dd back to 10 current

ehci0: <Intel Panther Point USB 2.0 controller>
ehci1: <Intel Panther Point USB 2.0 controller>

usbus0 on xhci0
usbus1 on ehci0
usbus2 on ehci1

usbus0: 5.0Gbps Super Speed USB v3.0
usbus1: 480Mbps High Speed USB v2.0
usbus2: 480Mbps High Speed USB v2.0

ugen1.1: <Intel> at usbus1
ugen0.1: <0x8086> at usbus0
ugen2.1: <Intel> at usbus2

uhub0: <Intel EHCI root HUB...> on usbus1
uhub1: <0x8086 XHCI root HUB...> on usbus0
uhub2: <Intel EHCI root HUB...> on usbus2
// hub doesn't number accordingly to usbus number?

first test =3D while pendrive boot from usbus0 (USB 3.0)
---------------------------------------------------------
ugen0.2: <Kingston> at usbus0
umass0: <Kingston DT 101 G2=2C class 0/0=2C rev 2.00/1.00=2C addr 1> on usb=
us0
umass0: SCSI over Bulk-Only=3B quirks =3D 0x0100
umass0:3:0:-1: Attached to scbus3

second test =3D while pendrive boot from usbus1 or usbus2 (first one)
(idk how to number and confirm their number)
---------------------------------------------------------------
ugen0.2: <Kingston> at usbus0

third test =3D while pendrive boot from usbus1 or usbus2 (another one)
(idk how to number and confirm their number)
---------------------------------------------------------------
uhub0: <0x8086 XHCI root HUB...> on usbus0
uhub1: <Intel EHCI root HUB...> on usbus2
uhub2: <Intel EHCI root HUB...> on usbus1
// different from previous info

ugen1.3: <Kingston> at usbus1
umass0: <Kingston DT 101 G2=2C class 0/0=2C rev 2.00/1.00=2C addr 1> on usb=
us1
umass0: SCSI over Bulk-Only=3B quirks =3D 0x0100
umass0:3:0:-1: Attached to scbus3

I don't know if the numbering of uhub is changeable based on where user plu=
g in their pendrive=2C seems unusual to me.
