Bug Description

The WLI-UC-GN adapter is not functional in Ubuntu 9.10 beta with Linux USB details:

Bus 001 Device 003: ID 0411:015d MelCo., Inc.

With either the live cd or installing, a wireless network does not appear in NetworkManager. It is not clear the support status of this adapter or what driver should be used. Google suggests anything from Ralink 2800 to 3070 drivers. The provided modules do not detect an interface. Building the 2009_0820_RT2870_Linux_STA_V2.2.0.0 drivers fails due to API changes in the Linux kernel. Patching the changes for the new API creates a driver that can be loaded, appears in ifconfig and iwconfig but does not appear in NetworkManager. Running wpa_supplicant makes a "wireless network" heading appear in NetworkManager but other than that is non-functional for scanning networks or joining a network.

Trying to use ndisgtk on the bundled Windows driver CD fails due to not detecting the adapter. However the CD lists what would appear a different product "UCGN" and that gives an error about unable to determine whether an adapter can be detected. Using the ndiswrapper command line shows that the adapter can be detected. Running the ndiswrapper shows a runtime link error due to an undefined function:

Hi all,

We'd like to know whether this is still an issue for you. If so, please can you try with last kernel version, (Lucid upstream) which is located on http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32/

Thanks in advance.

  I tried the newer kernel http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.33/ instead. The device still does not show up here. Specifically, iwconfig does not show it.

I also tested with http://kernel.ubuntu.com/~kernel-ppa/mainline/v2.6.32.9/ - it doesn't work with this either.

I have also attempted to compile the driver: RT3070USB(RT307x) http://www.ralinktech.com/support.php?s=2

This compiles, but I cannot load it. I get the errors:

Okay, here's what is needed:

Download RT3070USB(RT307x) from http://www.ralinktech.com/support.php?s=2

This exists in staging, but we need to patch it. These instructions are based on the version: RT3070_LinuxSTA_V2.3.0.1_20100208


   tar -xvf RT3070_LinuxSTA_V2.3.0.1_20100208.tar.bz2
   cd RT3070_LinuxSTA_V2.3.0.1_20100208
   vi common/rtusb_io.c # remove the DBGPRINT(RT_DEBUG_OFF, ("#\n")); line
   vi os/linux/usb_main_dev.c #add MODULE_LICENSE("GPL"); to the very top
   vi common/rtusb_dev_id.c #add {USB_DEVICE(0x0411,0x015d)}, /* Buffalo Airstation WLI-UC-GN */ to the list
   cp RT2870STA.dat RT3070STA.dat
   sudo make
   sudo make install
   sudo cp os/linux/rt3070sta.ko /lib/modules/2.6.31-20-generic/kernel/drivers/staging/rt3070/rt3070sta.ko
   sudo modprobe rt3070sta

  I took a different approach. I did:

  I cloned the kernel being used in lucid lynx:

  git clone git://kernel.ubuntu.com/ubuntu/ubuntu-lucid.git
  cd ubuntu-lucid
  vi drivers/staging/rt2870/2870_main_dev.c
  # add { USB_DEVICE(0x0411, 0x015D) }, /* Buffalo Airstation NFiniti WLI-UC-GN */ to the list of drivers
  AUTOBUILD=1 fakeroot debian/rules clean binary-debs
  cd ..
  dpkg -i sudo dpkg -i linux-image-2.6.32-17-generic_2.6.32-17.27_i386.deb linux-headers-2.6.32-17-generic_2.6.32-17.27_i386.deb

And that fixed the problem.

I will forward this to <email address hidden> and try to chase it

I have sent the change to add the Buffalo Airstation to upstream. We will see what happens there. The second ID to be added I have kept back (Ralink 2070L) as I would like to get confirmation this works. I have placed kernel which contain both IDs added to the driver to http://people.canonical.com/~smb/lp441990/
If this works, it would be good to open a separate bug report for it and send an email referencing this and the new bug to <email address hidden>. Thanks.

Stefan, please double-check my instructions :)
