I'm not sure of anything, but it has worked for me in the past, and I get
the exact same results if I comment out the auth and encrypt commands in
the hcid.conf file. I've left them commented out for the rest of my
debugging.

I don't think the answer is quite this simple for the following reasons:
1) my hcid.conf file has
security auto;
which if I understand it correctly is supposed to use the
/etc/bluetooth/pin file as opposed to the pin_helper application.
1a) If I change this to "security user" the bluez-pin helper launches (but
my Palm T times out before I can enter the PIN on the laptop!) If I try to
pair the T610 phone with the laptop when "security user" is set, the
bluez-pin helper program DOES NOT LAUNCH, and hcidump -X says the
following:
HCIDump - HCI packet analyzer ver 1.12
device: hci0 snap_len: 1028 filter: 0xffffffff
> HCI Event: Connect Request (0x04) plen 10
B2 E6 1D D9 0A 00 04 02 52 01
< HCI Command: Accept Connection Request (0x01|0x0009) plen 7
B2 E6 1D D9 0A 00 00
> HCI Event: Command Status (0x0f) plen 4
00 01 09 04
> HCI Event: Connect Complete (0x03) plen 11
1A 29 00 B2 E6 1D D9 0A 00 01 00
2) My Palm T pairs correctly with the Pin in the /etc/bluetooth/pin file
when I use "security auto" (but the T610 phone does not).
3) I have pin_helper set to /usr/bin/bluez-pin (which when I run it
manually appears to work just fine...) and when I (successfully) pair my
Palm T, it does not ask me for a pin, but uses the one in the pin file (if
"security auto" is set).
I find it interesting to note that when "security user" is set, although
the bluez-pin program runs, my Palm T fails in the pairing attempt before
I have time to enter a Pin. BUT, under the same conditions, the bluez-pin
tool never launches when my T610 attempts to pair. {This seems to be a
problem with the hcid <-->bluez-pin tool connection?}
When I'm using "security auto" the PalmT pairs just fine with the pin in
the /etc/bluetooth/pin, but the T610 does not.
All of the above tests were done with auth and encrypt turned off.

The only applications I'm running are hcid, sdpd and rfcomm which are
started in my bluetooth services (rc.d) file. I even commented out the
"rfcomm bind all" command from my /etc/rc.d/init.d/bluetooth file, but it
didn't change anything.

The default hcid.conf is quite good and you should only change the name
or class of device.

You will only accept this connection if you become the master of the
piconet.

This mean unsupported remote feature which may lead to that the phone
does not support the role switch. Check with "hcitool info ..." and
report.

And how is the sdpd started? Do you use the -m switch?

you set yourself into security mode 3 by using auth and encrypt. Are you

The PIN helper can't provide a PIN as it seems. Fix this.

Even an application with L2CAP_LM_MASTER set can force the role switch
at connection creation.

this is unsupported remote feature. What says "hciconfig -a" and
"hcitool info <phone-bdaddr>"? Are you forcing the role switch?
