From: Stefan Achatz Date: Sun, 4 Nov 2012 08:39:04 +0000 (+0100) Subject: HID: roccat: enable Koneplus device reset X-Git-Tag: firefly_0821_release~3680^2~1471^2^5~9 X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=fabe51eb68d450d25b18882988b29626f51592fd;p=firefly-linux-kernel-4.4.55.git HID: roccat: enable Koneplus device reset Device can be reset to factory state by sending a command via info sysfs attr. Added binary attribute info for this purpose, which obsoletes firmware_version attribute.
