Hi folks,

Before start update the firmware of my dongles I would like make sure
that nothing is wrong. Sometimes, dongles upgrades can end up with
a dead dongle :) I read some documents in the Marcel's home 
page(http://holtmann.org) but I am afraid of upgrade my dongles :)

I have the following dongles/adapters:

>>>> D-Link DBT-120 Hardware B3
$hciconfig -a hci0 version
hci0: Type: USB
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 192:8 SCO MTU: 64:8
HCI Ver: 1.1 (0x1) HCI Rev: 0x1bb LMP Ver: 1.1 (0x1) LMP Subver: 0x1bb
Manufacturer: Cambridge Silicon Radio (10)
$hciconfig -a hci0 revision
hci0: Type: USB
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 192:8 SCO MTU: 64:8
HCI 15.3
Chip version: BlueCore02-External
Max key size: 56 bit
SCO mapping: HCI

>>>> D-Link DBT-122 Hardware A1
$hciconfig -a hci0 version
hci0: Type: USB
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 377:10 SCO MTU: 16:0
HCI Ver: 1.2 (0x2) HCI Rev: 0x0 LMP Ver: 1.2 (0x2) LMP Subver: 0x309
Manufacturer: Broadcom Corporation (15)
$hciconfig -a hci0 revision
hci0: Type: USB
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 377:10 SCO MTU: 16:0
Firmware 0.3 / 9

>>>> IBM T41
$hciconfig -a hci0 version
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 192:8 SCO MTU: 64:8
HCI Ver: 1.1 (0x1) HCI Rev: 0x222 LMP Ver: 1.1 (0x1) LMP Subver: 0x222
Manufacturer: Cambridge Silicon Radio (10)
$hciconfig -a hci0 revision
hci0: Type: USB
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 192:8 SCO MTU: 64:8
Build 546
Chip version: BlueCore02-External
Max key size: 128 bit
SCO mapping: HCI



I am not sure if upgrade will work in the DBT-122 and in my notebook
IBM T41. If someone has tips or references of how do this procedure
please send me the links.


Thanks in advance,
Claudio

try only this dongle. This should work, but others may break.

check with "hciconfig hci0 revision" (as root). It might be ROM based
chip and then you can update it.

yes, I meant you _can't_ update ROM chips.
