I have a USB Bluetooth adapter (0a12:0001) that has some problems under Trusty. It works about 50% of the time, and if I unplug it and reconnect it, then it works again.
I know this is a known issue. I've read the bug reports. I also know that this is fixed in 14.10 Utopic Unicorn (fixed in kernel 3.14+, Trusty has 3.13), but I can't update to Utopic because Utopic is not an LTS release, and I need an LTS release for what I'm using my computer for.
I don't want to compile and install a newer version of the kernel, as I have failed before and had to reinstall. What I am asking is, how can I fix this without having to compile and install a newer version of Linux or updating to Utopic? (I'm okay with updating my kernel with
apt or something, as long as there is little to no chance of me messing up).
