Yes I have a USB logger I clicked on USB and it worked OK. But it changed something in the logger per Davis support so it is USB only. There are no com ports. I then clicked on serial it shows the com port but will not find them. There is a program in the Weatherlink 5.8 directory to change the logger back to serial but it does not work and gives an errors. The program USB to CP210X.ex? has a bug and will not change logger back to serial with virtual Com ports. Davis is sending me a logger USB that will work. I removed 5.8 and re installed 5.71. IF IT WORKS LEAVE IT ALONE! Joe
