Hello, the bluetooth problem seems to be caused by USB driver problems. This is the output of "lsusb -t": $ lsusb -t /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/14p, 480M |__ Port 3: Dev 2, If 0, Class=Vendor Specific Class, Driver=, 12M |__ Port 4: Dev 106, If 0, Class=Wireless, Driver=btusb, 12M |__ Port 4: Dev 106, If 1, Class=Wireless, Driver=btusb, 12M |__ Port 6: Dev 7, If 0, Class=Human Interface Device, Driver=usbhid, 12M |__ Port 6: Dev 7, If 1, Class=Human Interface Device, Driver=usbhid, 12M |__ Port 10: Dev 8, If 0, Class=Video, Driver=uvcvideo, 480M |__ Port 10: Dev 8, If 1, Class=Video, Driver=uvcvideo, 480M /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/8p, 480M /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=ehci-pci/2p, 480M |__ Port 1: Dev 2, If 0, Class=Hub, Driver=hub/6p, 480M The address of the bluetooth adapter (here: Dev 106) is changing all the time, as the device cannot be initialized since August, 18th. Does anybody know, what's going on? Kind regards Peter Am 22.08.21 um 21:43 schrieb Peter Nabbefeld via arch-general:
Hello,
after updating my arch installation, bluetooth stopped working. "systemctl status bluetooth" shows the service is active, but when I try to power on or list my bluetooth device using bluetoothctl, no device is found.
Head lines of dmesg output:

but ends with the following lines: can't get device qualifier: Resource temporarily unavailable can't get debug descriptor: Resource temporarily unavailable cannot read device status, No such device (19)
I guess there's sth. broken with the driver (or now driver assigned at all).
When looking into /usr/lib/firmware, I see many if not all updates of August, 18th, and especially many files with pattern "iwlwifi-*.ucode", which might related to my problem.
I already searched the internet, but couldn't find anything useful :-/
However, I found this: https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1591167
While it seems not to be the same, it led me to looking for ibt-*.* and especially to https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/...
I found those files locally in /usr/lib/firmware/intel, same date for latest update as for "iwlwifi-*.ucode", so everything should usually be fine.
How can I check, if the firmware has been installed/loaded properly? How can I find out, which is the correct firmware?
Kind regards Peter
