Dear Peter & all,

On Linux I can install [hidraw] 0.1.0 via Deken. The external loads
without errors, but I am not getting any response clicking the
"listdevices" message.

As Lucas reported in the other thread, this works just fine for me. (Do you see any USB devices, HID or not, when you `lsusb -v` on the command line?)



Colleagues have tried to find [hid] for their newer apple cpu's
without success unless they start Pd under the Rosetta emulation and
install Albert's amd64-32 package.

Good to know, and sorry for making you depend on Rosetta. I don't have much time to finally get the build system for [hid] updated, nor have access to Apple Silicon. Some kind soul on this list even offered to compile things for me -- I've gotten nowhere with the required thinking and coding since, I apologize!



Interestingly there exists a hid Deken package for Darwin-arm64-32
http://deken.puredata.info/library/hid/0.1.0
but it is not displayed in Pd's built-in search engine on OS X as far as
I can remember (maybe someone can check this?).

Deken on pd 0.52.1 (a self-built version IIRC) on Linux, when configured to *not* hide packages for foreign platforms, gives me this:

hid[v0.1.0](Darwin-arm64-32).dek

On Windows there is only [hidraw], correct?

At least there is no [hid]. The sources and makefile include mentions of "cygwin", but I don't have a Windows machine either. Even if I could build it with mingw, I couldn't test.



General question:
What would be a reason to prefer [hidraw] over [hid]?

Quoting a previous thread on this list, https://lists.puredata.info/pipermail/pd-list/2022-11/131618.html

"""
My comparison AFAICT (from working on [hid] a little [...]):

[hidraw]
* is more cross-platform, including Windows
* has a way more modern code base and build system
* offers less "semantic" output -- in the sense that [hidraw] gives you
event codes that you process in your patch yourself, whereas [hid]
decodes many of the possible button presses and other events
* uses an external library, libusb/hidabi, for its functions -- [hid]
only uses OS functions and headers iirc
"""

The mail goes on to suggest the creation of a wiki page "or other documentation item [...] listing the different possibilities of working with USB HID devices in Pd."

I sat down and tried my hand at this, what do you think? https://puredata.info/Members/albert/USB

Suggestions welcome, both content-wise and in terms where to best put this.



How do I parse the output of [hidraw]?

My own dabblings with [hidraw] have followed this approximate path:
* Try to get data off the USB device at all
* Then play around and see what values the different buttons, knobs, .... will send * Construct a patch to translate from raw HID data to useful Pure Data control lines.

Best regards,
  Albert.
