My Window10 computer has 4 USB C ports and a 7 port USB3 hub. I have 5 different Elecraft USB Serial ports connected and they always receive the same com port number regardless of which USB port or HUB port they are plugged into. K3s, KAT500, KPA500, KX3, SG3 and other non Elecraft devices.
I have never had them change as a result of a Windows upgrade. 73 - Mike - K9JRI > On Apr 25, 2019, at 5:08 PM, Don Wilhelm <donw...@embarqmail.com> wrote: > > Windows will usually assign the same port number IF you plug it into the same > USB port. > > You can go into Properties for each device and change the port number - COM1 > and COM2 are usually reserved for serial ports on the motherboard, even if no > RS-232 ports are present on the board. > > 73, > Don W3FPR > > On 4/25/2019 4:14 PM, David Haines wrote: >> Thanks for the confirmation.
