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

>>>> IBM T41
$hciconfig -a hci0 version
BD Address: XX:XX:XX:XX:XX:XX ACL MTU: 192:8 SCO MTU: 64:8

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,
