hmm, strange: an hour ago adding sudo worked - the upload was
successful and immediately after I tried reuploading as a user and it
also worked. Now neither will work.
I've allready been experiencing this random behaviour before with this
problem, sometimes it will work, most of the time it won't. I still
haven't found any corelation with things like rebooting, other
processes that use USB (and anyway the lsof command should exclude
this, right?) etc.

I do have permissions set ok:

$ ls -lh /dev/ttyUSB0
crw-rw---- 1 root uucp 188, 0 Sep 21 13:53 /dev/ttyUSB0
$ groups renato |grep uucp
adm tty wheel ftp mail http games network video audio optical storage
scanner power users dbus hal pulse-access pulse-rt camera lpadmin uucp
vboxusers input renato
