As useful as USB-to-M.2 SSD adapters are, sometimes you come across a bit of a dud. A case in point is the Orico-branded TCM2-C3 that features both an attractive clear case and in its earlier revisions a JMicron controller-based circuit that apparently degrades over time, causing erratic boot behavior. After implementing a fix a few years ago, [Mark Furneaux] can happily report that the thus fixed enclosures are still working.
These faulty board revisions feature the JMicron JMS583 controller IC, which has a 1.0V core voltage input pin. Apparently to save power, Orico designed the board to target the minimum ~-0.95V core voltage per the datasheet. Apparently due to component drift or degradation, this lower core voltage is after a while often not enough any more to start the controller, which thus translates into an unresponsive USB device and presumably some panic about lost data.
Although [Mark] doesn’t describe the fix in detail, it entails bumping up this core voltage to something closer to the nominal 1.0V, which restores functionality at the cost of presumably a measurable amount of extra heat production by said controller.
Later versions of the Orico TCM2-C3 enclosure switched from this JMicron controller to a Realtek one, which so far appears to be noticeably more reliable. Although Orico kept the same model name, the transparent enclosure makes it at least a snap to see which revision you are dealing with.
