hello
I'm looking for some assistance with the coms ports.
I'm currently using a pololu tic T825 stepper controller and an nema11 stepper motor, this setup worked fine on INDI on astroberry, but now Ive moved to NINA and need to run it ascom style.
So the issue Ive got is the controller is connected to the USB serial bus in the device manager on win11, but the ascom focuser only wants to connect to the controller on com3, which is also the port for my mount.
I cant for the life of me figure out how to tell the ascom driver or the aplication that the controller is connected to the usb interface serial bus and not on com 3.
ive included a screenshot of my device manager and the focuser application.
ASCOM and drivers adhere to specific standards and is highly integrated into using comports for devices. Only recently has ASCOM extended to include network aware devices (ALPACA).
This means that ASCOM drivers are written to work with Serial ports. When the device (like myFP2) is plugged into a USB port, Windows will assign it a Com Port name and use a serial device driver to access the controller.
What you are referring to is called HID or Human Interface Devices, which is a device that Windows can recognize and talk to. When an HID device is plugged into a usb port, Windows will recognize it and handly it differently compared to a Serial port.
ASCOM standard does not support HID. Whilst one might be able to hack some code to generate one, in my opinion, such a hacked drive would probably never be able to pass "Comform" tests for an ASCOM driver. However, I could be wrong. It might be that some-one has already done this for some other project.
If you are trying to use a HID device (like your pololu tic T825 stepper controller) then you are out of luck as the myFP2 project does not work with HID devices, and there are no plans to do this in the future. if your are trying to get an ASCOM driver to work with your HID device, you will not find one here.

hello again i should of included this, its the pololu control center software that shows the details for the board.
thanks again

Most of these HID focusers use USB com port for ASCOM and HID for Windows. Please see

Apolgies if this was not the answer you were expecting
