Public bug reported:

Hi,

I'm trying to use a Teemi TMSL-50 bluetooth barcode scanner (in keyboard
emulation mode) with a USB bluetooth dongle in an 18.04 machine, which
used to work some months ago.

Now I can still pair them, the ubuntu machine sees the devices and lists
as paired, but can't connect with human interface device service (HID).
/var/log/syslog says

May 26 14:44:49 machine1 bluetoothd[1272]: Can't get HIDP connection info
May 26 14:44:51 machine1 bluetoothd[1272]: connect error: Invalid exchange (52)

Since the scanner and the usb dongle are unchanged, it must be a problem
of the ubuntu machine.

regards
