Dry Studio Black Diamond 75 keyboard not working

[infosecconsultant]

I thought I'd try with a few other keyboard I have. Unfortunately the Dry Studio Black Diamond 75 keyboard does not register with the deskhop at all.
I'm guessing it's got issues with the power draw but I'm not sure. I don't currently have a way to measure that but I've ordered a little inline USB power monitor/tester.
I turned off the LEDs etc but still no luck.
If there's any advice on debugging please let me know and I'll give it a shot.

Try dumping the usb hid report first, maybe it's also detected as a mouse ... I had to google this keyboard out of curiosity and must admit I have never seen anything like this :) it's pretty interesting...

[infosecconsultant]

I'll try to do that when I'm back tomorrow.
This output?

lsusb -v

The keyboard supports Bluetooth... Is there any chance the raspi could pair a bluetooth keyboard? Or have a bluetooth dongle attached to it?

[hrvach]

Unless a BT dongle presents as a usb keyboard, I doubt that would work, but I was working on pico W BT support, mostly in the other direction (use BT as client so you need only one pico).

Trying to do support for non-boot keyboards as well, that should sort out most issues with a few stubborn keyboard models.

[hrvach]

Any change with the latest fw?

[infosecconsultant]

Hey hrvach, I've got some other firmware issues with that keyboard unfortunately. I'll have to try again once the RMA'd unit comes though in a couple of weeks. Sorry :(

[infosecconsultant]

Hey @hrvach

Still no luck with the keyboard. Not registering any keypresses at all and I've updated to the most recent release of firmware.

The following output is from a linux machine plugged into the 'A' port of the deskhop.

I'm not sure why the device is an 'Apple' device... Bit odd. I'm testing on a mac and a debian based HP at the moment.

Please let me know if you need anything further from my end.

Your keyboard is NKRO, that's not supported yet.. it should work in boot mode though, but I suspect it's also a mouse. Can you try rebuilding with ENFORCE_PORTS set to 1 in user_config.h ?

Ordered a NKRO keyboard, that should help with implementing support for it. 😃

@infosecconsultant is there a change with the latest experimental BETA (https://github.com/hrvach/deskhop/releases/tag/v0.60) ?
