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 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

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.

My bluetooth device:
Bus 003 Device 103: ID 8087:07dc Intel Corp. Bluetooth wireless
interface
"lsusb -v" shows lots of details, e.g.
Device Descriptor:
bLength 18
bDescriptorType 1
bcdUSB 2.00
bDeviceClass 224 Wireless
bDeviceSubClass 1 Radio Frequency
bDeviceProtocol 1 Bluetooth
bMaxPacketSize0 64
idVendor 0x8087 Intel Corp.
idProduct 0x07dc Bluetooth wireless interface
bcdDevice 0.01
iManufacturer 0
iProduct 0
iSerial 0
bNumConfigurations 1
...
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/tree/intel
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
