Freecom DVB-T USB

PCanavan · 03-19-2006, 06:40 PM

I'm trying to get a Freecom DVB-T USB to work. From checking on linuxtv, I believe that this should be supported by the dvb_usb_dtt200u kernel driver (URL obfuscation to beat posting rules - host: www linuxtv org page: /wiki/index.php/DVB_USB#WideView.2FYakumo.2FHama.2FTyphoon.2FYuan_Boxes_and_Pens). Currently, however, I'm not having much luck.

The kernel detects the USB device, writing to the system log:
eg:

Code:

Mar 19 23:59:36 ninja usb 1-2: new high speed USB device using ehci_hcd and address 15

It is then correctly identified by lsusb:

Code:

Bus 001 Device 015: ID 14aa:022a AVerMedia (again) or C&E

However, neither /dev/dvb/* nor /dev/dvb* appear, and there are no driver-specific entries in the system log (other people with this hardware seem to have these, from other posts I've seen). The "new high speed USB device" entry appears, and nothing else. If the dvb_usb_dtt200u module is not loaded manually, the kernel does not auto-load it. If it is manually loaded then there is no change in behaviour, except that it appears in the lsmod output. I'm able to use a USB flash drive ('key') and iPod without issue (these were not plugged in whilst trying to get the Freecom unit to work).

I'm fairly sure that this is not a problem with host hardware, since:
a) My main host works with other USB hardware OK
b) I've seen identical symptoms on two quite different boxes (one is my normal system, one I've just purpose-built to run Myth with this tuner - details below).

However, it is worth noting that I believe this is the only high-speed USB (ie true USB2) device I've got. I've covered the basics below, but I'm happy to include any additional info anyone might want, provided I know how to get it. I've not yet managed to test the tuner itself under Windows, to verify that it's working, but it seems more likely that it's a Linux issue than a hardware one, given the symptoms.

Ideas?

2) Athlon64 3200+, ASUS A8N-VM CSM (nForce 430) mobo, 0706 BIOS, Gentoo amd64
You may have heard complaints about this board - and they're at least fair with BIOS < 0706. Before flashing, USB didn't work at all. Testing with my main system seems to have eliminated the mobo as the problem, though.

It's certainly not the Freecom hardware, as far as I can tell. I've now swapped the unit, and had the new unit running with Windows XP and the drivers from the CD. However, the story under linux has not changed: it looks like it's recognised at the USB level, but not by the actual driver.

simonb · 04-16-2006, 02:14 PM

I just got a Freecom USB DVB-T and get all the same output to lsusb and lsmod.

The only thing that is slightly different is what shows up in the log when I plug the device in.

Apr 16 20:01:51 simon pam_console.dev[9196]: Restoring console permissions for /dev/usbdev2.8

I am using PCLinuxOS p9.2 with the 2.16.5 stable kernel from kernel.org. I have enabled all USB-DVB related modules and installed the dvb-usb-wt220u-01.fw firmware into /lib/firmware according to the instructions at linuxtv dot org. (sorry this forum won't let me post links to other sites yet!)

Even if I modprobe dvb_usb_dtt200u manually and try running DVB apps such as Kaffeine and Klear I get no life out of the thing. There is never any /dev/dvb device or directory showing up (PClinux uses udev and is very similar to Mandriva).

Have I missed anything here? Have Freecom maybe changed the chipset? How do I find out?

Thanks & regards,
SimonB

simonb · 04-17-2006, 12:18 PM

OK. I managed to get the thing to light up at least. I can't get any channels yet but that may be because I get lousy TV reception where I am and I don't have an outdoor aerial socket in this room. I will test in the living room in the next few days.

Basically, the problem is that Freecom have gone and changed the chipset. This requires an updated v4L-usb driver and different firmware. More info here...
http://threebit.net/mail-archive/vid.../msg01503.html

I found that to compile the driver you need the full, compiled kernel source tree and you also have to type make config in the kernel source tree before the driver will compile against it. Just press CTRL-C at the first question, by then it has compiled what the v4l driver needs.
