I am trying to setup a Compro U680F USB DVB-T adaptor in Ubuntu 12.04 (kernel 3.2.0-29-generic).

The compro device ID is given (lsusb) as 185b:0680. The following page suggests this device is supported by the RT2832U driver: http://www.dfragos.me/2011/11/installation-of-the-rt2832u-driver-in-linux/

I successfully built the v4l-dvb package from source following this how to, using the "Basic Approach": http://linuxtv.org/wiki/index.php/How_to_Obtain,_Build_and_Install_V4L-DVB_Device_Drivers

After restarting the system the device does not appear to be working. The output from "lsmod | grep dvb" is as follows:

root@DCTbox:/home/dct# lsmod | grep dvb 
dvb_usb               32369   0
dvb_core              110590  1 dvb_usb 
rc_core               26343   1 dvb_usb

If I unplug the device and plug back in, I get the following from "dmesg | tail":

root@DCTbox:/home/dct# dmesg | tail -n 27

If I attempt to load the driver manually I get the following error message:

FATAL: Error inserting dvb_usb_rtl2832u
(/lib/modules/3.2.0-29-generic/kernel/drivers/media/dvb/dvb-usb/dvb-usb-rtl2832u.ko):
Invalid argument

Any advice on how to get this device working successfully would be greatly appreciated.

Kind regards, Marc

1 Answer 1

Try either:

ambrosa / DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0

tmair / DVB-Realtek-RTL2832U-2.2.2-10tuner-mod_kernel-3.0.0

I have a Terratec Cinergy TStick+ (ID 0ccd:00d7).

Neither of these worked for me, and I instead had to use media build driver.

However, your device may work ..

Many thanks for the suggestion. Unfortunately in the end I replaced the tuner with one with better support so am unable to test. –  MarcF Feb 6 '13 at 9:35
