I have done some further tests with this firmware and it does not return
the correct signal lock data. By default the signal lock returns the
last good lock and updated by interrupt. This just means when lock is
lost the driver still returns lock.

I will need to modify the interrupt return.

However, it may be a different tuner.

Ok, i tested it. Device recognized on WinXP with original driver, but tv
application says "no lock".
I'm not sure it worked on WinXP but driver cd is original and
succesfully loaded and recognized.
Again tested on ubuntu with new lmedm04.c and lme2510b_fw.sh than make,
make install, and restart.

It found a LG tuner

remove the dvb-usb-lme2510c-lg.fw firmware file.

rename dvb-usb-lme2510c-s7395.fw to dvb-usb-lme2510c-lg.fw.

I think the id of the chip is faulty or default.

I will test the firmware with LG tuner later.

It is not the LG, s7395 or S0194 tuner.

So the id is intentional. 

How does it identify itself in windows?

I need to find out what exactly the RS2000 tuner is. So currently the
linux driver is not supported with your device.

A little update...

I now have one of these devices. The chip is actually a M8BRS2000 which
is a combi frontend/tuner device.

The ID is confirmed as 3344:22f0, it appears to be patched by the
Windows Driver as 3344:1120 devices try wrongly to use the RS2000
driver.

There is no Linux frontend driver for this device. I will start to write
one shortly, so support could be several months away.

Malcolm

I have written the M8BRS2000 frontend, which has been on test for the
last two weeks.

Unfortunately, on Friday my device has partially failed, in that the
m8brs2000 chip starts to fail with prolonged use.

It seems to be an heat issue as cooling the device restores normal
operation. I will do some more tests in a lab this week for dry-joints.

Have you or anyone else noticed any similar problems running the device
under Windows?

This means the device driver for Linux is back on Alpha and cannot be
released.

Thanks for the info on the correct name and manufacturer.

I have been working on the Linux driver recently.

The problem was due to incorrect register programming and not heat.

However, the now called m88rs2000.ko module still suffers from frequency
drift, that causes loss of lock.

Problems are due to demodulator registers 0x9c,0x9d and tuner registers
0x04,0x06 and the purpose of registers 0x50,0x51.

I hope to have beta patches ready for this shortly.

Malcolm

Hi Malcolm,

first of all, thanks for all your effort making Linux drivers available for the LME2510/LME2510C based devices. I also own one of those with the non-SHARP / non-LG tuner.

I did further digging and found that the chipset used for tuner/demodulation is actually named M88RS2000 (double "8" instead of 8B). I've confirmed that via several google searches as well as looking into my pcb with a magnifier (picture attached). It is manufactured by Montage Tech, with some product info in the links below (nothing too technical, unfortunately):
http://www.montage-tech.com/products_DTV.htm
http://www.montage-tech.com/Product_RS2000.html

I've sent them an email (infosk@montage-tech.com) asking for info that could help us on building a linux driver for their product. Haven't received any reply  yet.

So it seems such model of the DM04 is a combination LME2510C+M88RS2000.

I had mine running under windows for a day or so without failure due to heat. However I could let it run for longer if that would help with troubleshooting the issue you found with your driver. I also offer myself to alpha-test your linux driver in one of my mythtv linux boxes. Just let me know if that could help.

Thanks a lot!
