libertas: failed to load firmware

[richard]

Hi,

I've built a custom kernel based on Linux 2.6.37-rc8 for my Guruplug standard and all looks to be good apart from the wireless driver,
During the kernel boot process I get the following message:

libertas: failed to load firmware                                               
libertas_sdio: probe of mmc0:0001:1 failed with error -5

I have copied the sd8688.bin, and sd8688_helper.bin to the /lib/firmware. A file named sd_helper.bin is also there.

Any clues?

What does error -5 mean?


Thanks

Rich
