So I tried multiple cards of exactly this model (BEYIMEI PCI-E 4X to 6-Port) and another one from MZHOU (also sold on Amazon; quite sure it's the same card). All cards have the ASM1166 chip and I was getting them to replace two hbas on an Intel Z690 motherboard. I've tried to upgrade the firmware on a total of 4 different workstations, including 2 Ryzen builds (1gen and 3gen on Asus motherboards) and two Intel ones (x99s and z97s MSI motherboards) to no avail. In my case, the firmware flashing tool just did not recognize any of those cards. Reseating PCIe slots, hard-setting PCIe generation and a lot of other settings did not help there. While some were useable with the correct drivers on Windows, I simply could not get the flashing tool to recognize the cards. The only vendor I could find around here (Central Europe) that also sells cards with an ASM1166 chip was SilverStone (ECS06 model). It's pricier but they provide the flashing tool and firmware on their website. The card was recognized immediately and the firmware upgrade was also successful. To be honest, I have no idea what the actual problem was but at least the last ditch effort was successful. In any case, thanks for the information on the firmware upgrade!
