[Bluez-users] Epox BT-MS02B Bluetooth HID mouse, authorization and encryption?

["Jouni.Lohikoski@iki.fi" <jlohikos@cc.hut.fi>]

Thanks (marcel) for the page:
[URI1] < http://www.holtmann.org/linux/bluetooth/hid.html >
                                                                                
That gave me courage to buy and try EPoX BT-MS02B mouse. Have to decide
in 14 days if I will keep this.
                                                                                
I got it working, but few things (3) I'd need to find out still. hidd
program seems to be so new, there is no yet any documentation with it.
Maybe later there will FAQ for Linux HID.
                                                                                
I used to have authorization and encryption on in
/etc/bluetooth/hcid.conf before, but I noticed "hidd --search"
wanted a PIN then for outgoing connection. I have no idea what would be the
Bluetooth PIN-code for my mouse, neither was it mentioned anywhere in the
package or in the Windows-documentation which came with the mouse.

I'd still like to have authorization and encryption on, because I have also
Bluetooth OBEX-server on the machine and someone could now easily without
authorization write to my home directory. (gnome-obex-server)

1)
How one turns encryption off just for HID devices, preferrably only for
this one mouse,...or should I somehow be able to get the PID-code for 
my mouse from somewhere? Is the VID:PID column in the table of the first URI
meant for that PID-code information?

2) After 11 minutes 
(I assume from [URI2] <http://www.holtmann.org/linux/bluetooth/epox.html>)
the mouse has disconnected and went to the sleep mode. Is there some
way to reconnect it automaticly? Now I seem to need to push the mysterous
grey button on the bottom of the mouse always, and do `hidd --search` again
to get it reconnected. 

[This 2. one I seem to have solved by upgrading to bluez-utils-2.10, now
hidd --server does accept reconnection after the power saving sleep, but
only if auth+encryption is disabled.]

I need to ask EPoX technical support what exactly is
the little grey button on the bottom of the mouse for. Or would you know?

I don't quite understand what hidd --server is for, [can guess now]
as again, there was no documentation, at least in the rpm packages
(bluez-utils-2.8*rpm) I also looked the newest bluez-utils-2.10 for
hidd documentation, no luck. Is it suppose to accept and re-attach connection
from the HID device which comes out of idle-state?

3)
What is the column "AFH" in the table of the first URI?
(and VID:PID ?)
