Debian system is on a net-book, an Acer Aspire One ZG5
(8G HD, 512MB ram, 1.6GHz Intel Atom CPU). I've choosen
that distro instead of Slackware because its netinstall
make easier to build up a minimal system... and atp-get
do the rest.

Do you think that netbook coul be the matter?
How could I exclude a issue related to USB limited
power?

I have also an usb-2.0 hub with its own power supply, I
could try to plug it and then insert my olicard in this
powered hub... Do you think could this perhaps help to
give more power to our internet key?

An other test could be by installing Debian on my main
PC (that now hosts a dualboot Windows/Slackware). But
I just don't have a free partition on HD... I should
repartition it shrinking actual ones: it is alwasy a
'dangerous' procedure.

Have you got any other ideas to find where the issue
could be?
