Hi,
I'm not sure if anyone noticed this patch. Did I send it to the right place?
Thanks,
Forest

Hi Jiri,
This patch has gone ignored on the linux-input mailing list. Perhaps that was
done intentionally, but I wanted to try once more to get it looked at before
giving up.
Can you comment?
Thanks,
Forest

Hi,
I have applied the patch as it makes sense per se.
Still, I'd be interested to know what is the device in question actually
sending and what it has in its report descriptor. Does it indeed use 0x00
code? For what reason?
Thanks,

Thanks! I hope your holiday was pleasant.

I wish I could answer that for you. I don't really know much about the device
(I haven't actually seen one myself).
I'll try to request more information from the manufacturer.
Thanks,
Forest
