1What: /sys/bus/usb/devices/<busnum>-<devnum>:<config num>.<interface num>/<hid-bus>:<vendor-id>:<product-id>.<num>/isku/roccatisku<minor>/actual_profile
2Date: June 2011
3Contact: Stefan Achatz <erazor_de@users.sourceforge.net>
4Description: The integer value of this attribute ranges from 0-4.
5 When read, this attribute returns the number of the actual
6 profile. This value is persistent, so its equivalent to the
7 profile that's active when the device is powered on next time.
8 When written, this file sets the number of the startup profile
9 and the device activates this profile immediately.
