Sounds like this might be a kernel bug, or a hardware problem. I am skeptical of CSR Bluetooth dongles since they seem to be consistently unreliable, at least on Linux.
Please try a newer (or older) kernel version and tell us if that makes any difference: https://kernel.ubuntu.com/~kernel-ppa/mainline/?C=M;O=D Or more simply just try live booting Ubuntu 20.04 from USB and tell us if that has the same bug: http://cdimage.ubuntu.com/daily-live/current/ Ubuntu 20.04 is due for release at the end of this week. ** Also affects: linux (Ubuntu) Importance: Undecided Status: New ** Changed in: bluez (Ubuntu) Status: New => Incomplete ** Changed in: linux (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1873718 Title: CSR8510 based BTA-402 Bluetooth device cannot be started To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/bluez/+bug/1873718/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
