Hi Hans, We have tried using a SSD disk with a USB 3.1 gen 2 to SATA bridge device (XHCI 1.1). The disk is detected and usable. But seems it works in "Bulk-Only" mode. Is there any plans to support USB attached SCSI? I see a tunable "hw.usb.xhci.streams" to enable USB streams. But seems it does nothing much.
