     37> On this page i found alternative firmware that could be used with this PCB. The Jmicron JMS577 chipset seems to be a special, vendor specific chipset that is interchangeable with the standard Jmicron JMS578 chipset. The JMS578 is a USB 3.1 Gen1 to SATA 6Gb/s bridge controller that supports UASP and has TRIM command support if a SSD is used.
