From c80e5ffac0579499ca28444155118ffcdd9b8d7e Mon Sep 17 00:00:00 2001 From: Pavel Troller Date: Mon, 29 Oct 2007 11:13:46 +0100 Subject: HID: Implement horizontal wheel handling for A4 Tech X5-005D This mouse distinguishes horizontal wheel from vertical by a special "pseudo event" GenericDesktop.00b8, with values of 0 for vertical and 8 for horizontal wheel. Because this event is supplied by the parser too late, we need to delay a wheel event, wait for this one and send either REL_WHEEL or REL_HWHEEL to input depending on the event value.
