This may have already been covered,butwhats the deal with Windows xp virtual machine and Moto software.Yesterday I was reading a CM300,sucessfully,ONCE

1.Plug in USB cable,which is port 3
2.Got to USB and click on attach.
3.Then read,but when I first used any software,I had to setup the port when I first use software.
4.Waris seems OK,along with Trbo.Have not really tried any Mag one software for BPR 40.
So anyway,it seems as though I have port issues,any suggestions?
Thanks.
