Discussion - Drivers / How to get stable COM-ports for different USB port in PC in Windows 10?
« on: August 30, 2021, 02:28:07 PM »
Hi,
I am using a device with FT4232 (VID 0403, PID 6011). If I need to plug it into a different USB port on PC, it will allocate new com port number.
I have tested it on 3 PC (four Windows 10). Two PC are good (no new COM port numbers), two computers allocate new com port numbers.
1) PC HP desktop - Windows 10 PRO - FTDI driver version 2.12.28.0 -> updated continuously ->No problem
2) PC HP desktop - Windows 10 PRO - FTDI driver version 2.12.36.4 -> updated continuously -> Every USB port has own COM port numbers
3a) DELL Optiplex 3080 micro - Windows 10- IOT - Enterprise - LTSC - 1809 - created and updated 7.5.2021 and now -> driver version 2.12.28.0 ->No Problem
3b) DELL Optiplex 3080 micro - Windows 10- IOT - Enterprise - LTSC - 1809 - (created 7.5.2021 and updated continuously) driver version 2.12.28.0 - Every USB port has own COM port numbers
On PC 2 and 3b was problem, I tried uninstalling the driver and installing a new one (2.12.36.4). No success.
Could you tell me where is a problem? Why some PC with FTDI device works correctly and some no? Do you have any idea how to fix it or make sure it doesn't happen again.
Thank you.
