<p>Hi Marcus,</p>
<p>thanks for your extensive help!! I tried out your suggestions.</p>
<p>I rebooted the raspberry pi many times ;-)<br>

The result is: Bus 001 Device 005: ID 0bda:2838 Realtek Semiconductor Corp. RTL2838 DVB-T
I think this match my rtl-sdr.rules line with "blacklist dvb_usb_rtl28xxu" and "blacklist rtl2838"?

Seems to be normal? Do you see anything suspicious?

<pre wrap="">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

<pre wrap="">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

"I tried many [...] but it doesn't work": so, what exactly you've tried
would be kind of relevant :)
I'll go out on a limb here based on statistics and say: you might have
missed what

<pre wrap="">Hello,
a few days ago I tried to install rtl-sdr on my raspberry pi. I'm
using a dvb-t usb stick with Realtek, RTL2838UHIDIR chipset. I build
the software following the guide in the wiki. I used two additional
switches: cmake ../ -DINSTALL_UDEV_RULES=ON -DDETACH_KERNEL_DRIVER=ON
After installing the software I created a blacklist in cd /etc/modprobe.d:
blacklist dvb_usb_rtl28xxu
blacklist rtl2832
blacklist rtl2830
blacklist rtl2838
After rebooting the device I tried to test rtl-sdr with rtl_test -t
and got this result:
Found 1 device(s):
0: Realtek, RTL2838UHIDIR, SN: 00000001
Using device 0: Generic RTL2832U OEM
usb_claim_interface error -6
Failed to open rtlsdr device #0.
I don't know how to fix this error. I tried many suggestions found via
google but it doesn't work.
Can someone help me to fix this?
Thanks for your help!!
Joachim
