What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/isku/roccatisku<minor>/actual_profile
Date: June 2011
Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
Description: The integer value of this attribute ranges from 0-4.
When read, this attribute returns the number of the actual
profile. This value is persistent, so its equivalent to the
profile that's active when the device is powered on next time.
When written, this file sets the number of the startup profile
and the device activates this profile immediately.
