I have a RocketU USB3.0 1144B with 4-ports, but two of the ports are dead in linux. When I installed it in a windows machine I got 4 ports so I believe it's working. The card has 4: asm1042 88w23168a3 1218 1: plx technology pex8609-ba50bc 1: pi6c 20800sae I have consistently seen two AS Media devices in lspci output: 0000:0a:00.0 USB controller: ASMedia Technology Inc.
