Is the Ducky keyboard VIA? KMK? QMK?

Some keyboards are just incompatible with the HID standard. Is there a driver? If so, it’s not HID…

After you disabled nkey rollover, did you power cycle the KVM? Unplug the keyboard from the KVM and unplug the KVM from the wall. Let it sit for several minutes. Then, replug the keyboard and replug the KVM.

Also, some keyboards like Corsair can be booted into “bios mode” to work with HID, but it will disable all of their proprietary software. I’m not sure if Ducky had that kind of thing available.

I’d look into getting a cheap remappable macroboard to plug into the hid port, like this:

IIRC Ducky KBs do not have a flashable ROM in it for VIA/QMK

I am running into this problem now with my Ducky One 3 and have read conflicting information about this specific model being supported via HID.
While I did not even consider that connectivity on the KVM could be a problem when buying the KB, I am not running out of USB3 Ports and would really want to use the it on a HID port (especially since another Ducky KB was reported to work?).

So far I have:

  • disabled NKRO via the dip switch
  • connected the KB in various ways HID->USB3, USB3->HID, with and without powercycling the KVM in between under both Windows and Linux

However, I could not make it even get recognized on a HID port in any constellation.

As far as I can tell, the KB does not require an additional driver (I certainly didn’t need to install anything) and both OS shown only a single USB device (if that’s worth anything).

Is there anything else I can try to either make it work or debug issues on my side?
I read something about checking the data exchanged via USB via wireshark or using Linux commandline tools like usbhid-dump to narrow what’s causing the problem.

Thanks in advance :slight_smile:

What it boils down to is: The KVM is perfectly HID-compliant. If a keyboard does not work there is something proprietary or driver-related (whether it be the firmware, play-n-plug drivers, or downloaded) that violates HID spec. There’s not much we can do about it, unfortunately.

Sorry, yeah I get that.
Just wanted to figure out, if there is a way to tell if my device exhibits HID-compliant behavior (besides the it just not working). Although in the end it probably just boils down to the same result.
Appreciate the reply, than I just may have to find a mouse that I like and is also HID-compliant…

usb3 hubs work fine via the usb3 ports too fwiw. what’s a link to buy the exact thing you have?
