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: окт 02 14:00:36 localhost.localdomain bluetoothd[26088]: RFCOMM server failed for Message Notification: rfcomm_bind: Address already in use (98) окт 02 14:00:36 localhost.localdomain bluetoothd[26088]: RFCOMM server failed for Message Access: rfcomm_bind: Address already in use (98) окт 02 14:00:36 localhost.localdomain bluetoothd[26088]: RFCOMM server failed for Phone Book Access: rfcomm_bind: Address already in use (98) окт 02 14:00:36 localhost.localdomain bluetoothd[26088]: RFCOMM server failed for Synchronization: rfcomm_bind: Address already in use (98) окт 02 14:00:36 localhost.localdomain bluetoothd[26088]: RFCOMM server failed for File Transfer: rfcomm_bind: Address already in use (98) окт 02 14:00:36 localhost.localdomain bluetoothd[26088]: RFCOMM server failed for Object Push: rfcomm_bind: Address already in use (98) окт 02 14:00:38 localhost.localdomain bluetoothd[26088]: Endpoint registered: sender=:1.502152 path=/MediaEndpoint/A2DPSource окт 02 14:00:38 localhost.localdomain bluetoothd[26088]: Endpoint registered: sender=:1.502152 path=/MediaEndpoint/A2DPSink 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.
