This is the dkms kernel module which I use currently use. Please no fame for me, its the work of genius AceLan Kao. I'm just sharing it. If you build and insert this, bluetooth should work fine. (As long as you use a kernel which includes the device ids of your bt card)
If you need further instructions read this: tar xf xhci-quirk-dkms.tar sudo apt-get install linux-headers-`uname -r` (only if the headers aren't installed already) cd xhci-quirk-dkms make sudo insmod ./xhci-quirk.ko Now check bluetooth, if everything works fine you can make it a dkms module: make clean cd .. sudo cp -a xhci-quirk-dkms /usr/src/xhci-quirk-1.0 sudo apt-get install dkms sudo dkms add -m xhci-quirk -v 1.0 sudo dkms install -m xhci-quirk -v 1.0 dkms status (should show the module as installed) nano /etc/modules (and add xhci-quirk) ** Attachment added: "xhci-quirk-dkms.tar" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1237296/+attachment/3981566/+files/xhci-quirk-dkms.tar -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1237296 Title: 168c:0036 [Acer Aspire E1-572] ath9k QCA9565/AR9565/QCWB335 Bluetooth works sporadic To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1237296/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
