KY-BT100 Bluetooth Adapter [...] As you can see, KY-BT100 doesn't work well, here is the blacklist if you want to compare with yours: https://bugs.edge.launchpad.net/ubuntu/+source/linux/+bug/268502?comments=all -- Bluetooth does not work at Acer Aspire 7520 https://bugs.launchpad.net/bugs/284982 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
