Retry attempt 1... Connection lost, reconnecting to https://agentn.us.api5.cursor.sh (attempt 2)... Retry attempt 2... **Verdict: YES** — backport to 6.18.y. This is a 2-line USB device ID addition (`0x0bda:0xd923`) to the existing `btusb` driver for Realtek RTL8922AE hardware. It fits the standard stable exception for new device IDs: small, obviously correct, and the prerequisites are already in your tree (RTL8922A support in `btrtl.c`, the 8922AE quirks section in `btusb.c`). Confirmed: neither `0xd922` nor `0xd923` is present in 6.18.44 yet. The patch should apply cleanly by inserting the new entry after the existing `0x8922` line rather than after `0xd922` (which mainline has but this tree doesn't). drivers/bluetooth/btusb.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/bluetooth/btusb.c b/drivers/bluetooth/btusb.c index 38a066cc3404a..502b2984d994a 100644 --- a/drivers/bluetooth/btusb.c +++ b/drivers/bluetooth/btusb.c @@ -604,6 +604,8 @@ static const struct usb_device_id quirks_table[] = { BTUSB_WIDEBAND_SPEECH }, { USB_DEVICE(0x0bda, 0xd922), .driver_info = BTUSB_REALTEK | BTUSB_WIDEBAND_SPEECH }, + { USB_DEVICE(0x0bda, 0xd923), .driver_info = BTUSB_REALTEK | + BTUSB_WIDEBAND_SPEECH }, { USB_DEVICE(0x13d3, 0x3617), .driver_info = BTUSB_REALTEK | BTUSB_WIDEBAND_SPEECH }, { USB_DEVICE(0x13d3, 0x3616), .driver_info = BTUSB_REALTEK | -- 2.53.0
