USB \ VID_1A86 & PID_7523 is CH340 / CH341 chip identification not FT232. Drivers for CH340 / CH341 attached.

Just search.

daniel95 · Answer

Yes. I looked but I can't install it: / because I don't know what file format it is. And where to upload this file / files?

grala1 · Answer

After inserting the cable into the USB, if the system does not find the driver, it will ask you to indicate the location of the driver and then you will point it to it.
You can put it in the SYSTEM32 / DRIVERS folder in WINDOWS.

daniel95 · Answer

I did girla1 as you write and it still does not see the system driver: / I also tried to point it to the target and automatically. Any other suggestions on how to start it?

tzok · Answer

There were a lot of cables on the counterfeit FT232 chips, which were blocked by the driver provided by Windows Update. Provide the hardware identifier (PID, VID) from the device manager.

daniel95 · Answer

I don't know if that's what you meant. USB \ VID_1A86 & PID_7523 & REV_0254 USB \ VID_1A86 & PID_7523

Hello
I'll reheat the cutlet because I don't want to create a new thread.
What is the reason why the advanced properties of the USB port cannot be changed after installing the drivers for the Facebook? In my case, when I enter the advanced settings, I have "Use FIFO buffers" and two sliders for the receive buffer and the transmit buffer. Lack of possibility to select transmission buffers (sliders and settings from 4096 to 1024).
Thanks in advance for the info.

PiotrT · Answer

You probably have an interface with a CH340 / 341 chip. In this case, these settings cannot be changed.

Pioter.K · Answer

Hello Is it good or bad?

tzok · Answer

Badly. Cables based on different variants of the FT232 chip work much more stable and connect to a larger number of modules.

Pioter.K · Answer

Hello, you cheered me up. One more question about this Chip 340T. After installing the drivers, I only have a mention in the device manager in the port (COM, LPT) with the content USB-Serial CH340 (COM2). There is no mention of an interface in Universal Serial Bus Controllers. Is that good or is there something else missing from the system? WinXP system.

Hello, maybe someone will be able to help me explain why I do not want to detect the KKL VAG-COM for 409.1 cable. The drivers are supposed to be, in the device manager it shows CH340 in the USB-SERIAL ports, but after starting the VAG-COM program, it shows the message Port status: ok Interface: not found.

PiotrT · Answer

Interface power supply connected and appropriate COM port selected on VAG-COM?

malqsch · Answer

COM3 port selected both in the program and in the device manager, anyway, the game because the program shows Port: ok, and when I change the name of the port, it does not even detect it. The power supply probably works because after connecting the cable, the LED on the other end of the cable lights up.

tzok · Answer

For the test, the cable must be connected to the 12V power supply from the side of the OBD-II plug, i.e. plugged into the car.

malqsch · Answer

People on the forum previously wrote that it does not have to be connected, i.e. that without connecting it to the car, it should show that the interface is there, but no connection to the car. For me it shows no interface.

tzok · Answer

And I write to you that it must be connected ... plug in, you will see.

PiotrT · Answer

This LED often indicates that the interface is powered from the USB port Therefore, during the test, the interface is to be connected to the power supply from the installation, i.e. + 12V.

I will join the topic. I have the same problem as my colleagues above. CH341SER driver installed, lots of different programs and none of them want to detect interface Continuous message Port status: ok Interface: not found and so on. Tried other random drivers but no changes. The port in the manager is the same as in the program. I checked, including as an administrator, on two different laptops with win7 and win xp, connecting to the car and not. I have no idea what to do now. Anyone help me connect to the car?

pepe150 · Answer

CH341, I only think of a programmer for I2C memory. So this driver won't get it. Look for FTDI or Profilic. Because they are popular RS232 controllers.

xmariomx · Answer

I did with FTDI but I don't know if it's good. I first installed it as a serial bus controller - nothing found and had no port. Then I installed it like a port (I installed different versions) and then interface: Not Found error. Of course, I check now without a car, but it should be up to the vaga anyway. I have no idea how to make a Profilic.

tzok · Answer

You only have to install the drivers for the system your cable is on - based on the hardware ID. After installing the correct driver, a virtual COM port (USB Serial Port) will appear in the system and that's it. The program will not detect any interface that does not have a 12V power supply from the OBD-II plug.

xmariomx · Answer

Now i do not understand. Device ID: USB \ VID_1A86 & PID_7523 & REV_0254 USB \ VID_1A86 & PID_7523. After connecting the device, I have USB2.0- Serial without a driver, I install the driver on it as a universal serial bus controller (installs twice on the same device) and the second time I install I have a blue screen - the driver is not installed. Only installs digitally assigned drivers. It is enough to install the COm and LPT port once, but I do not have how to check now if it will actually see the vag only when I connect to the car.

tzok · Answer

So you have a cable on the CH340 chip and you have to install such a driver, not some universal serial bus controller. The driver is here: ... or directly from the manufacturer's website: Description of the installation here:

pepe150 · Answer

After VID and PID it finds CH340 - not CH341. There are converters for CH340 to serial. The link to the drivers is given from a certain store (Polish):

tzok · Answer

There is the same driver for CH340 and CH341 ...
