Thanks for the feedback. I switched to a 1000 w 4 rail psu with 25a on each rail. I just connected it to the 16Hex4E and it powers on, but i dont see any hashing.
A screenshot of your cgminer screen and lsusb output also?
Did you upgrade de the tplink recently?
If yes just make sure that cgminer starts and exec /usr/bin/fix_rc
