I found that for pretty much all the input problems, I'd need to do
something like that. Problem is:
- enabling CONFIG_HID_DEBUG requires rebuilding the kernel
- most distributions build hid into the kernel
Wouldn't there be a way to enable the debug at run-time without
impacting too much on performance or binary size?

I'll look at it when I get an occasion to rebuild a kernel (which
thankfully isn't very often these days).
Cheers
