Hi Steven I already done that, there isn't any logic in this, i tested after each line, with same result. the 7. Jan. 11 to 13 i recorded a show 13.30 i updated the Driver to 1.0.1.8 13.45 port C and D malfunctioned - roll back to 1.0.1.5 - restart - power down, wait one minute, re powered - run sys...
I have measured the voltage of each port the idle is A 1,1V B 1,1V C 19,3V D 1,1 When i eg. start IP tool at the different ports i get. A 13,4V B 13,4V C 19,3V D 1,1V So it is showing the same, port C and D are bad, it think the is defect.
After i updated my TBS 6984 to v.1.0.1.8, port C and D don't work. I have tried to restore Win7 to before update, but it still dosn't work. Any suggestions??
