I've got a Dposh DVB-T USB2.0 (marked ATMT) and I've downloaded some
firmware ( which was v.difficult to find as the page in the wiki is blank)
which put the stick into a "warm" state i.e.
dvb-usb: found a 'Dposh DVB-T USB2.0' in cold state, will try to load a
firmware
dvb-usb: downloading firmware from file 'dvb-usb-dposh-01.fw'
dvb_usb_m920x: probe of 5-1:1.0 failed with error 64
dvb-usb: found a 'Dposh DVB-T USB2.0' in warm state.
dvb-usb: will pass the complete MPEG2 transport stream to the software
demuxer.
dvb-usb: Dposh DVB-T USB2.0 successfully initialized and connected.
usbcore: registered new interface driver dvb_usb_m920x
I've tried Kaffeine and w_scan to no avail, (WinXP gets a signal), I could
do with some advice on a)perhaps new firmware and b)help with how to use
dvbsnoop or similar to divine what is happening with this device as I lack
sufficient knowledge to proceed

There was someone asking this same some time ago. I think it could be
possible that MT352 demodulator is changed to other one and it does not
work due to that. Could you open the stick and check chips?

I got the front end info from dvbsnoop last night & it says its a Zarlink
MT352, but I should try to open the stick anyway to clear up exactly what
chips it uses, although I think its moulded plastics so I'll have to cut it
open. (@work now, will try later)

If dvbsnoop says that there is Zarlink MT352, then there should be.
It should be also seen from the log, try to look your message.log again
to see if there is mention about Zarlink MT352 demodulator / frontend
and Quantek QT1010 tuner.
It could be also possible that tuner is not working.

I've examined the logs, & I can find no mention of a Quantek tuner - your
suggestion of a non-working tuner seems likely, as tuning is what doesn't
seem to work when I run e.g. w_scan - can you make any suggestion as to
where I go from here? I'm more than willing to test new code etc.

OK, then the reason might by tuner. Tuner may be changed to other one or
tuner i2c-address is changed. I doubt whole tuner is changed. Now we
should identify which tuner is used. There is some ways how to do that.
1) Look from Windows driver files
2) Open stick and look chips
3) Take USB-sniffs and try to identify tuner from there

I've opened the stick & there's an MT352 (as expected) but the other chip is
an MT2060 which is the tuner, I think, as I see that there's an 'mt2060'
module in the tuner module directory. Is there some modification I can do to
the code so that it gets picked up by the driver? - I know a bit of C++ app
programming but I'm very new to C driver code, but would like to learn more.
Hopefully I can help some others who have this chipset as well.....

------x--------
I've had a look at the code & have been attempting to add new code to the
M920x driver to cope with the mt2060 tuner module, although all I've got to
go on is the existing code for the qt1010 tuner. I'm not sure of 1 or 2
magic numbers like the i2c address & so on, and my C abilities are fairly
limited, so I haven't managed to compile my new code without errors yet. I
could do with some help ( or even a patch) to be honest

Looks like small changes to m9206 driver is needed. MT2060 tuner needs
IF1, i2c-address and output clock bit (0/1 if I remeber correctly..).
Those can be seen from windows sniffs or by guessing / testing. IF1 is
easy to set default one, 1220, wrong IF1 only decreases performance. If
there is eeprom used then value is normally read from there, otherwose
just set default. clock is easy to test. I don´t know how many i2c-address
are supported by chip, but most probably there is not too many. Hopefully
only 4. You can look from specs or from other drivers what i2c-addresses
are used for mt2060. I think it will take 2-10 test to find correct values
by trial and error method.
I am now on holiday trip, but next week - monday or tuesday I can fix that
driver that if anyone else haven´t done already.
regards
Antti

I'll have a look at it again now you've come up with some hints, but if I
don't get anywhere, it'd be great if you can have a look at it when you
return from holiday.
Thanks mate,

I've tried adding the mt2060 code - it compiles OK & does seem to be nearly
right,the tuner is being recognised, but I think loading the module causes
the I2c bit of the kernel to Oops - would an incorrect i2c address cause
this?
When I get back from work I'll post my code changes & dmesg output if it
helps

DVB: registering frontend 0 (Zarlink MT352 DVB-T)...
m920x_mt2060_tuner_attach
MT2060: successfully identified (IF1 = 1220)
dvb-usb: Dposh(mt2060 tuner) DVB-T USB2.0 successfully initialized and
connected.
so far so good :) , but when I scan with Kaffeine I get this:
Demod init! //this repeated ~ 30 times
mt352_read_register: readreg error (reg=3, ret==-110) //then this block or
mt2060 I2C write failed (len=2) //similar repeated
until end of scan
mt2060 I2C write failed (len=6)
mt2060 I2C read failed
mt2060 I2C read failed
mt2060 I2C read failed
mt2060 I2C read failed
mt2060 I2C read failed
mt2060 I2C read failed
mt2060 I2C read failed
mt2060 I2C read failed
mt2060 I2C read failed
mt2060 I2C read failed
mt352_write() to reg 51 failed (err = -110)!
mt352_write() to reg 5e failed (err = -110)!
Could this just be due to not getting the .i2c_address set in the
'm920x_mt2060_config' struct correct, or is it another dumb error on my
part?
cheers for the help,
Andrew

after trying a different address (0x61) I no longer get all the "Demod
Inits!" & the failed reads, however I still have no result on scanning. I
shall try to find out what's going on with dvbsnoop also maybe try different
i2c addresses.I've attached the my version of m920x.c, so anyone is welcome
to point out any mistakes, as I'm v.new to driver dev.
regards
Andrew

I can report some (limited) success with the m920x driver. It seems to be
trying to tune when I scan, although no locks on any channels, but it may
just be that I've got a poor signal. When trying Kaffeine there is some
fluctuation from the signal & SNR meters, & there is this output in syslog:
Jul 4 23:43:33 toshiba kernel: MT2060: IF1: 1220MHz
Jul 4 23:43:33 toshiba kernel: MT2060: PLL freq=537833kHz
f_lo1=1757750kHz f_lo2=1183750kHz

num2=8064
Jul 4 23:43:33 toshiba kernel: MT2060: PLL [1..5]: 5d 6d 30 f8 93
Jul 4 23:43:34 toshiba kernel: MT2060: IF1: 1220MHz
Jul 4 23:43:34 toshiba kernel: MT2060: PLL freq=537833kHz
f_lo1=1757750kHz f_lo2=1183750kHz
Jul 4 23:43:34 toshiba kernel: MT2060: PLL div1=109 num1=55 div2=73
num2=8064
Jul 4 23:43:34 toshiba kernel: MT2060: PLL [1..5]: 5d 6d 30 f8 93
and so on...
However, the LED still doesn't light (does that indicate a bigger problem
than just the LED?) and I've still to get a video signal. I shall try to
test it on a known good signal, as there are things interfering with my TV
signal right now.
But it looks pretty hopeful - is there anything you can tell me about
maximising the signal etc?
I've attached my version of m920x.c

There is two kind of LEDs in those sticks. One is power LED that lights
all the time when device is powered and the other lock LED that lights
only when demodulator is locked to the valid channel. I assume your
device has lock LED that should light only when device is locked to the
valid channel. Controlling LEDs is sometimes possible by the driver
software and sometimes not at all. Don't care LED before device is not
working.
I think it is better to strong known good signal and test device against
it to see if everything is almost right. After that you can try to find
settings to reach better receiving sensitivity.
regards
Antti

I'm going to try with a better signal this p.m. Thanks for info re:LED
