Bug ID: 195793
Summary: USB 3.0 support on Intel H97 chipset
Product: Base System
Version: 11.0-CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: usb
Assignee: freebsd-usb@FreeBSD.org
Reporter: quake...@gmail.com
It seems that the xhci drive is missing PCI IDs for the H97 chipset (haswell
refresh), limiting the USB 3.0 ports to USB 2.0 speed (ehci is used as a
fallback). This is my output from usbconfig:
q66@butts: /home/q66$ usbconfig
ugen0.1: <XHCI root HUB 0x8086> at usbus0, cfg=0 md=HOST spd=SUPER (5.0Gbps)
pwr=SAVE (0mA)
ugen1.1: <EHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE (0mA)
ugen2.1: <EHCI root HUB Intel> at usbus2, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE (0mA)
ugen1.2: <product 0x8009 vendor 0x8087> at usbus1, cfg=0 md=HOST spd=HIGH

ugen2.2: <product 0x8001 vendor 0x8087> at usbus2, cfg=0 md=HOST spd=HIGH

ugen2.3: <product 0x8142 vendor 0x0451> at usbus2, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (0mA)
ugen2.4: <ROCCAT Savu ROCCAT> at usbus2, cfg=0 md=HOST spd=FULL (12Mbps) pwr=ON
(500mA)
ugen2.5: <product 0x0825 vendor 0x046d> at usbus2, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=ON (500mA)
ugen2.6: <product 0x8142 vendor 0x0451> at usbus2, cfg=0 md=HOST spd=HIGH
(480Mbps) pwr=SAVE (0mA)
ugen2.7: <product 0x010d vendor 0x046a> at usbus2, cfg=0 md=HOST spd=LOW
(1.5Mbps) pwr=ON (100mA)
ugen2.8: <Samsung M3 Portable Samsung M3 Portable> at usbus2, cfg=0 md=HOST
spd=HIGH (480Mbps) pwr=ON (30mA)
The last item is an USB 3.0 external hard drive, being limited to 480 Mbps
(yes, it's plugged into an USB 3.0 port)
Here's my output from pciconf -l -v:
