Bug Description

In order to get a new usb Wifi dongle working, I installed the linux-image-generic-lts-backport-oneiric package on an existing Ubuntu lucid 10.4 system.

lsusb had reported the device as "13d3:3310 IMC Networks", which uses a r8712u chip. Supported from 2.6.37 kernels.

Once the new kernel loaded, the device was correctly identified and
[ 87.824770] r8712u: Loading firmware from "rtlwifi/rtl8712u.bin"
appeared in /var/log/messages

However, the device never became ready. There appeared to be no file

/lib/firmware/rtlwifi/rtl8712u.bin present on the system.

Downloading the firmware from http://git.kernel.org/?p=linux/kernel/git/dwmw2/linux-firmware.git;a=tree;f=rtlwifi
and installing as /lib/firmware/rtlwifi/rtl8712u.bin fixes the problem.

Looks like there is a missing firmware dependency in the backport and possibly other packages using the same kernel.
