I just made some research. First, I download and compiled in kernel module new drivers with some debug info — https://github.com/vhallac/rtbth/ Then, when I tried create pair with another BT device (phone, for example), I got some debug information in syslog:
=== hci0: Cancel Pair Device (0x001a) failed: Invalid Parameters (0x0d) === May be useful: https://github.com/torvalds/linux/blob/164c09978cebebd8b5fc198e9243777dbaecdfa0/net/bluetooth/mgmt.c#L2955 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1189721 Title: Ralink RT3290 needs bluetooth driver To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1189721/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
