Thanks, dibl.
I knew this command. What makes this USB-sick situation so frustrating to me ist that you may expect all kinds of misfunctions all the time. You have a storing device and can't relay on an easyness of use.
Quite now all filemanagers (thunar, fm, dolphin) still show a 10GB datastick (you are not authorized bla bla...) which since half an hour isn't mounted anymore. I am sure it will go away with the next reboot, closing and reopening does not change the situation. But that's the kind of misfunction I ***expect*** with USB-sticks. I don't expect "it-just-works" anymore, because, I use sticks seldomly (guess why?) for exact the POS experience I have every time.
Now here on my desktop all my sticks are sdc (as long as I use only one at a time) . Then I want to use it to copy something on my notebook. "mount /dev/sdc /media/sdc/" won't work, because here it is and has to /dev/sdb, stupid me? Stupid POS linux which does not provide a means to reliably mount and use a stick by label.
And yes stupid me. I somehow had an ISO on all of my three sticks. File mangers don't reveal this secert, you have to mount them one by one to see what's stored on the stick. Ok, I had to reformat one of the sticks, guess what, gparted currently is broken. Ok, I use cfdisk, it works. I copy connman to my NB, but now have no clue how to configure my wlan with it.
Thanks.
