[SOLVED] package "hidapi" & kernel module "hidraw"

71GA · 2014-11-26 20:22:58

Hello,

I am currently dealing with openocd and guys at IRC told me that I need to enable
kernel module "hidraw". How can I do this on Arch?

I tried to nstall package "hidapi" from AUR and add line "hidraw" inside a file
"/etc/modules-load.d/MODULES-load.conf" but it didn't load at startup.

Any sugestions?

Can you load it manually?

Edit: Are you sure the package does provide the module?

Edit 2: Arch seems to ship with the module compiled in:

$ zgrep -i hidraw /proc/config.gz
CONFIG_HIDRAW=y

How do you know it's not working?

I am not sure if package provides it. Guys on openocd said I need hidapi package and module hidraw.
Is there a way to check which kernel modules does a package provide? Where can I find these info?

I get same output.

$ zgrep -i hidraw /proc/config.gz
CONFIG_HIDRAW=y

Does "y" mean hidraw is running? I assume it is not running on my machine because i get nothing after executing:

lsmod | grep hidraw

'pacman -Ql hidapi' will show you all files and directories this package provides.
IIRC lsmod works with loadable modules only. Since the stock Arch kernel has 'CONFIG_HIDRAW=y' and not 'CONFIG_HIDRAW=m' and https://github.com/signal11/hidapi mentions hidraw driver (if I understand, it's a different animal from a module), lsmod won't show it.

What doesn't work? Do you get any errors from openocd or some other application?

So lsmod doesn't list all the modules I see. I didn't know that. Is there any command to list all modules (loadable and other "animals" like you said it)?
Yes openocd is giving me a headacke but this is not appropriate to be discused here. I will rather ask on openocd IRC chanel.

Thank you.

/proc/config.gz tells you what's compiled in, what's not and what's enabled as a loadable module.
On openocd IRC channel you should ask what exactly are you supposed to do / to look for. Is 'CONFIG_HIDRAW=y' all there is to it?
Ask them if the hidapi package is necessary.
