ChangyeobOk When I said all get positives, it meant the result of "i2cdetect -y 1"
Is it normal?
No, it's an error on the bus. Most probably the SDA line is shorted with GND, but could also be something else.
Are you getting that result with no KCeptor connected? If so then you should focus on finding some soldering issue in the Hub first. Do you have a tester? you can test continuity between SDA and SCL, and also btw them and ground.
What happens if you unplug the Hub and run
The solder bridges in the KCeptor @valor is pointing out will probably give you communication errors as well, but if understood the situation correctly they are not the cause of your current issue.
