Alterar o slot PCIe, em seguida, trocar a placa USB 3.0 pelo mesmo modelo não ajudou. Eu tentei desativar o USB on-board (2.0), e isso resolveu meu problema. Parece haver um conflito com USB 2.0 e USB 3.0 com o FreeBSD.
Versão do FreeBSD: 10.3 Modelo da unidade Seagate: Adaptador SRD00F1 USB 3.0: Placa host USB 3.0 Insignia PCIe (NS-PCCUP53)
Quando eu reinicio com a unidade já conectada, ela não é vista. Mas, quando eu conecto a unidade, vejo o seguinte no dmesg.today:

Qualquer ajuda seria muito apreciada!
