The board's power supply checks out as OK? If so, there's no way a properly functioning board and its power supply could generate 90 V, so I suspect something happened to the power supply on your PC.<BR /><BR />You'd want to try--carefully--the board on a another PC anyway to get a second opinion.<BR /><BR />---Tom<P>Message Edited by J2MEJediMaster on <SPAN class="date_text">2006-08-15</SPAN> <SPAN class="time_text">10:18 AM</SPAN></P></BODY></HTML> Tue, 15 Aug 2006 21:17:55 GMT https://community.nxp.com/t5/S12-MagniV-Microcontrollers/usb-multilink-broken/m-p/125517#M335 J2MEJediMaster 2006-08-15T21:17:55Z
