The CSV-1583 should be able to supply up to 96W to the host.
Which model Asus laptop do you have? Are you sure it has a Thunderbolt port that accepts power delivery?
Do the Thunderbolt functions of the CSV-1583 work? I believe it supports two displays connected to GPU (using Thunderbolt DisplayPort tunnelling to the downstream Thunderbolt port and the 8K DisplayPort port) and two displays connected to USB (using DisplayLink drivers that output to the two pairs of HDMI/DisplayPort ports).
Is the 2.5 GbE supplied by PCIe or USB? I suppose it must be USB if it works for non-Thunderbolt or non-USB4 hosts (i.e. for USB-C DisplayPort Alt Mode hosts).
