Great Bryan, the model of your USB controller is the same reported in this LP; also, given the outputs you provided, the network interface "enx90203a19dcb6" in under one of those USB controllers - you mentioned you see the TRB DMA errors and the interface stops responding. Is the problematic interface that one, "enx90203a19dcb6" ?
Who is the vendor of your device? I'd suggest you to seek help from them, mentioning this LP and that ASMedia may have a potential firmware fix for the issue.
