Comment 4 for bug 318465

Adam: by disconnecting & reconnecting, or uninstalling bluez, you reset the device to work in a legacy compatibility mode (the BIOS & linux wil see it as an USB keyboard & mouse). The result is that you can't use bluetooth for e.g. connecting to your mobile phone.

This sounds like the same bug that people have reported since at least back in 2006 but that gets routinely ignored & then closed by some developers (even after people say it's not fixed yet).

I hope you'll have more luck, and someone will actually look at it this time...
