Which USB device did you uninstall/re-install? I do not see the Packtalk listed as a separate device under 'USB Serial Controllers' or anywhere else in the Device Manager list. That is with the Packtalk plugged into a USB port and whether or not the Cardo Updater (V3.0.1) is loaded or not. The DM page updates when the PackTalk is plugged in as it should when ANYthing of a USB-sort is attached to the system (Windows 10), but I see nothing on the list that changes after that list refresh. USB devices CAN show up in the list. I have an older Samsung phone running on Verizon that shows up. The Packtalk is not one of those that does show up that I see. A bit of elaboration would be appreciated. Thanks!
