P.S. Add log_buf_len=3D4M, to grub cmdline for reboot after the other steps. Create a file=20 ``` =3D=3D> /etc/modprobe.d/wifi.conf <=3D=3D options iwlwifi dyndbg=3D"+pmfl" options iwlmvm dyndbg=3D"+pmfl"=20 options btusb dyndbg=3D"+pmfl" options btmtk dyndbg=3D"+pmfl" options btrtl dyndbg=3D"+pmfl" options btintel dyndbg=3D"+pmfl"=20 options bluetooth dyndbg=3D"+pmfl"=20 ``` On Debian run `update-initramfs -k all -u` to include these settings on-boo= t. Many of these do not dymdbg on my system. I'm guessing this line `iwlwifi 0000:04:00.0: Detected RF HR B3, rfid=3D0x1= 0a100` happening early causes the btusb module to be locked out of accessing the device. --=20 You may reply to this email to add a comment.
