RTL2832U: kernel module - josh_xbian - 5th Apr, 2015 02:29 AM
Hi guys,
I've bought a DVB-T tuner usb stick: Hamlet XDVBT900BK, and I'm trying to have it working on my Xbian on RPi2.
This is my kernel version:
Terminal
xbian@xbian ~ $ uname -a
Linux xbian 3.18.8+ #1 SMP PREEMPT Thu Mar 5 03:13:36 CET 2015 armv7l GNU/Linux
And this is what I get when I plug it in:
Terminal
xbian@xbian ~ $ dmesg | tail
[ 4459.511956] usb 1-1.5.4: new high-speed USB device number 8 using dwc_otg
[ 4459.601831] usb 1-1.5.4: New USB device found, idVendor=1b80, idProduct=d3a4
[ 4459.601861] usb 1-1.5.4: New USB device strings: Mfr=1, Product=2, SerialNumber=0
[ 4459.601874] usb 1-1.5.4: Product: Rtl2832UDVB
[ 4459.601884] usb 1-1.5.4: Manufacturer: Realtek
Here is the output of lsusb:
Terminal
xbian@xbian ~ $ lsusb

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Bus 001 Device 008: ID 1b80:d3a4 Afatech
Where the tuner should be the last line.
As far as I've understood digging around, proper kernel module should be dvb-usb-rtl28xxu.ko, and I have it under /lib/modules/3.18.8+/kernel/drivers/media/usb/dvb-usb-v2/, but when I plug the tuner in, nothing happens. No kernel module is loaded, and no device is created under /dev.
Any suggestion ?
Thanks in advance

sudo modprobe dvb-rtl28xxu

Thank you.
It seems that something is still missing anyway.
After typing the command as you suggested, the module is actually loaded:
Terminal
xbian@xbian ~ $ sudo modprobe dvb-usb-rtl28xxu
xbian@xbian ~ $ dmesg | tail -n 1
[ 3944.590547] usbcore: registered new interface driver dvb_usb_rtl28xxu
And
Terminal
xbian@xbian ~ $ lsmod

Still, no device is created under /dev and I'm not able to use the tuner.
