Dear Maintainer,

I don't remember exactly when bluetooth had broken, probably this year
spring or even earlier.

Logs of bluetooth.service when the dongle is plugged:

No new log entries appear when I try to send some file via
bluetooth-sendto, or blueman-sendto: they just hang at start and then
show an error on timeout. Trying to connect via blueman-manager also
fails on timeout with "input/output error".

Tried to send to several phones, all are paired with the dongle and
trusted. The same dongle works well on a Windows XP system, so this is
not a hardware issue.
