Hi Joachim,
absolutely no stupid questions involved!
So, ok, assuming you rebooted or ran "sudo udevadm control --reload" and
re-plugged the device, we have to rule out:
* the dvb-t kernel module still being loaded: plug in stick, run
"lsmod|grep rtl", look for suspicious lines
* the stick not having standard USB ids: plug in stick. run "lsusb".
find line describing stick VID:PID. do these match any line in
rtl-sdr.rules?
* some other kernel shenanigans. Run "dmesg -w" to watch dmesg, plug in
stick, see whether suspicious stuff happens to the kernel :)
Best regards,
Marcus

Hi Marcus,
thanks for your reply. To install the udev-rules I used
sudo cp ./rtl-sdr/rtl-sdr.rules /etc/udev/rules.d/
The suggested way
sudo make install-udev-rules
doesn't worked for me (Error: make: *** No rule to make target
'install-udev-rules'. Schluss.).
Or is this the wrong way?
Sorry for this stupid question but I'm a little bit lost...
Best regards
Joachim
