The option CONFIG_IEEE802154_ATUSB is available in the vanilla kernel since 4.2. I have the matching hardware and it would be great if this option would be enabled. That way I would not have to re-complie my own kernel just for it.
Enabled on f22 and f23. This was already enabled in rawhide. Thanks for the report.
Verified working with 4.2.5-201 Thanks!
