usb_usb: 2.4G Dongle Chilkey ND75

[tmk]

The keyboard dongle doesn't work with the converter. It does not identify itself as a boot keyboard and not even a keyboard in its USB descriptor.

It seems interface 0/1 is boot keyboard/mouse compatible but it does not assert 'Boot Interface' in bInterfaceSubClass, nor keyboard/mouse in bInterfaceProtocol.

Hi Hasu, thanks again for looking into this issue.

I've compiled a hex from scratch but was having some issues with it, so did some digging and I think that the vendor and product IDs in hidboot.h are slightly wrong.

I've changed it like so, and it's now working for me:

diff --git a/hidboot.h b/hidboot.h

I've been using the 2.4G dongle & usb-usb converter most of the day today... When it recognised, it works just as well as the usb cable connection; all my layers etc work fine.

However:

• It isn't always recognised correctly: most of the time, if the keyboard is already in wireless-mode and paired, it will work as long as the dongle and converter are plugged in (while attached together) and then waiting a couple of seconds before touching a key.
• If the keyboard isn't connected properly, either no key presses work or the first key press will get stuck on repeat.
• If the keyboard goes to sleep, then the connection is lost and the dongle/converter needs to be unplugged and plugged back in.

I think the issue with key presses sometimes working and sometimes not is the reason I didn't think your first changes worked initially, in the forum thread.

Anyway, thank you again for your software and time!

[tmk]

Thanks for the patch. The code was updated in repo. I used wrong vid/pid for no reason...

Those issues don't happen when connecting it as usb wired keyboard with the converter, right?

With debug firmware you can see useful info in debug log, perhaps. It is very difficult to debug issues on sleep/wake because logging doesn't work firmly during wakeup.

You can build debug firmware with make -f Makefile.debug or just download it here. https://github.com/tmk/tmk_keyboard/blob/master/converter/usb_usb/binary/usb_usb_debug.hex

Thanks - yes you are correct, there are no issues at all using the usb converter and wired connection to the ND75.

I'll try to capture some info on the sleep/wake wireless issue and post it here.

Unfortunately there's no output at all when the keyboard falls asleep or wakes.

Sorry for late reply.

Which OS are you using?

I guess that power saving code causes the problem. Can you try attached hex file if you have time?

nopowerdown.zip

[timdodge]

No worries at all - I'm using the usb-usb converter wired with no issues at all.

I'm running on Linux: kernel 6.6.52-gentoo. I'll reboot into Win11 later to see how it works there.

I tried the nopowerdown firmware, but it also output nothing when the keyboard fell asleep or woke up:

then no output from the time the keyboard falls asleep

Thanks for testing. No clue on the debug log. I have no idea on debugging further now.
