Hi,

hopefully this is the right list (please don't blame me if not :)

It seems it is no more possible to pair with Genius Navigator 900
Pro mouse. It seems it's older mouse probably with no SSP/
built-in PIN.

# bluetoothctl
[bluetooth]# pair ADDR
[CHG] Device ADDR Connected: yes
[CHG] Device ADDR Connected: no
[CHG] Device ADDR Connected: yes
Failed to pair: org.bluez.Error.AuthenticationRejected
[CHG] Device ADDR Connected: no

Hcitool "trick":
# hcitool cc ADDR;hcitool auth ADDR
HCI authentication request failed: Input/output error

The above error is shown before the PIN dialog appears. I also
tried Blueman GUI, but it tracebacks (report also sent).

Moreover:
# hciconfig hci0 sspmode 0
Can't set Simple Pairing mode on hci0: Input/output error (5)

So I cannot try without SSP. It seems there is nothing related
in dmesg.

IIRC the mouse worked in the past.

$ uname -r
4.5.7-200.fc23.x86_64

OS: Fedora 23
userspace: bluez-5.39

machine: Lenovo ThinkPad X240
adapter probably: Intel Centrino 7260 2 x 2 AC+ BT 4.0
module: btintel: Intel Bluetooth firmware file:
intel/ibt-hw-37.7.10-fw-1.80.2.3.d.bseq

Could you advice some other tricks how to get it working?
I could also bisect the problem later

thanks & regards

I wasn't right, the mouse seems to support autopairing and I paired it
without problem under RHEL-7 and it also works there without problem.
I tried to shuffle user-space bluez and there is no change, so it has to be
kernel. I also tried with CSR USB dongle. Regarding the sspmode error,
it's probably not supported by the HW. To sum it up:

kernel-3.10.0-229.el7.x86_64 - it works
kernel-4.5.7-200.fc23.x86_64 - it doesn't work

Try collecting the HCI trace with btmon, btw make sure you have an
agent registered and set as default.

I am going to bisect with vanilla kernel

thanks & regards
