From 270baef1fafab50410e0e395ec26834de2dcc390 Mon Sep 17 00:00:00 2001 From: Simon Wood Date: Tue, 19 Feb 2013 20:25:10 -0700 Subject: [PATCH] HID: LG: Add support for Logitech Momo Force (Red) Wheel This patch provides a modified report descriptor to split accelerator and brake, and adds the 'NO_GET' flag to prevent it hanging on connection. Note: for convience this patch is against the follow patch which was applied earlier this week. https://patchwork.kernel.org/patch/2153471/ Signed-off-by: Simon Wood Signed-off-by: Jiri Kosina --- drivers/hid/hid-lg.c | 58 +++++++++++++++++++++++++++++++++++++++++++++++++++- 1 file changed, 57 insertions(+), 1 deletion(-) diff --git a/drivers/hid/hid-lg.c b/drivers/hid/hid-lg.c index 6bb7f05..160c489 100644 --- a/drivers/hid/hid-lg.c +++ b/drivers/hid/hid-lg.c @@ -45,6 +45,7 @@ /* Size of the original descriptors of the Driving Force (and Pro) wheels */ #define DF_RDESC_ORIG_SIZE 130 #define DFP_RDESC_ORIG_SIZE 97 +#define MOMO_RDESC_ORIG_SIZE 87 /* Fixed report descriptors for Logitech Driving Force (and Pro) * wheel controllers @@ -169,6 +170,52 @@ static __u8 dfp_rdesc_fixed[] = { 0xC0 /* End Collection */ }; +static __u8 momo_rdesc_fixed[] = { +0x05, 0x01, /* Usage Page (Desktop), */ +0x09, 0x04, /* Usage (Joystik), */ +0xA1, 0x01, /* Collection (Application), */ +0xA1, 0x02, /* Collection (Logical), */ +0x95, 0x01, /* Report Count (1), */ +0x75, 0x0A, /* Report Size (10), */ +0x15, 0x00, /* Logical Minimum (0), */ +0x26, 0xFF, 0x03, /* Logical Maximum (1023), */ +0x35, 0x00, /* Physical Minimum (0), */ +0x46, 0xFF, 0x03, /* Physical Maximum (1023), */ +0x09, 0x30, /* Usage (X), */ +0x81, 0x02, /* Input (Variable), */ +0x95, 0x08, /* Report Count (8), */ +0x75, 0x01, /* Report Size (1), */ +0x25, 0x01, /* Logical Maximum (1), */ +0x45, 0x01, /* Physical Maximum (1), */ +0x05, 0x09, /* Usage Page (Button), */ +0x19, 0x01, /* Usage Minimum (01h), */ +0x29, 0x08, /* Usage Maximum (08h), */ +0x81, 0x02, /* Input (Variable), */ +0x06, 0x00, 0xFF, /* Usage Page (FF00h), */ +0x75, 0x0E, /* Report Size (14), */ +0x95, 0x01, /* Report Count (1), */ +0x26, 0xFF, 0x00, /* Logical Maximum (255), */ +0x46, 0xFF, 0x00, /* Physical Maximum (255), */ +0x09, 0x00, /* Usage (00h), */ +0x81, 0x02, /* Input (Variable), */ +0x05, 0x01, /* Usage Page (Desktop), */ +0x75, 0x08, /* Report Size (8), */ +0x09, 0x31, /* Usage (Y), */ +0x81, 0x02, /* Input (Variable), */ +0x09, 0x32, /* Usage (Z), */ +0x81, 0x02, /* Input (Variable), */ +0x06, 0x00, 0xFF, /* Usage Page (FF00h), */ +0x09, 0x01, /* Usage (01h), */ +0x81, 0x02, /* Input (Variable), */ +0xC0, /* End Collection, */ +0xA1, 0x02, /* Collection (Logical), */ +0x09, 0x02, /* Usage (02h), */ +0x95, 0x07, /* Report Count (7), */ +0x91, 0x02, /* Output (Variable), */ +0xC0, /* End Collection, */ +0xC0 /* End Collection */ +}; + /* * Certain Logitech keyboards send in report #3 keys which are far * above the logical maximum described in descriptor.
