Hi and welcome,
By what isn't your device found, only MythTv? The most important part is if a /dev/dvb/ device exists.
Seeing you mention lsusb, posting the relevant output would help a lot. Check the dmesg output for any possible errors.

Serafean.

Hi,

the command neede to check the existence is "ls" just run
Code:
ls /dev/dvb/*
in a console. But since your device isn't found by anything, I'd guess that it doesn't exist.
Could you post the relevant lsusb output? Google hasn't found anything dvb-related using it9015 as a keyword. Would you mind posting a link to your product?
To explain what I'm trying to do here : I'm trying to get enough information about your device to assert whether it is supported under linux or not. The best case scenario is that there will be a perfect match on this page. If not, an usbid match is usually enough. From that page you can also get information about the kernel version your device became supported in.

your link list noted above shows it as Markings Mini DVB T

the pic certainly matches, maybe i don't have the correct it9137.fw firmware, where can i get it from?

thx keef

Update

I've given up with the ITE DVB-T tuner and since it seems to recognise the YUAN EC300 DVB-T tuner card i ran w-scan
which resulted in going thru all the channels and ending with this

802000: (time: 15:00)
810000: (time: 15:18)
818000: (time: 15:35)
826000: (time: 15:53)
834000: (time: 16:11)
842000: (time: 16:29)
850000: (time: 16:47)
858000: (time: 17:05)

ERROR: Sorry - i couldn't get any working frequency/transponder
Nothing to scan!!


HELP: please - what am i doing wrong

Hi,

First off : make sure which version of the tuner you have; the page specifies that version 2 of the Zolid tuner is only supported since version 3.4; an update might be needed. If you're not sure about the firmware, and in the case you decide for an update, here is a quick guide for it.

For your second tuner : you mentioned you had windows; does it manage to scan something there? Try connecting it to a better antenna.
FYI : specifying which country you are in will shorten the scan period. (w_scan -c <country_code>).

on the Zolid tuner i guess it could be version 2, linux doesn't tell me but i have been back to original packaging which alas also doesn't tell me
i did follow the instructions you mention earlier but the it9137.fw firmware instructions don't work

./get_dvb_firmware it9137
says not recognised so is there anywhere else i can get the firmware from?
can i upgrade to 3.4 with ubuntu i wonder?

TUNER2
swapped aerial and added a booster
tried using w_scan -c GB but it still ends with

834000: (time: 48:34)
834167: (time: 48:52)
833833: (time: 49:16)
842000: (time: 49:45)
842167: (time: 50:23)
841833: (time: 50:42)
850000: (time: 51:06)
850167: (time: 51:25)
849833: (time: 51:43)
858000: (time: 52:01)
858167: (time: 52:19)
857833: (time: 52:37)

Hi,

yes : http://kernel.ubuntu.com/~kernel-ppa/mainline/

Quote:

yes : http://www.ite.com.tw/uploads/firmwa...usb-it9135.zip
The get_dvb_firmware script is only packaged since kernel 3.3, sorry, I missed that part.

the tuner2 not being able to find anything is really weird. Try looking through logs and the module debug info (if you're up to it) to figure out if there is a problem in the driver.
