https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D260161 Mark Johnston <markj@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |wulf@freebsd.org --- Comment #2 from Mark Johnston <markj@FreeBSD.org> --- ng_ubt_intel is missing the device ID for this particular adapter. Adding = it "fixes" the problem, but only because ng_ubt_intel then fails to probe the firmware version. It seems that newer devices return firmware version info= in a TLV array, and ng_ubt_intel (and iwmbtfw) doesn't know about it. Dumping the returned TLV: 0000 00 10 04 10 04 40 00 11 04 10 04 40 00 12 04 00 |.....@.....@....| 0010 37 17 00 15 02 13 04 16 02 00 00 17 02 87 80 18 |7...............| 0020 02 32 00 1c 01 01 1d 02 28 13 1e 01 01 1f 04 26 |.2......(......&| 0030 00 00 00 27 01 00 28 01 01 29 01 00 2a 01 01 2b |...'..(..)..*..+| 0040 01 01 2c 01 00 2d 03 01 0a 0e 2e 01 00 2f 01 01 |..,..-......./..| 0050 30 06 20 6f 9c 09 7b f4 31 01 00 00 00 00 |0. o..{.1..... | Image type TLV: 1c 01 01, and apparently a value of 0x01 there means that t= he device is in boot loader mode. I'm not sure how much work it is to extend ng_ubt_intel to support this dev= ice. I'll try adding TLV parsing support and see how it goes. I wonder if ng_ubt_intel should match on all Intel bluetooth devices, other= wise we'll keep having to diagnose the same problem over and over again. --=20 You are receiving this mail because: You are the assignee for the bug.=
