Sounds new enough :-)
My USB3 disc on my newish laptop with USB 2 socket & 8.2 & 9.0 come
up fast enough, not noticed problems, not specificaly timed it though.
Try external power if you have a socket on disk box ?
Try disk on another known good FreeBSD USB3 card on a tower (my card cost
30 Euro BTW)
Or try a power doubler cable (connected via a female to female
adapter, which Ive never seen on sale, I made my own by cutting up
a dead mainboard), to the USB 3 male to male cable. (for any who
dont know, cant omit that cable as USB3 socket on lapop size drives
is a different shape, flater, wider.
I wonder if it might be taking time dropping back to USB2 speed.
if eg you don't have xhci in kernel ?
I have all of
config -x/boot/kernel/kernel | grep hci
device uhci
device ohci
device xhci
device ehci
I just havent taken some out yet.
Cheers,
Julian
