Turn device into an HID device #6

Open Skewjo opened 3 years ago

I believe HID functionality may run at lower level layers of the OS and may achieve different (faster) read/write times, especially for games.

I'm still a bit confused on what exactly the differences are between COM and HID devices (yeah, yeah, I know that's redundant), but from what I can tell, an HID can(should?) be recognized in a machine's BIOS. Apparently obtaining "true" HID behavior through an Arduino is not quite straightforward.

This forum post: https://forum.arduino.cc/index.php?topic=565711.0 Leads to this forum post: https://forum.arduino.cc/index.php?topic=545288.msg3717028#msg3717028 Which leads to this repo: https://github.com/gdsports/usb-metamorph/tree/master/USBSerPassThruLine

The long and short of it is that the guy is trying to get an Arduino to function as a keyboard on some device, but: image

Is composite where COM comes from?? I thought COM meant "Communication"... Anyways.

In the first forum post the user gdsports gives a few instructions on how to get the device changed over to HID. Going to attempt to follow them today.

Also, here's the main open source HID library that Google will guide you to: https://github.com/NicoHood/HID

I'm unsure what the difference is between this project and the USBSerPassThruLine project mentioned above as far as HID functionality goes.

I'm thinking either:

  1. The NicoHood HID project came out later and/or user gdsports was not aware of it. -or-
  2. The NicoHood HID project achieves some kind of pseudo-HID functionality while retaining the same "composite descriptors"

Created a forum posts over on the arduino forums asking these questions: https://forum.arduino.cc/index.php?topic=728721.msg4901811#msg4901811

...and I was almost immediately banned from the forum even though I specifically mentioned "if this post is too 'promotional' please let me know and I will amend it"

F***.
