--- Comment #7 from Hans Petter Selasky <hselasky at FreeBSD.org> ---
Is this output the same for both USB 2.0 and USB 3.0?

Warner:

Why is the data transfer 8K for a sense length of 252 bytes?

ccb->csio.dxfer_len = 8192, ccb->csio.sense_len = 252

umass1:umass_cam_action: 6:0:0:XPT_SCSI_IO: cmd: 0x2a, flags: 0x80, 10b
cmd/8192b data/252b sense
