We can't tell what chip is in it from picture. You would have to delve into windows setting / devices and see wht it think it is. Most likely it has loaded the driver for a different chip.

What car / ECU are you using it for? The KKL interface has limited functionality on newer cars with CAN buses. These need ELM 327 or similar interfaces.

I can"t connect elm327 on body and other modules, I can see motor comp, fiat stilo 1.6, 2002. Nor usb with CH340, nor bluetooth, nor wifi model with pic18F25K80. I used MES from 1.7 to 4.6r1 version. What is the problem?

Measure the resistance between pin 6 and 14 on the obd connector side.... If it reads 120 ohms it is a copy of the elm327... It must be removed by breaking the box open and removing the resistor.... Google elm327 120ohm....there are many variants of the copies.... Find one that looks lije your circuit layout and remove the resistor.... Some fixes call for 100ohm resistor and a capacitor connected to the pins 6 and 14.... This is a filter for noise suppression but i have used multiecuscan on a elm327 with only the resistor removed and can commnicate with all c can bus controllers
 
Can someone tell me if something needs to be changed in the connections so that the device opens all modules in fiat stilo? Thank you!

Suggest you read here: MES Supported Vehicles

For Stilo 1.6 many systems will work with the KKL Interface but for the power steering you will need adaptor P9. For Xenon P12. The switch on your KKL interface will only capter for no adapter and adapters P1 and P3.

For the other systems (listed in RED) you will need a working ELM interface.

Thanks for the photos of the inside, I was actually looking for PCB photos of these adapters.
If you or anyone has this adapter, please take few photos of PCB inside, would help a lot
