Installed the most recent version.

I get into the recovry and when I plug it into a computer Windows will keep making the "unplugged"-noise.
I can see the sdcard-directory perfectly when I hit install in both, TWRP and CWM but when I want to mount it via USB it will not change anything and I cannot access it on my PC.

adb doesn't list any device either.

Also, TWRP and CWM keep telling me that my phone is not rooted, when I try to power off or restart. Is that normal?

My other HTC One X (non AT&T) just works fine with cwm 5.*.*.*
