do AP, ad-hoc, mesh and Monitor modes. The only catch is that you need to install proprietary firmware before it will work properly. Info on that can be found here:
b43 - Linux Wireless

You don't say what Linux distro you are using, but the b43-fwcutter app can sometimes be downloaded from third party repositories.

As for the bcm43xx module, I wouldn't do annything yet. If the Broadcom wireless works, leave it alone. Otherwise you may want to blacklist it, by putting it in the /etc/modprobe.d/blacklist file.

After making these kinds of changes, please reboot, so that the system can straighten things out during boot.
