From: "Josenivaldo Benito Junior" <jrbenito@xxxxxxxxxxxxx> Devices like Aureal Cy se W-01RN USB_V3.1 and some derived hardware have a bogus HID Report Descriptor. According to that report descriptor, the maximum logical value for key events is 1 and not 101 (101 keys). This quirk fixes this wrong Report Descriptor and is basically the same found in hid-elecom.c. Original driver can be found at: https://gitorious.org/hid-aureal-kernel-module Signed-off-by: Josenivaldo Benito Junior <jrbenito@xxxxxxxxxxxxx> Signed-off-by: Franco Catrin <fcatrin@xxxxxxxxx> --- drivers/hid/Kconfig | 6 +++++ drivers/hid/Makefile | 1 + drivers/hid/hid-aureal.c | 54 ++++++++++++++++++++++++++++++++++++++++++++++ drivers/hid/hid-ids.h | 3 ++ 4 files changed, 64 insertions(+), 0 deletions(-) create mode 100644 drivers/hid/hid-aureal.c diff --git a/drivers/hid/Kconfig b/drivers/hid/Kconfig index 4ecc256..03e2281 100644 --- a/drivers/hid/Kconfig +++ b/drivers/hid/Kconfig @@ -92,6 +92,12 @@ config HID_APPLE Say Y here if you want support for keyboards of Apple iBooks, PowerBooks, MacBooks, MacBook Pros and Apple Aluminum. +config HID_AUREAL + tristate "Aureal" + depends on USB_HID + ---help--- + Support for Aureal Cy se W-01RN Remote Controller and other Aureal derived remotes. + config HID_BELKIN tristate "Belkin Flip KVM and Wireless keyboard" if EXPERT depends on USB_HID diff --git a/drivers/hid/Makefile b/drivers/hid/Makefile index 22f1d16..5363f17 100644 --- a/drivers/hid/Makefile +++ b/drivers/hid/Makefile @@ -36,6 +36,7 @@ endif obj-$(CONFIG_HID_A4TECH) += hid-a4tech.o obj-$(CONFIG_HID_ACRUX) += hid-axff.o obj-$(CONFIG_HID_APPLE) += hid-apple.o +obj-$(CONFIG_HID_AUREAL) += hid-aureal.o obj-$(CONFIG_HID_BELKIN) += hid-belkin.o obj-$(CONFIG_HID_CHERRY) += hid-cherry.o obj-$(CONFIG_HID_CHICONY) += hid-chicony.o diff --git a/drivers/hid/hid-aureal.c b/drivers/hid/hid-aureal.c new file mode 100644 index 0000000..9fb676b --- /dev/null +++ b/drivers/hid/hid-aureal.c @@ -0,0 +1,54 @@ +/* + * HID driver for Aureal Cy se W-01RN USB_V3.1 devices + * + * Copyright (c) 2010 Franco Catrin <fcatrin@xxxxxxxxx> + * Copyright (c) 2010 Ben Cropley <bcropley@xxxxxxxxxxxxxxxx> + * + * Based on HID sunplus driver by + * Copyright (c) 1999 Andreas Gal + * Copyright (c) 2000-2005 Vojtech Pavlik <vojtech@xxxxxxx> + * Copyright (c) 2005 Michael Haboustak <mike-@xxxxxxxxxxxx> for Concept2, Inc + * Copyright (c) 2006-2007 Jiri Kosina + * Copyright (c) 2007 Paul Walmsley + * Copyright (c) 2008 Jiri Slaby + */ +#include <linux/device.h> +#include <linux/hid.h> +#include <linux/module.h> + +#include "hid-ids.h" + +static __u8 *aureal_report_fixup(struct hid_device *hdev, __u8 *rdesc, + unsigned int *rsize) +{ + if (*rsize >= 54 && rdesc[52] == 0x25 && rdesc[53] == 0x01) { + dev_info(&hdev->dev, "fixing Aureal Cy se W-01RN USB_V3.1 report descriptor.
