I'm forwarding this message I recently posted to debian-bugs in order
to see if some of you know how to solve the problem:

Package: bluez-utils
Version: 3.1-3.1
Severity: important

Whenever I try to discover the local system (Debian computer) from a remote
system (mobile device, or other computer) it can't be found. After
some research I found out that the ISCAN mode is disabled:

--------------------------------------------------------------------
# hciconfig hci0
hci0:   Type: USB
        BD Address: 00:0E:6D:3B:31:AE ACL MTU: 192:8 SCO MTU: 64:8
        UP RUNNING PSCAN
        RX bytes:3190 acl:16 sco:0 events:208 errors:0
        TX bytes:1840 acl:17 sco:0 commands:105 errors:0
--------------------------------------------------------------------

But according to my hcid.conf file it should be enabled by default for
all devices, I'm using the prepackaged hcid.conf :

--------------------------------------------------------------------
# cat /etc/bluetooth/hcid.conf
#
# HCI daemon configuration file.
#

# HCId options
options {
        # Automatically initialize new devices
        autoinit yes;

        # Security Manager mode
        #   none - Security manager disabled
        #   auto - Use local PIN for incoming connections
        #   user - Always ask user for a PIN
        #
        security auto;

        # Pairing mode
        #   none  - Pairing disabled
        #   multi - Allow pairing with already paired devices
        #   once  - Pair once and deny successive attempts
        pairing multi;

        # Default PIN code for incoming connections
        passkey "1234";
}

# Default settings for HCI devices
device {
        # Local device name
        #   %d - device id
        #   %h - host name
        name "%h-%d";

        # Local device class
        class 0x3e0100;

        # Default packet type
        #pkt_type DH1,DM1,HV1;

        # Inquiry and Page scan
        pscan enable; iscan enable;

        # Default link mode
        #   none   - no specific policy
        #   accept - always accept incoming connections
        #   master - become master on incoming connections,
        #            deny role switch on outgoing connections
        lm accept;

        # Default link policy
        #   none    - no specific policy
        #   rswitch - allow role switch
        #   hold    - allow hold mode
        #   sniff   - allow sniff mode
        #   park    - allow park mode
        lp rswitch,hold,sniff,park;
}
--------------------------------------------------------------------

In an effort to make the Debian computer visible to other devices
I'm running the following command:

--------------------------------------------------------------------
# hciconfig hci0 piscan
# hciconfig hci0
hci0:   Type: USB
        BD Address: 00:0E:6D:3B:31:AE ACL MTU: 192:8 SCO MTU: 64:8
        UP RUNNING PSCAN ISCAN
        RX bytes:3294 acl:16 sco:0 events:221 errors:0
        TX bytes:1878 acl:17 sco:0 commands:112 errors:0
--------------------------------------------------------------------

But after a while the ISCAN mode gets disabled and I must keep running
hciconfig to make the computer visible again.

I have tried with two USB-BLUETOOTH dongles of different brands
and the problem persists.

I have also tried it in sid and etch with the same results.
