Hope he can, he usually reads through FTA section like an Eagle eye.

Any news from QQ? Interesting
example

of firmware integration into a USB Card Windows driver. The example shows that similar DVB World device uses Cypress CY7C68013 USB bridge chipset.

Btw, there is a debug utility called
usbsnoop

that allows to log communication btw an "unknown" or known USB Device and its Windows Driver. It has clear Manual. And there's
explanation

on how to use it with WMWare under Windows to reverse engineer a USB Device Driver, i.e. if you need to extract firmware from it. Do you want to try it? Would be interesting to find out, how this device ID itself, and what happens next...

No reply from either of the LME websites.

That answers my question about the DVBWorld USB DVB-S Chipset.

The DVBWorld Clone even has the same case as the original.

That software is for Windows XP so it may be asking for more trouble to load it into Vista.

What we need here is someone with software experience who can download the .rar file from LME, and look at the code of their driver.

Usbsnoop should work in Vista too. It doesn't install anything apart from placing usbsnoop.sys in Drivers dir to play a role of a buffer btw the device you select in usbsnoop's window and its driver. Its interesting to see the log it will create during the tuner driver installation, as it may hopefully read the tuner's ID, etc., and why Vista rejecting the driver, and then correct its .inf file. Just remember to open Usbsnoop's window to max to avoid blinking.

Window opens with garbage. May be Chinese characters. I'm going to look at the Setup.bat file that installs the driver. As previously posted it first reports error and then says complete. It may point to the drivers file. Then I will check to see if its installed.

Process Monitor

from Sysinternals will log all driver setup activities.


PonyProg

was suggested on Afterdown.com forum to get firmware from a similar device's EEPROM chip, and possibly upload back standard firmware extracted from your LME driver. It does require serial adapter though (see the site). It can help to ID the device you get and its real manufacturer at the least, so you can get it fixed or replaced, or get working factory firmware from them. But it seems to be for hard core hobbyists, shipping device back is often easier.

I asked Prog of ProgDVB who supports the Q-Box.

He pointed me to the TBS Q-Box DVB-S USB Receiver.

I downloaded the manual and drivers from there.

When I opened files, they had the same software title $CHICAGO$

There is a driver for the AMD processor but not the Intel.

Requested driver from support@tbsdtv.com

You have a tuner, someone on the web called QQ. Its not
Q-box

made by TBS, as I see it. You can find string $CHICAGO$ in most .inf files.

Surprisingly enough, I've got a reply from LME guy Liny today:
"Can your contact your vendor to check the hardward ? If possible ,please send me the dirver from your cd ."

They seems to be getting involved in your case. Can you post the installer .exe file from CD here or elsewhere, and give download link here. They will try to find out from the driver, who made this thing. Better yet, they can easily dissect it from the tuner's EEPROM. But at times such "No name" vendors install generic firmware, playing cat and mouse game.

Well, I'm confused. The driver files on the cd are the same as from the LME website. Which you can download.




DVB-S USB PCTV Driver

Maybe you should see if he will join this post like DVBWorld has done with their support people.
