BugLink: https://bugs.launchpad.net/bugs/2081796 [Impact] A new Qualcomm WCN7851 variant is not currently supported. [Fix] Proposed fix: https://lore.kernel.org/linux-bluetooth/20240920-btusb_add_id-v1-1-8c488ccf83ae@quicinc.com/T/#u [Test Case] dmesg output at boot: ``` Bluetooth: hci0: using rampatch file: qca/rampatch_usb_00190200.bin Bluetooth: hci0: QCA: patch rome 0x190200 build 0x5656, firmware rome 0x190200 build 0x43fb Bluetooth: hci0: using NVM file: qca/nvm_usb_00190200.bin Bluetooth: hci0: HCI Enhanced Setup Synchronous Connection command is advertised, but not supported. ``` ``` $ btmgmt info Index list with 1 item hci0: Primary controller addr AA:BB:CC:DD:EE:FF version 12 manufacturer 29 class 0x6c0104 supported settings: powered connectable fast-connectable discoverable bondable link-security ssp br/edr le advertising secure-conn debug-keys privacy configuration static-addr phy-configuration wide-band-speech cis-central cis-peripheral current settings: powered ssp br/edr le secure-conn cis-central cis-peripheral name localhost short name hci0: Configuration options supported options: public-address missing options: ``` [Where problems could occur] The dmesg has: ``` Bluetooth: hci0: Bad flag given (0x1) vs supported (0x0) Bluetooth: hci0: Bad flag given (0x1) vs supported (0x0) ``` That's HCI_CONN_FLAG_REMOTE_WAKEUP, which is set when the device supports waking up. So somehow the driver code conflicts with the flags returned from the device firmware, meaning there might be still something wrong even we have the right driver being loaded. It's unrelated to this patch and is still being sorting out separately. [Other Info] Nominate for linux/oracular, linux-oem-6.11/noble, linux-unstable only.
