Bluetooth: btusb: Reclassify Qualcomm WCN6855 debug packets 2025-12-01T21:00:07+00:00 Pascal Giard evilynux@gmail.com 2025-10-07T15:33:15+00:00 0b00bee940cb16bfd42e764465705dbf2a95b55c Some Qualcomm Bluetooth controllers, e.g., QCNFA765 with WCN6855 chip, send debug packets as ACL frames with header 0x2EDC. The kernel misinterprets these as malformed ACL packets, causing repeated errors: Bluetooth: hci0: ACL packet for unknown connection handle 3804 This can occur hundreds of times per minute, greatly cluttering logs. On my computer, I am observing approximately 7 messages per second when streaming audio to a speaker. For Qualcomm controllers exchanging over UART, hci_qca.c already filters out these debug packets. This patch is for controllers not going through UART, but USB. This patch uses the classify_pkt_type callback to reclassify the packets with handle 0x2EDC as HCI_DIAG_PKT before they reach the HCI layer. This change is only applied to Qualcomm devices marked as BTUSB_QCA_WCN6855.
