Hi again,
Ok I think I know what is going on, and my bad for not seeing earlier,
been in userland only for months. Sorry about that.
You are giving the Linux firmware finder " /lib/firmware/tablet.fw",
which it is thinking of as a filename, and thus not finding it.
You should leave it where it is, but set ctp_firmware to just
"tablet.fw" and let the firmware finding system look in "/lib/firmware/".

Thanks Joe,
I've set that ctp_firmware parameter with relative and complete path,
but the kernel doesn't seem to be able to find it. I was told to use
/lib/firmware, and it fails with the same error, and the kernel I'm
using (3.4.79+), hasn't a very detailed debugging of where it is
searching. Is there a more bullet proof good way to load the
firmware?, or, how can I debug where the kernel is trying to load the
firmware from?
Many thanks in advance!

Hi,
The driver gets the file location from the fex file, from
"ctp_firmware".
There is no point having a standard location because the firmware
device can not be generic. There needs to be a different one for
every hardware configuration.

I have compiled the gslx680 driver, but there is a problem
finding the firmware file (Error -2). Is there an standard
location where the module will search for it?
I'm using a 3.4 kernel, and the F20 image. Many thanks!
