Upgraded from 12.04 and found my Bluetooth adaptor is not being recognised anymore and thus my usual keyboard/mouse won't work. It's a Logitech dongle for use with keyboard/mouse, but I also use it for Android SmartLock and file transfers.
Bluedevil dosn't load, Bluetooth from Settings says it can't find it. Added everything bluez, bluetooth related including Blueman and no luck. lsusb shows the adaptor though.
Ran a few things in Terminal from previous requests on Ubuntu and Kubuntu forums. Can anyone help?
dmesg | grep -i blue
lsusb
hcitool dev
EDIT:
After several days of Google searching, I finally found the solution here:

"There are two modes the dongle works in, Embedded and HCI. By default the embedded is active, which emulates a USB device so it seems to your PC that your using a normal USB mouse/keyoard.
If you hold the little red Button on the USB BT mini-receiver it will enable the other mode. Hold the red button on the BT dongle and plug it into the computer, and after 3-5 seconds of holding the button, the Bluetooth icon will appear in the system tray.
You can then use the adapter as a BT receiver. The adapter continues to work in BT mode after reboots, but I think the occasional BT failure (usually after an update) is caused by the mode changing."
