Default MicroUSB no data connection

So, I got back this weekend and realized that the data connection over USB cables stopped working, even in recovery(PhilZ) mode.

Last weekend it was working fine, and throughout the week it was kept turned off with no disturbances.

ADB doesn't detect the phone.

Power is supplied normally, so the phone still charges. Computer plays the USB detected sound when plugging in/out.

Tried different cables, different computer, and verified that while it works normally on my One m8, it does not on my HOX.

On SlimKat rom, stock kernel.

Any help, guys? I'm really hoping it's not a hardware problem.
