Hi Fedora kernel team,
today I've received a CP2112 based USB-to-I2C adapter board to interact with some I2C devices. I've chosen an adpater based on that chip since it has a mainline Linux driver.
To my surprise the adapter was not working, because the config file of the Fedora kernel has HID_CP2112 not set (I've checked /boot/config-4.13.16-302.fc27.x86_64).
Recompiling a kernel is not an issue for me, but doing that regularly might get a bit cumbersome at some point.
Therefore I'd like to ask if there is a specific reason why this kernel config option is not enabled in the Fedora kernel and what would be necessary to get this enabled by default?
Thanks, Christoph

Probably because no one has requested it to date, I'll enable it in 4.14+ in F-27+ and it should land back into F-26 once it gets 4.14

That's what I was hoping for.
Thanks a lot, Christoph
