Hi.
I'm trying to install OSMOSdr on a Raspberry Pi.
I'm following this
guide: http://www.hamradioscience.com/raspberry-pi-as-remote-server-for-rtl2832u-s…
After installing I try to test the RTL2832 USB SDR but I have this error:
root@raspberrypi:~/rtl2832/rtl-sdr/build# rtl_test
Found 1 device(s):
0: Generic RTL2832U OEM
Using device 0: Generic RTL2832U OEM
Kernel driver is active, or device is claimed by second instance of librtlsdr.
In the first case, please either detach or blacklist the kernel module
(dvb_usb_rtl28xxu), or enable automatic detaching at compile time.
usb_claim_interface error -6
Failed to open rtlsdr device #0.
This is my lsmod:
