https://bugzilla.novell.com/show_bug.cgi?id=738520 https://bugzilla.novell.com/show_bug.cgi?id=738520#c0 Summary: Using bluez to disable Bluetooth USB device leaves it unusable Classification: openSUSE Product: openSUSE 12.1 Version: Final Platform: x86-64 OS/Version: SuSE Other Status: NEW Severity: Critical Priority: P5 - None Component: Kernel AssignedTo: kernel-maintainers@forge.provo.novell.com ReportedBy: sourtooth@gmail.com QAContact: qa@suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (X11; Linux x86_64; rv:8.0) Gecko/20100101 Firefox/8.0 On my system, with a ASUSTek Computer, Inc. BT-253 Bluetooth Adapter, if I use Bluedevil (part of KDE 4 Workspace) to disable my Bluetooth adapter it is not possible to re-enable it. Further, it is not possible to clear this invalid state other than by taking the following steps, as root: 1) Kill bluetoothd 2) Remove all files/folders under /var/lib/bluetooth 3) Reboot the system, then enter the BIOS configuration 4) Disable the Bluetooth device using BIOS I/O Security features 5) Boot into openSUSE 6) Reboot the system, entering the BIOS configuration again 7) Enable the Bluetooth device at the BIOS level again 8) Boot back into openSUSE - Bluetooth device is now usable again It should be noted that if one does not remove the contents of /var/lib/bluetooth/ then bluetoothd will re-disable the device on startup, leaving it unusable again. It should also be noted that booting into an operating system of any form in between disabling and re-enabling the bluetooth device in the BIOS is crucial, otherwise the steps will have no impact. Symptoms: hcitool dev reports no devices, despite the bluetooth adapter being visible in lsusb and dbus tree of bluetoothd. In some cases, booting the system might fail after the root file system is mounted due to failures to read USB device descriptors from the Bluetooth device. Until the above procedure is performed, all operating systems will not be able to see the Bluetooth device, including Windows 7 which will claim the device is malfunctioning. Reproducible: Always Steps to Reproduce: 1. Disable bluetooth device using Bluedevil Actual Results: Bluetooth device rendered unusable Expected Results: Bluetooth device is merely disabled, and can be re-enabled easily. Rebooting into other operating systems should allow Bluetooth to be functional there as well. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.

I could disable bluetooth without any issues. The newest kernel for openSUSE 12.1 offered by official repo`s is 3.1.9, try upgrading your OS and see if this happens again. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
