Do you have enough parts to cross-check the non-functioning items with other hubs? That way you could narrow down the problem scope - as of now, it can be in the NXT hub internal hardware, the firmware, your software, the port on the NXT side, the cable connector, the cable itself or the end device (sensor/motor).

Thanks for the reply, I changed the capacitor C61 and everything worked again.

If you'd write an answer detailing how you managed to find and fix the problem I'd definitely upvote it. If you could add photos to help others with the same problem, I could add a bounty as well.

* Motors do not respond to degrees or rotations;
* Ultrasonic Sensor and Color Sensor are not working;

My Firmware version is V1.31. What can it be?
