For our application, we wish to decode 802.11 packets on a consumer 
grade wifi module.  I'm reaching out to anyone who has replaced the 
Gumstix Overo board in the E100-series machine with a wifi-enabled 
Gumstix board, namely the Overo FireSTORM.  I have already replaced the 
board in our machine, but have been unable to get the wifi module to 
work (Everything else seems to work perfectly).

The FireSTORM has the exact same configuration as the packaged Gumstix 
board, but with the addition of a wifi module soldered on. I see no 
reason why reason it shouldn't work, and suspect it is a driver problem.

Namely, in my driver log, I found the following error:

lib80211: common routines for IEEE802.11 drivers
lib80211_crypt: registered algorithm 'NULL'
cfg80211: Calling CRDA to update world regulatory domain
libertas_sdio: Libertas SDIO driver
libertas_sdio: Copyright Pierre Ossman
libertas_sdio: failed to find firmware (-2)
libertas_sdio: probe of mmc1:0001:1 failed with error -2

Has anyone else attempted to do this?  I've tried downloading the 
relevant linux-firmware files and placing them in /lib/firmware, but 
that didn't seem to work (same error).
