HTC one x doesn't remember debug mode

Question

When I connect any Android Smartphone which I previously used to debug to my pc, normally it automatically sets the debug mode enabled. Somehow since a few weeks my HTC one X stopped doing this. Everytime I connect my smartphone I have to manually select the USB Debug mode to be on.

UPDATE

It looks like the bug could be even worse. If I switch my top right button to on, but leave the bottom "debug mode" off, my phone still starts debug mode. After a while it somehow detected that it wasn't in debug mode and jumped back out.

Answer 1

The solution was simple, simply disable and enable the Debug options (top right button "ON")

UPDATE Though it worked for a day or so, the trick didn't last long

UPDATE Software update did the trick. Apparently this bug was only present in 4.2.2 (at least in combination with HTC sense)
