It may be worth trying with a cellphone/similar to confirm your cable(s) carry data too. Alternatively, you may be using a power only USB cable, however you've already tried several different cables. Micro-B is known for being a fragile connector.

If Windows does not detect the keyboard at all, there's a decent chance the micro-B usb port has been damaged. If there's already a generic driver installed, try uninstalling it with ' Uninstall device', and then running the Yamaha USB-MIDI installer again. While these generic drivers usually work fine, once in a while they can stop the proper device driver from installing. If this process has already happened, there is a chance a generic/Windows default driver has been installed. The screenshot you posted last week mentioned to stop the 'found new hardware' wizard if it pops up. Does Windows and/or Device Manager recognize your keyboard when you plug it in? Does it show up as a MIDI keyboard? (highlighted) Does it show up as 'Unknown Device'? (red circle).
