firmware not working

[tisdall]

I'm getting Request firmware failed with error 0xfffffffe but I'm not sure why.

I think that's the error you get when you forget to put the firmware .bin in the right place, but I did copy it over.

Is there something obvious I'm missing?

I got the same error. Any updates?

When you reply to a two-year old message, you can hardly appear to have the same problem.

There are two reasons for missing firmware: (1) The listed file does not exist in /lib/firmware. (2) The driver is included in your initrd, but the firmware is not. The test for #2 is to unload/reload the driver.

Thank for fast reply. Like in your documentation mentioned the firmware was missing.
