Perhaps this change deserves an UPDATING entry? Today I upgraded only to find out that my bluetooth related things stopped working. It turned out that ng_ubt didn't attach to my USB bluetooth adapter. Only then I discovered this change, installed the firmware package, etc. As strange as it may seem, previously my adapter worked without uploading any extra firmware. Some data points, just in case: idVendor = 0x0b05 idProduct = 0x190e bcdDevice = 0x0200 iManufacturer = 0x0001 <Realtek> iProduct = 0x0002 <ASUS USB-BT500> rtlbt_is_realtek: found USB Realtek rtlbt_dump_version: hci_version 0x0a rtlbt_dump_version: hci_revision 0x000b rtlbt_dump_version: lmp_version 0x0a rtlbt_dump_version: lmp_subversion 0x8761 main: loading firmware /usr/local/share/rtlbt-firmware/rtl8761bu_fw.bin main: loading config /usr/local/share/rtlbt-firmware/rtl8761bu_config.bin main: Firmware download complete rtlbt_dump_version: hci_version 0x0a rtlbt_dump_version: hci_revision 0xdfc6 rtlbt_dump_version: lmp_version 0x0a rtlbt_dump_version: lmp_subversion 0xd922 main: Firmware download is successful! > Attempt to initialize FreeBSD bluetooth stack while such a device is in > bootloader mode locks the adapter hardly so it requires power on/off > cycle to restore. > > This change blocks ng_ubt attachment unless operational firmware is > loaded thus preventing the lock up. > > Sponsored by: Future Crew LLC > MFC after: 1 month > Differential Revision: https://reviews.freebsd.org/D46738 -- Andriy Gapon
