My mouse and keyboard sometimes loose their connection. I'm running 2.6.10_rc2 and hidd --server on boot. I also run a script I found around the net that runs hidd --search and/or hidd --connect with retries and delays to try to connect to the keyboard & mouse. When the connection is lost, I typically run "hidd --show" to see that it is indeed not connected then "hidd --search" to reconnect and it USUALLY works especially since I upgraded the kernel from 2.6.8. Thankfully it is usually the mouse that is a problem, so I can do this from the same box. When "hidd --search" fails I remove and replace the batteries. I've noticed the mouse lights blinking at me, which I'm not sure is telling me the batteries are low. I checked and they weren't really that low. It sometimes seems as though the mouse desires batteries really well charged. The few times the keyboard was a problem, I ssh from another box and "hidd --search" and it works.

I'm new to this and I'm a bit confused on some things:

1) when the devices sleep should "hidd --show" show the device? (And the hidd server is waiting for a wakeup from the device?) I guess I should check "hidd --show" sometime when they've been inactive.

2) what does the blinking mouse mean (I don't have any docs with these devices).

3) Should I have to push the mouse and keyboard buttoms on every reboot or just one time for the device? (should I need that second script I'm running?)

first questions is if this is the old Microsoft desktop or new 2.0 version of it?

When the device sniff then the connection should still be shown, but after a while it disconnects and then it will not be shown anymore. However this doesn't matter, because it will reconnect on the next touch to your running "hidd --server" instance.

How should I know? I don't work for Microsoft ;)

You need to push the connect button only for the initial setup and there is no need for another script. Only "hidd --server" must run. However you need to push a keyboard or mouse button to initiate the reconnect.

[Bluez-users] Permissions on Sockets

My application connects to a custom device. The app works when I run as su but I get an error from hci_send_cmd from the writev(dd, iv, ivn) when I run as a regular user.

Are there some permissions that I need to set to allow my regular user to write to the socket?

Thank you,

Jonathan

for some HCI commands you need root rights. About what commands are we talking?

Re: [Bluez-users] Permissions on Sockets

Thank you for your help.

I am doing an inquiry of all devices, finding our device, connecting to it and the reading bytes via a rawsocket.

The only issue I see so far is the writev command (I copied the code from hci_send_cmd).

How do I assign root rights for this?

you need to change the HCI security filter inside the kernel or make your application setuid root or adapt the capabilities of your program.
