frebird0798@gmail.com Posted December 16, 2012 Share Posted December 16, 2012 Running win7 64 bit, show was working fine. Unplugged it for a few days. i come back and won't work anymore. I go into hardware utility and I get a comm port error. When I plug in the USB to the USB485 its like the computer doesn't see it. In harware utility there are no comm ports to pick and auto doesn't find anything? Bad USB485? Link to comment Share on other sites More sharing options...
George Simmons Posted December 17, 2012 Share Posted December 17, 2012 Could be.Could also be a bad or corrupt LOR installation.Could be a Windows update did something.You didn't mention rebooting the PC. Unplug the USB485, reboot, after Windows completely reboots then plug the USB485 back in. Link to comment Share on other sites More sharing options...
frebird0798@gmail.com Posted December 17, 2012 Author Share Posted December 17, 2012 Turns out it was a bad USB485, was very surprised to get email support on a sunday from Light O Rama. Still under warranty and they are shipping one today. Link to comment Share on other sites More sharing options...
