[Bluez-users] Link encryption failed: Input/output error (Belkin F8T013)

Hello folks,

I have a Sony Ericsson K800i phone, which I use as a remote control for my
Linux media center, using a bluetooth 1.1 CSR dongle.

But using a Belkin F8T013, a Bluetooth 2.0 USB dongle, the phone can't
connect to any computer running Linux, neither in an Pentium 4 running
Ubuntu 07.10 nor a PowerPC G4 running Ubuntu 08.04. I get the following
output on the console:

hcid[7355]: link_key_request (sba=00:0A:3A:6E:0A:C7, dba=00:1D:28:2D:39:33)
input[7358]: Incoming connection on PSM 17
input[7358]: Incoming connection on PSM 19
hcid[7355]: /org/bluez: org.bluez.Database.RequestAuthorization()
input[7358]: Link encryption failed: Input/output error (5)

If I strace the input daemon, I get the following output:

events=POLLIN}], 3, -1) = 1

close(8)                                = 0

The interesting part is this line:

read(10, "\4\10\4$\v\0\0", 260)         = 7

$ (0x24) is the error code; LMP PDU Not Allowed.

I can use this dongle in Windows without problem. Does anyone know how to
spy Windows? Any other idea?

Thanks.
