Resending message. Is the list broken?

But what could be the mistake, which allowed me to create a device

driver parameters that have to be present, so the kernel side emulation
gets active?
After searching through the kernel source, I've found some more
information. Event emulation is done here:
https://github.com/torvalds/linux/blob/master/drivers/input/ff-memless.c
And this is not triggered by the uinput kernel driver at all.
Would it be possible to add this feature to uinput?
Let's say: If only "FF_RUMBLE" is set and the device reports to be only
able to handle one ff event, then initialize ff-memless.
I could try to create a patch for that, but it would be nice if someone
of the "linux input pros" could at least tell what they think about
this? Is this possible at all or is there anything which would make this
fail?
Thanks in advance.
Best regards
Manuel
