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

Hi Dave,

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:

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

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.

Marcel
