If you have spent hours fighting driver issues, the simplest solution is to purchase a cable that is known to work out-of-the-box. Look for these features:

Avoid cables that are suspiciously cheap (< $3) and labeled only "AWM 20251" with no chipset info – those often contain obsolete Prolific chips.

Recommended alternatives:

With USB-C taking over, many newer laptops lack USB-A ports. However, the AWM 20251 remains relevant because enterprise network gear still uses legacy RS-232 console ports. In 2026, manufacturers are transitioning to micro-USB or USB-C console ports, but the installed base of Cisco 2960/3560/3750 switches ensures this adapter will be needed for years.

Alternatives to consider:

Pro tip: Keep a copy of the legacy Prolific driver v3.3.2 on a USB drive. When Windows Update pushes a newer version, it can break your cable. Use the “Roll back driver” feature. Awm 20251 Console Cable Driver Download

Go to the official WCH website or a trusted mirror like www.wch-ic.com. Look for "CH341SER" (USB to Serial Port).

First, let’s decode the label. AWM stands for Appliance Wiring Material. The number 20251 is a UL (Underwriters Laboratories) style code that specifies the cable's construction—typically 28 AWG stranded conductors with PVC insulation. In networking, this cable is almost always a USB to RS-232 Serial Console Cable, often equipped with a Prolific PL2303 or WCH CH340 chipset inside the USB connector.

Common uses:

The challenge? Modern operating systems no longer include legacy drivers for these chipsets. Without the correct driver, your PC will not recognize the cable—or worse, it will show a dreaded “Code 10” or “Code 28” error.

Before diving into drivers, it is crucial to understand what the "AWM 20251" designation actually means.

AWM stands for Appliance Wiring Material – a UL (Underwriters Laboratories) certification style. The number 20251 refers to a specific UL style for cables rated at 80°C and 300V, typically consisting of shielded, twisted-pair wires with PVC insulation. In simple terms, AWM 20251 is not a brand, nor a chipset, but a physical cable construction standard. Official Source: FTDI Chip – www
