For Linux enthusiasts: The ASM2364 exposes configuration descriptors via the /sys/bus/usb/devices/ interface. Using the asus-m105 tool (modified for ASM2364), you can adjust:
ASMedia provides a utility known as (Mass Production Tool) to its OEM partners (the factories that make the enclosures). This tool is not intended for end-users. It is a complex, industrial-grade software used to flash the firmware during the manufacturing process.
Before diving into the firmware, it is essential to understand the hardware it controls. The ASM2364 is a PCI Express (PCIe) to USB 3.2 Gen 2x2 bridge controller. If you have located an MPTool variant and
While most users simply plug in their enclosure and expect it to work, enthusiasts and professionals know that the software running on the device—the firmware—is critical. Understanding is the key to unlocking higher speeds, maintaining thermal efficiency, and resolving compatibility issues.
In the world of external SSDs, the bridge chip is the silent gatekeeper of performance. For years, the market was dominated by the ASM2362 (10Gbps) and the Realtek RTL9210B. However, the introduction of the changed the game.
You cannot flash random firmware. First, identify what you have. : Features self-designed PHYs and integrated CC logic
Only use firmware provided by your specific enclosure manufacturer.
Last updated: October 2025 – ASMedia is rumored to be working on a final “2409xx” branch before EOL.
