IC-718 Using Rigtalk CAT CIV, Signaliknk USB and HRD - everything connects fine with a desktop w/xp - but fails to read frequency and connect using a laptop. I have HRD on two laptops - one with xp and one with Windows 7. Both laptops work fine connected to my TS2000 - using serial to USB . I have updated the drivers from device manager. Any suggestions??
