The device is working properly. Signed-off-by: Zhang Heng Signed-off-by: Jiri Kosina Signed-off-by: Sasha Levin --- **YES** This commit should be backported to stable kernel trees. Here's my extensive analysis: 1. **The commit fixes a real user-visible bug**: The device causes repeated USB interface timeout errors (`usb_set_interface failed (-110)`) that spam the kernel log and potentially interfere with device operation. The error log shows five consecutive timeout failures over 25 seconds, which would significantly impact user experience. 2. **The fix is minimal and contained**: The code changes are extremely simple - just adding two lines to define the vendor/device ID in `hid-ids.h` and one line to add it to the `hid_ignore_list[]` array in `hid-quirks.c`. This is the standard pattern for HID quirks. 3. **Similar commits were backported**: This is very similar to "Similar Commit #1" (Logitech GROUP) which also dealt with HID interfaces on audio devices causing problems. That commit added `HID_QUIRK_NOGET` and was backported. The pattern is identical - an audio device with a problematic HID interface that needs to be handled via quirks. 4. **No risk of regression**: The change only affects devices with vendor ID 0x4c4a and product ID 0x4155. When a device matches this ID, the HID subsystem will simply skip it via the `hid_ignore()` function check in `hid_add_device()`. This cannot affect any other devices. 5. **The device functions properly with the fix**: The commit message explicitly states "The device is working properly" - meaning the audio functionality works fine once the HID interface is ignored. This is not breaking functionality but rather preventing the HID subsystem from interfering with a working audio device. 6. **The error pattern indicates a hardware quirk**: The continuous timeout errors (-110) when trying to set the USB interface suggests the device's HID implementation doesn't properly respond to standard HID commands. This is exactly the type of hardware-specific issue that the HID quirks system was designed to handle. This meets all the criteria for stable backporting: it fixes a bug affecting users, is small and self-contained, has minimal risk, and follows established patterns for similar fixes that were previously backported. drivers/hid/hid-ids.h | 3 +++ drivers/hid/hid-quirks.c | 1 + 2 files changed, 4 insertions(+) diff --git a/drivers/hid/hid-ids.h b/drivers/hid/hid-ids.h index 356916608cc49..3787bd508b616 100644 --- a/drivers/hid/hid-ids.h +++ b/drivers/hid/hid-ids.h @@ -1347,4 +1347,7 @@ #define USB_VENDOR_ID_SIGNOTEC 0x2133 #define USB_DEVICE_ID_SIGNOTEC_VIEWSONIC_PD1011 0x0018 +#define USB_VENDOR_ID_SMARTLINKTECHNOLOGY 0x4c4a +#define USB_DEVICE_ID_SMARTLINKTECHNOLOGY_4155 0x4155 + #endif diff --git a/drivers/hid/hid-quirks.c b/drivers/hid/hid-quirks.c index ff1a9d142cddf..2cf58e3016e7b 100644 --- a/drivers/hid/hid-quirks.c +++ b/drivers/hid/hid-quirks.c @@ -879,6 +879,7 @@ static const struct hid_device_id hid_ignore_list[] = { #endif { HID_USB_DEVICE(USB_VENDOR_ID_YEALINK, USB_DEVICE_ID_YEALINK_P1K_P4K_B2K) }, { HID_USB_DEVICE(USB_VENDOR_ID_QUANTA, USB_DEVICE_ID_QUANTA_HP_5MP_CAMERA_5473) }, + { HID_USB_DEVICE(USB_VENDOR_ID_SMARTLINKTECHNOLOGY, USB_DEVICE_ID_SMARTLINKTECHNOLOGY_4155) }, { } }; -- 2.39.5
