sorry for the double forum post, just starting a new thread for clarity.

I'm trying to use a USB joystick with pure data on my headless Raspberry Pi. I've got the patch working on my laptop just fine.

I've installed the pd-hid external on my Raspberry Pi, but the joystick doesn't do anything in the patch. The external loads when I start up Pd, but I don't get any input information from the joystick into Pd.

One theory I have is that the version of [hid] is different on the Raspberry Pi repo vs. Deken? On Raspberry Pi it is says:

[hid] 0.7, written by Hans-Christoph Steiner <hans@eds.org>
    compiled for Debian on 2022/12/07 at 09:43:35 UTC```

Whereas the version on Deken is "hidv0.1.0.dek".

Could these be different? Or is there something else entirely that I'm missing?

Maybe it is related to permissions for reading dev/input devices under linux ?
I had trouble with hidio when I passed from ubuntu 18.04 to 20.04. With Ubuntu 20.04, access to /dev/input/*** is denied to normal user.
It 's not the same external nor the same OS, but it may be the same issue.
In my case, a workaround was to add current user as member of the input group, in order to have permission to read the touchscreen device:

sudo gpasswd -a $USER input

EDIT Anyway, not sure of my command. Cannot remember where I found it...

as an update to this: it's definitely because the [hid] object that is in Deken for macOS is not the same [hid] object that is on the Raspbian repo. It's confusing! I was able to make it work by copying some old screenshots I found of the old [hid] object, and having two different versions of the patch with [hid] object in action.
