The board is Waveshare PCIe→USB3.2 Gen1 board, and differs from the Waveshare PCIe→USB3.2 HAT+ in that it doesn’t ride on the hat and it doesn’t include an i2c eeprom, but the hat version doesn’t seem to need the eeprom to work on Tachyon anyways.
This board uses the same VLI IC as the working Waveshare PCIe USB HUB HAT+ below.
Same result on 20.04 and 24.04 1.1.43
