[Bluez-users] Timeout message from kernel

Some newbie bluetooth questions: I'm running the latest bluez-utils on a
2.4.24 uClinx kernel on a Moto ColdFire 5282 processor. It's sort of
working, but having a bit of trouble trying to connect between a brain box
serial dongle on the ColdFire board and a brainbox usb dongle on a pc.
'hcitool info from the pc yields:

[root@Arwen bluetooth]# hcitool info 00:0A:4F:00:13:5F
Requesting information ...
BD Address: 00:0A:4F:00:13:5F
Device Name: BlueZ (0)
LMP Version: 1.1 (0x1) LMP Subversion: 0x175
Manufacturer: Cambridge Silicon Radio (10)
Features: 0xff 0xff 0x0f 0x00 0x00 0x00 0x00 0x00
<3-slot packets> <5-slot packets> <encryption> <slot offset>
<timing accuracy> <role switch> <hold mode> <sniff mode>
<park state> <RSSI> <channel quality> <SCO link>
<HV2 packets> <HV3 packets> <u-law log> <A-law log>
<CVSD> <paging scheme> <power control> <transparent SCO>

so it looks like the ColdFire dongle is alive and responding to the pc. A
'hcitool scan' from the ColdFire board yields:

/> hcitool scan
Scanning ...
bcsp_timed_event: Timeout, retransmitting 1 pkts
bcsp_timed_event: Timeout, retransmitting 1 pkts
bcsp_timed_event: Timeout, retransmitting 1 pkts
00:0A:4F:00:09:5E BlueZ (0)
/>

and hcitool info on the ColdFire board yields:

/> hcitool info 00:0A:4F:00:09:5E
Requesting information ...
bcsp_timed_event: Timeout, retransmitting 1 pkts
Can't create connection: Input/output error
pid 52: failed 256
/>

Anyone have an idea of what the kernel is complaining about? My thoughts are
there might still be some serial port issues on the ColdFire board...
