The IDE installs. It appears during setup USB drivers are installed. On completion USB 2.0 cable shows its connected with green led. Also amber led shows. However, no Arduino ports are visible in Device Manager, a msg 'disconnected ' appears in the IDE. No port menu item available to show a port or scan for a port when the Arduino UNO R3 board is selected. No idea how to verify usb drivers setup in Arduino IDE...
Anything with yellow triangles in Windows device manager? If not, try different cables.
You might have a clone with a CH340 TTL-to-USB converter in which case you need to install the driver; you can download it from CH341SER.ZIP - NanjingQinhengMicroelectronics.
Hi, Thanks for replying. Yep I've tried those eg the following: How to Install CH340 Drivers - SparkFun Learn

but installing the Sparkfun CH341SER.EXE didn't solve it still no port generated. I've also enabled extra features in windows/programs and features these mostly related to .net might fix it.
I clicked your link and tried again and in the setupwin64 type folder it installed the .inf it found there. I checked this with a few cables same result.
No connection is being made by Arduino IDE 2.0.2 to a port in Device Manager on my win 11 Home edition. Tomorrow, I'll try it on another pc running win 10...
I replaced the Arduino R3 with a new Arduino R3 SMD. This on connecting generated a com port and its driver is working fine.
The other one I did manage to create a com port for it using Device Manager Add Hardware wizard and selecting com to add one. This succeeded but generated a red flag beside it. I tried to update its driver with the CH340 driver pkg I downloaded. But installing driver attempts got msg unable to start device.
Also while the green led comes on the amber led that should blink instead blinks on startup then stays on. On closer inspection I believe there may be some damage to the external power connector dunno if fixable.
Adding a com port in Windows device manager will not help if the board is not recognised. Windows either does not see it or it does not know what to do with it.
Did your 'broken' board work in the past? What is the TTL-to-USB converter on it? If it was working in the past, what was the last project that you were working on that you could successfully upload? Do you have a link to what your bought?
