I have a new HP laptop running Windows 11 Home. It has a AMD Ryzen 3 3250U (2.6GHz) with 8GB ram and x64-based processor.
I am trying to flash a firmware update onto a cnc via USB but I need to connect to an available Com port. Unfortunately, nothing comes up in the list of com ports. I did some research on various forums and read something about going into Device Manager, clicking actions and adding 'legacy hardware'. A variety of com ports were available (including HP and Windows) but after adding, I received the dreaded yellow sign with exclamation mark with a reference to error 34. Other threads about assigning com ports seems to require a CS degree. I really don't want to try making any system level changes without knowing exactly what I'm doing so...I'm hoping someone here can assist.
Thanks so much.

Ten years ago, I had to start to use USB-serial adapters because no COM port on notebooks. The problem was no standard therefore IBM supplies adapters did not work on Thales devices and vice versa. I retired 4 years ago and by that time I did not have to use adapters because their hardware started using network connections.
You need USB adapter. As I said above, no standard therefore you have to ask vendor to see which one is OK for your need.
