Public bug reported:

Binary package hint: linux-firmware

Hi,

A wireless usb key (D-LINK DWA-140, rev B2) doesn't work anymore on Natty. It 
was working fine on maverick.
Quote from the kernel log:
May 14 17:03:57 pegasus kernel: [   19.313276] phy1 -> 
rt2x00lib_request_firmware: Error - Current firmware does not support detected 
chipset.

Replacing /lib/firmware/rt2870.bin with the one from Ralink ("Firmware
RT28XX/RT30XX USB series (RT2870/RT2770/RT3572/RT3070)" version 22,
dated 03/31/2010 on http://www.ralinktech.com/support.php?s=2) lets it
work as expected.

Thanks.
