Terratec Cinergy T Stick RC issues

Hey all...
Today i bought a cheap DVB-T USB-stick, the Terratec Cinergy T Stick RC, and of course the first thing i did after plugging it in was trying to find an approriate driver for Arch.
A quick search on google directed me to the ubuntuusers-wiki, which redirected me to a posting on a german ubuntu-forum: http://forum.ubuntuusers.de/topic/probl … st-2361396
It basically says that you have to checkout http://linuxtv.org/hg/v4l-dvb, replace some files by the files found in the archive he attached to the post, compile it using make && make install, download the firmware to /lib/firmware and then finally modprobe the module...
I found that a module called dvb-usb-af9015 was already present on my system, so i went ahead and loaded it...
However, my stick is still not working. No new /dev/v4l device is added, xawtv can't find a tv-source and dmesg doesn't tell me anything useful.
Here's what dmesg says when i plug the stick in:

input: NEWMI USB2.0 DVB-T TV Stick as /devices/pci0000:00/0000:00:1a.7/usb1/1-2/1-2:1.1/input/input7
generic-usb 0003:0CCD:0097.0003: input,hidraw0: USB HID v1.01 Keyboard [NEWMI USB2.0 DVB-T TV Stick] on usb-0000:00:1a.7-2/input1

I also noticed that there is a dvb-usb-af9015 entry in yaourt, which seems to be broken.
Is there any difference between the yaourt-dvb-usb-af9015 and the module that comes with the standard-kernel-2.6.34?
Any ideas what i'm doing wrong?

Yes, the in-kernel driver doesn't recognize your stick. The AUR driver adds support for it, but it uses the development version of the DVB drivers. Well, development moved on, the AUR package didn't, so it is probably broken.

Any ideas what i'm doing wrong?

Basically you are just trying to use a piece of very recent hardware which is not supported by Linux. Someone has written support for it, alright (that's what has been posted on the Ubuntu forum page...), but the necessary changes have not made it into the kernel or the v4l-dvb driver yet. So here are your options:
1. Wait until support is added by the v4l-dvb developers
2. Hack the driver yourself. The necessary changes are in the AUR packages or the Ubuntu forum post. You'll "just" have to merge them into the official driver. (You probably do not want to do this...)

Sorry if this is not the answer you are expecting, but that's the problem with (new) hardware and Linux...

Re: Terratec Cinergy T Stick RC issues

I know, this thread is  old, but maybe you are interrested in the fact that kernel 2.6.37 should support this tv stick. I have the same stick with the same problem.

EDIT:

It works with kernel 2.6.37.

Re: Terratec Cinergy T Stick RC issues

I had the same problem

dmesg | grep dvb
dvb-usb: found a 'TerraTec Cinergy T Stick RC' in cold state, will try to load a firmware
dvb-usb: did not find the firmware file. (dvb-usb-af9015.fw) Please see linux/Documentation/dvb/ for more details on firmware-problems. (-2)
dvb_usb_af9015: probe of 2-1.1:1.0 failed with error -2
usbcore: registered new interface driver dvb_usb_af9015

but it's just to install the driver dvb-usb-af9015.fw from yoaurt

yaourt -S dvb-usb-af9015.fw

and voilà

dmesg | grep dvb
dvb-usb: found a 'TerraTec Cinergy T Stick RC' in cold state, will try to load a firmware
dvb-usb: downloading firmware from file 'dvb-usb-af9015.fw'
dvb-usb: found a 'TerraTec Cinergy T Stick RC' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
dvb-usb: schedule remote query interval to 500 msecs.
dvb-usb: TerraTec Cinergy T Stick RC successfully initialized and connected.

I found that me-tv works fine as tv player.

pacman -S me-tv

Re: Terratec Cinergy T Stick RC issues

I have the same usb-stick and I am running 2.6.37-ARCH.

dmesg output:

usb 3-1.5: new high speed USB device using ehci_hcd and address 9

lsmod:

usbcore               139240  7 dvb_usb_af9015,dvb_usb,btusb,usbhid,ehci_hcd,xhci_hcd
i2c_core               19217  4 dvb_usb_af9015,dvb_usb,nvidia,i2c_i801

me-tv tells me that "there are no DVB devices available".

What is missing here?
