Date:		October 2013
Contact:	Stefan Achatz <erazor_de@users.sourceforge.net>
Description:	When written, this file lets one select which data from which
		profile will be	read next. The data has to be 3 bytes long.
		This file is writeonly.

What:		/sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/ryos/roccatryos<minor>/profile
Date:		October 2013
Contact:	Stefan Achatz <erazor_de@users.sourceforge.net>
Description:	The mouse can store 5 profiles which can be switched by the
		press of a button. profile holds index of actual profile.
		This value is persistent, so its value determines the profile
		that's active when the device is powered on next time.
		When written, the device activates the set profile immediately.
		The data has to be 3 bytes long.
		The device will reject invalid data.

Date:		October 2013
Contact:	Stefan Achatz <erazor_de@users.sourceforge.net>
Description:	When written, this file lets one set the default of all keys for
		a specific profile. Profile index is included in written data.
		The data has to be 125 bytes long.
		Before reading this file, control has to be written to select
		which profile to read.

Implementation Notes

This generated page is the file-by-file coverage layer; curated subsystem chapters should link here when they synthesize a multi-file control flow.
Core OS pages should be promoted from atlas-only to deep-reviewed when they explain data structures, invariants, locking, lifecycle, and C implementation snippets.
Driver-family pages are intentionally pattern-oriented unless they are part of the selected PCIe/NVMe representative device path.
