kbdtest2 stalls on non-LED keyboard

Open peterhoeg opened this issue 4 years ago • 8 comments

kbdtest2 hangs when trying to program a non-LED keyboard presumably because it is trying to do something with the lights.

Sending this file with kbdtest2 -v file.yaml makes kbdtest2 hang at the first "RECEIVING PACKET".

If I invoke it with -n so nothing is actually sent, you will see that the first part after "RECEIVING PACKET" is Sending light program DONE which leads me to assume it's trying to do something with lighting which is what makes it hang.

This is the output when invoked with -n:

Hi Peter, thanks for reporting. Huh, that is interesting. I'm unaware of how to distinguish led from non-led keyboards programmatically, so there may need to be a configuration setting to handle it. Or perhaps a timer that expires and treats the keyboard as non-led after that.

The first thing you can do is lsusb -vd . If you just do lsusb, you should be able to see the keyboard device name and then rerun with -v for the detail. With luck, there will be some difference between what you get for non-led keyboard and what I get from an led keyboard. If so, I can tweak the driver to avoid sending lighting commands.

Does the windows driver offer you led programming even though the keyboard doesn't support it?

jlquinn avatar Jun 16 '20 21:06 jlquinn

so there may need to be a configuration setting to handle it

The simplest solutions to me is a flag you pass along to kbdtest2 that tells it to ignore the lighting. The timer option if you cannot dynamically detect it sounds very nice of course as it means it'll "just work".

Does the windows driver offer you led programming even though the keyboard doesn't support it?

It does not.

Anything else I can help provide @jlquinn ?

Unfortunately I don't see anything in the lsusb output that distinguishes the two keyboards.

Likely it will require setting up windows in a vm and recording the USB packets back and forth for your keyboard while using the windows driver. That's how I got as far as I did.

It sounds like there must be some difference between the early packets your keyboard sends and mine does. I'll have to take a closer look at the packets and see if I can see anything.

I won't be able to touch it for a week or so. If you're ambitious you can try to set up USB packet recording yourself.

The next step will be to look at the basic messages coming back from your keyboard vs mine. I'm putting this as a placeholder so that I remember when I come back to this.

I'll dump the traffic next weekend.

Haven't had time, sorry.
