[Bug 284982] Re: Bluetooth does not work at Acer Aspire 7520

[Jose Hevia]

The problem everybody is having seems a software thing, a lot of people
is having problems with connections.

I think I never had errors on dmesg. I removed the blueman repository
and reverted to standard ubuntu config.

If I put now the usb bluetooth dongle and click setup new
device->Forward the detection of the nintendo wiimote is instantaneus
the problem is connecting, if I click forward:

Pairing wih Nintendo RVL-CNT-01 failed

Looking at dsmesg:

The program lswm detects the device without problems, wmgui gives:
Socket connect error (control channel)

I have used my wiimotes with same hardware with former ubuntu versions,
and it just worked. Something has been broken in the software side.
