Bug description:
  I'm using a D-Link DWA 140 USB WLAN stick which worked fine under
  Maverick. On Natty the NetworkManager displays "firmware missing",
  connecting to an access point is not possible. This is not only
  occuring under Natty, it also doesn't work with Maverick if you
  install the 2.6.38 mainline kernel.

  There is a workaround for this problem. A quick "lsmod | grep rt"
  shows the following:

  parport_pc	36959 	0
  parport		46458 	3 parport_pc,ppdev,lp
  rt2870sta 	450556 	0
  rt2800usb 	18235 	0
  rt2800lib 	45181 	1 rt2800usb
  crc_ccitt 	12667 	2 rt2870sta,rt2800lib
  rt2x00usb 	20330 	1 rt2800usb
  rt2x00lib 	49235 	3 rt2800usb,rt2800lib,rt2x00usb
  mac80211 	294370 	3 rt2800lib,rt2x00usb,rt2x00lib
  cfg80211 	178528 	2 rt2x00lib,mac80211

  rt2870sta is the right module which is also loaded in Maverick/2.6.35
  and which is needed for the stick to work. rt2800usb, rt2800lib,
  rt2x00usb and rt2x00lib are wrong modules which are causing the
  problem. So we have to unload all the ralink-related modules:

  sudo modprobe -rf rt2870sta rt2800usb rt2800lib rt2x00usb rt2x00lib

  Then we can load the right module:

  sudo modprobe rt2870sta

  Now it should be possible to connect to an access point with the
  NetworkManager. To make this change permanent, we have to blacklist
  all the wrong modules in the /etc/modprobe.d/blacklist.conf file.

  It would be awesome if the developers fix this until natty release so
  it'll be working out-of-the-box. :-)
