Bluetooth Broadcom Corp. BCM20702A0 hci_conn_timeout + 0x75 / 0x2a0

J'ai des problèmes avec ma connexion Bluetooth qui diminue constamment. Le chipset est un Broadcom BCM20702A0 (ADAPTATEUR BLUETOOTH USB 2.0 PLUGABLE http://goo.gl/h42upl ) Avant et après le couplage, l'appareil apparaît puis disparaît toutes les 3 secondes. J'ai cependant vérifié à travers de nombreux forums pour trouver une solution.

J'utilise Ubuntu 14.04, les détails des dongles d'erreur et wifi ci-dessous:

(une partie) de la sortie de dmesg | grep blue:

Après quelques tests, j'ai réduit le problème à BlueProximity 1.2.5-6. Une fois supprimé, le problème a été résolu. J'ai également testé sur Ubuntu 15.04 et cela a le même problème lorsque BlueProximity est installé, pour exclure le bogue Kernal.

Ressemble à un bug du noyau (par exemple RedHat bugzilla ), le rapport y dit:

L'erreur signalée par moi au 10/02/2015 s'exécutait sur un noyau 3.17.8-200.fc20.

J'ai ensuite mis à niveau vers 3.18.5-101.fc20 et 3.18.7-100.fc20. En effet, je n'ai plus eu le même bug depuis.

Alors suggérez essayez un noyau plus tard .
