I also seem to be having issues with firmware loading. Any clues would
be helpful.
I have a Gumstix Overo Fire with a built in libertas_sdio, and an ar9170usb
It finds the libertas firmware just fine, but not the ar9170 firmware.
I'm using a 2.6.29 kernel. This worked fine with
compat-wireless-2009-11-17. All the firmware files are in /lib/firmware.
Here's some dmesg output:
