that seems to be an RFI issue; USB connections, especially hubs are prone to RFI and will disconnect devices at the slightest level of interference. This is probably due to noise on the USB 5V line as that line is already used to detect USB device disconnection. I've found that laptop mouse pads are particularly prone to this issue. 73 Bill G4WJS. ------------------------------------------------------------------------------ _______________________________________________ wsjt-devel mailing list wsjt-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/wsjt-devel
