From: Filipe Laíns <la...@riseup.net> Tested with the G Pro X Superlight. libratbag sees the device, as expected, and input events are passing trough.
https://github.com/libratbag/libratbag/pull/1122 The receiver has a quirk where the moused interface doesn't have a report ID, I am not sure why, perhaps they forgot. All other interfaces have report IDs so I am left scratching my head. Since this driver doesn't have a quirk system, I simply implemented it as a different receiver type, which is true, it just wouldn't be the prefered approach :P Signed-off-by: Filipe Laíns <la...@riseup.net> --- drivers/hid/hid-ids.h | 1 + drivers/hid/hid-logitech-dj.c | 49 +++++++++++++++++++++++++---------- 2 files changed, 37 insertions(+), 13 deletions(-) diff --git a/drivers/hid/hid-ids.h b/drivers/hid/hid-ids.h index 4c5f23640f9c..8eac3c93fa38 100644 --- a/drivers/hid/hid-ids.h +++ b/drivers/hid/hid-ids.h @@ -803,6 +803,7 @@ #define USB_DEVICE_ID_LOGITECH_NANO_RECEIVER_LIGHTSPEED_1 0xc539 #define USB_DEVICE_ID_LOGITECH_NANO_RECEIVER_LIGHTSPEED_1_1 0xc53f #define USB_DEVICE_ID_LOGITECH_NANO_RECEIVER_POWERPLAY 0xc53a +#define USB_DEVICE_ID_LOGITECH_NANO_RECEIVER_LIGHTSPEED_1_2 0xc547 #define USB_DEVICE_ID_SPACETRAVELLER 0xc623 #define USB_DEVICE_ID_SPACENAVIGATOR 0xc626 #define USB_DEVICE_ID_DINOVO_DESKTOP 0xc704 diff --git a/drivers/hid/hid-logitech-dj.c b/drivers/hid/hid-logitech-dj.c index 1401ee2067ca..6596c81947a8 100644 --- a/drivers/hid/hid-logitech-dj.c +++ b/drivers/hid/hid-logitech-dj.c @@ -114,6 +114,7 @@ enum recvr_type { recvr_type_dj, recvr_type_hidpp, recvr_type_gaming_hidpp, + recvr_type_gaming_hidpp_missing_mse_report_id, /* lightspeed receiver missing the mouse report ID */ recvr_type_mouse_only, recvr_type_27mhz, recvr_type_bluetooth, @@ -1360,6 +1361,7 @@ static int logi_dj_ll_parse(struct hid_device *hid) dbg_hid("%s: sending a mouse descriptor, reports_supported: %llx\n", __func__, djdev->reports_supported); if (djdev->dj_receiver_dev->type == recvr_type_gaming_hidpp || + djdev->dj_receiver_dev->type == recvr_type_gaming_hidpp_missing_mse_report_id || djdev->dj_receiver_dev->type == recvr_type_mouse_only) rdcat(rdesc, &rsize, mse_high_res_descriptor, sizeof(mse_high_res_descriptor)); @@ -1605,19 +1607,35 @@ static int logi_dj_raw_event(struct hid_device *hdev, data[0] = data[1]; data[1] = 0; } - /* - * Mouse-only receivers send unnumbered mouse data.
