Yes. Console cables are often subject to physical wear, especially the small internal wires at the connector ends. If you have access to another cable (or another PC), test the cable in a different environment. Also, try a different USB port. Some USB ports do not supply enough power for the USB‑to‑serial converter.

You plug in the cable, and Device Manager shows an unknown device or “USB Serial Controller” under “Other devices”, with no COM port assigned.
