USB DVB-C/T/T2 (Astrometa DVB-T2) not recognized ...

Postby Kresimir » Thu May 12, 2016 5:44 pm

Hello,

I'm trying to get a USB DVB-T stick working on Arch Linux on my Raspberry Pi3.
Posting here because I believe this is an issue related to software (kernel modules).

This USB stick should according to its USB-ID and info at LinuxTV (link1 and link2) consist of the following components:
  • USB interface: Realtek RTL2832P
  • Demodulator: Panasonic MN88472 (2014 revision: MN88473)
  • Tuner: Rafael Micro R828D

Have installed package linuxtv-dvb-apps.

When the device is plugged in, i get the following lines in dmesg ...
$this->bbcode_second_pass_code('', '[ 4148.827438] usb 1-1.4: new high-speed USB device number 5 using dwc_otg
[ 4148.987518] usb 1-1.4: New USB device found, idVendor=15f4, idProduct=0131

[ 4149.060074] usb 1-1.4: Product: dvbt2
[ 4149.079643] usb 1-1.4: Manufacturer: astrometadvbt2')

lsusb gives the following output ...
$this->bbcode_second_pass_code('', 'Bus 001 Device 005: ID 15f4:0131 HanfTek')

lsusb -s 1:5 -v gives this ...

I followed the Arch Wiki DVB-T page but soon recognized that needed kernel modules are not present.
$this->bbcode_second_pass_code('', '# modprobe dvb_usb_rtl28xxu
modprobe: FATAL: Module dvb_usb_rtl28xxu not found in directory /lib/modules/4.4.9-1-ARCH
# modprobe rtl2830
modprobe: FATAL: Module rtl2830 not found in directory /lib/modules/4.4.9-1-ARCH
# modprobe rtl2832
modprobe: FATAL: Module rtl2832 not found in directory /lib/modules/4.4.9-1-ARCH')

From my current position it looks like I need to compile missing modules from scratch.
Am I missing something? Can anybody explain what needs to be done to get those missing modules and any other prerequisites onto my RPi3 and the DVB-T stick working?

Thanks in advance for any idea/hint/trick/reference/...

False alarm!
After system update including Kernel 4.4.9-2 all modules appeared again.
Now the USB device is fully recognized and the dvb-apps are usable.

Seems some of my previous activities, presumably my attempt to compile&install LinuxTV from source, has damaged the original installation based on 4.4.9-1.

Case closed.
