Subject: [Bluez-users] Lost connections - mouse and keyboard

Greetings -

I have a Logitech mouse and keyboard that use bluetooth (dinovo). I
have enabled bluetooth on this Fedora 8 system and both work well with
two problems.

(1) When I lock the system and return later the mouse no longer works.
I have to open a terminal window and issue an hidd --connect command.

(2) When I log out, both the mouse and keyboard stop working. I have to
connect a USB mouse and USB keyboard to enter the authentication
information. Once logged in the bluetooth devices usually work,
although I sometimes have to issue an hidd --connect command to enable
the keyboard.

Any suggestions on resolving these issues would be appreciated.

Thank you,

Brad

It has been on my todo list to convert that WARN_ON() to something that
won't scare users that much, especially the stacktrace shouldn't certainly
be there. I will do it.

Is this behaviour the normal one? IMHO, userspace program should not
cause kernel warnings like this no mater what input from users.

Absolutely.

This particular warning means, that someone (usually indeed hid2hci)
passed usage through hiddev that was out of bounds, with respect to the
device's report descriptor.

This usually means that hid2hci has chosen the wrong method to switch the
modes. Unfortunately, it's not easy to implement always the switching
properly, if we don't know the vendor-specific packet that has to be sent.

in case you have a HID proxy dongle the usbhid driver can be involved.
And since this is hiddev, then it will be caused by the hid2hci program.

Does bluetooth input devices have something to do with usbhid? I don't
know, perhaps this is another problem in kernel.

Please dont mind to add lkml as cc.

Thank you for the reply Marvel. I use the gnome bluetooth client which
apparently does manage bluetooth devices using bluetooth-input-service.
I still have the problem of the devices disappearing if idle for too
long such as when i lock the desktop or log out for a long period.
Sometimes I can re-enable the devices, but sometimes I cannot. This is
frustrating.

I see a the following several times in the system log if i restart
bluetooth:

not using hidd and using bluetoothd-input-service instead is one thing.
For input devices to re-connect you have to have a daemon running that
handles this. The input service is the best way to achieve this. Check
the BlueZ wiki for details.
