By running a test on all the traces of the devices I have, I noticed that the class MT_CLS_ALWAYS_TRUE could handle all the devices I've seen so far without any other quirks. I guess this is the behavior Win 7 requires in its driver. We can change the default class then and keep the existing classes for backward compatibility and performances for some of them. Two operations have been done: - replaced MT_CLS_DEFAULT by MT_CLS_NSMU - then replaced MT_CLS_ALWAYS_TRUE by MT_CLS_DEFAULT Signed-off-by: Benjamin Tissoires <benjamin.tissoires@xxxxxxxxx> --- drivers/hid/hid-multitouch.c | 53 ++++++++++++++++++++++---------------------- 1 file changed, 27 insertions(+), 26 deletions(-) diff --git a/drivers/hid/hid-multitouch.c b/drivers/hid/hid-multitouch.c index e3f0bf7..25b1d2c 100644 --- a/drivers/hid/hid-multitouch.c +++ b/drivers/hid/hid-multitouch.c @@ -117,7 +117,7 @@ struct mt_device { #define MT_CLS_DUAL_INRANGE_CONTACTID 0x0006 #define MT_CLS_DUAL_INRANGE_CONTACTNUMBER 0x0007 #define MT_CLS_INRANGE_CONTACTNUMBER 0x0009 -#define MT_CLS_ALWAYS_TRUE 0x000a +#define MT_CLS_NSMU 0x000a #define MT_CLS_CONTACT_ID 0x0011 #define MT_CLS_MINUS_ONE 0x0012 #define MT_CLS_DUAL_CONTACT_ID 0x0013 @@ -155,6 +155,9 @@ static int cypress_compute_slot(struct mt_device *td) static struct mt_class mt_classes[] = { { .name = MT_CLS_DEFAULT, + .quirks = MT_QUIRK_ALWAYS_VALID | + MT_QUIRK_CONTACT_CNT_ACCURATE }, + { .name = MT_CLS_NSMU, .quirks = MT_QUIRK_NOT_SEEN_MEANS_UP }, { .name = MT_CLS_SERIAL, .quirks = MT_QUIRK_ALWAYS_VALID}, @@ -177,9 +180,7 @@ static struct mt_class mt_classes[] = { { .name = MT_CLS_INRANGE_CONTACTNUMBER, .quirks = MT_QUIRK_VALID_IS_INRANGE | MT_QUIRK_SLOT_IS_CONTACTNUMBER }, -
