Hello,

> Do you have a XHCI controller on your computer which is capable of USB 3.0 ?

No, i have only USB 2.0 port in my computer. HDD is 3.0 and 2.0
compatible of course.

Under Ubuntu on same hardware, disk is connected as USB 2.0, spd
profile HIGH / 480Mbit.
Under FreeBSD, disk is connected as USB 1.1, spd profile FULL / 12Mbit only.

> This question you need to forward to the manufacturer of your drive!

I don't know what to ask them. It's FreeBSD problem i think.
Question is: Is it posible force FreeBSD to use profile HIGH and
connect HDD as USB 2.0 device?

Thanks Beam
