Hello, On this server : FreeBSD megaptera.semiocast.net 9.1-RELEASE FreeBSD 9.1-RELEASE #1 = r250855M: Tue May 21 15:14:41 UTC 2013 = root@megaptera.semiocast.net:/usr/obj/usr/src/sys/GENERIC amd64 I do have two USB 3 cards handled by xhci driver and with VIA chipset. > xhci0@pci0:5:0:0: class=3D0x0c0330 card=3D0x34321106 = chip=3D0x34321106 rev=3D0x03 hdr=3D0x00 > vendor =3D 'VIA Technologies, Inc.' > class =3D serial bus > subclass =3D USB > xhci1@pci0:6:0:0: class=3D0x0c0330 card=3D0x34321106 = chip=3D0x34321106 rev=3D0x03 hdr=3D0x00 > vendor =3D 'VIA Technologies, Inc.' > class =3D serial bus > subclass =3D USB The cards are identical. Here is an excerpt from /var/log/messages : > May 22 10:56:52 megaptera kernel: pcib5: <ACPI PCI-PCI bridge> at = device 9.0 on pci0 > May 22 10:56:52 megaptera kernel: pci5: <ACPI PCI bus> on pcib5 > May 22 10:56:52 megaptera kernel: xhci0: <XHCI (generic) USB 3.0 = controller> mem 0xdf4ff000-0xdf4fffff irq 40 at device 0.0 on pci5 > May 22 10:56:52 megaptera kernel: xhci0: 32 byte context size. > May 22 10:56:52 megaptera kernel: usbus0 on xhci0 > May 22 10:56:52 megaptera kernel: pcib6: <ACPI PCI-PCI bridge> at = device 10.0 on pci0 > May 22 10:56:52 megaptera kernel: pci6: <ACPI PCI bus> on pcib6 > May 22 10:56:52 megaptera kernel: xhci1: <XHCI (generic) USB 3.0 = controller> mem 0xdf5ff000-0xdf5fffff irq 41 at device 0.0 on pci6 > May 22 10:56:52 megaptera kernel: xhci1: 32 byte context size. > May 22 10:56:52 megaptera kernel: usbus1 on xhci1 Card in bottom slot (PCI 5, xhci0) works properly. The card has 4 = external ports and all four ports are currently used. When I plug a device in card in top slot (PCI 6, now card xhci1) in = either of the 4 external ports, nothing happens. Both cards are new and seem to work. Indeed, previously only the card in = top slot (PCI 6) was inserted and it worked properly. But when both = cards are inserted, only xhci0 seem to work, as if xhci1 was conflicting = with xhci0. There are two other (physical) PCI slots in this machine = with other non-USB cards and they work properly. The motherboard also = has plenty of USB 1.0 and 2.0 buses and the external ports work = properly. Here is the output of usbconfig : > ugen0.1: <XHCI root HUB 0x1106> at usbus0, cfg=3D0 md=3DHOST spd=3DSUPER= (5.0Gbps) pwr=3DSAVE > ugen1.1: <XHCI root HUB 0x1106> at usbus1, cfg=3D0 md=3DHOST spd=3DSUPER= (5.0Gbps) pwr=3DSAVE > ugen2.1: <UHCI root HUB Intel> at usbus2, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DSAVE > ugen3.1: <UHCI root HUB Intel> at usbus3, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DSAVE > ugen4.1: <EHCI root HUB Intel> at usbus4, cfg=3D0 md=3DHOST spd=3DHIGH = (480Mbps) pwr=3DSAVE > ugen5.1: <UHCI root HUB Intel> at usbus5, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DSAVE > ugen6.1: <UHCI root HUB Intel> at usbus6, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DSAVE > ugen7.1: <UHCI root HUB Intel> at usbus7, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DSAVE > ugen8.1: <UHCI root HUB Intel> at usbus8, cfg=3D0 md=3DHOST spd=3DFULL = (12Mbps) pwr=3DSAVE > ugen9.1: <EHCI root HUB Intel> at usbus9, cfg=3D0 md=3DHOST spd=3DHIGH = (480Mbps) pwr=3DSAVE > ugen0.2: <USB2.0 Hub vendor 0x2109> at usbus0, cfg=3D0 md=3DHOST = spd=3DHIGH (480Mbps) pwr=3DSAVE > ugen4.2: <product 0x2514 vendor 0x0424> at usbus4, cfg=3D0 md=3DHOST = spd=3DHIGH (480Mbps) pwr=3DSAVE > ugen0.3: <Ext HDD 1021 Western Digital> at usbus0, cfg=3D0 md=3DHOST = spd=3DHIGH (480Mbps) pwr=3DON > ugen0.4: <Ext HDD 1021 Western Digital> at usbus0, cfg=3D0 md=3DHOST = spd=3DHIGH (480Mbps) pwr=3DON > ugen0.5: <Ext HDD 1021 Western Digital> at usbus0, cfg=3D0 md=3DHOST = spd=3DHIGH (480Mbps) pwr=3DON > ugen0.6: <Ext HDD 1021 Western Digital> at usbus0, cfg=3D0 md=3DHOST = spd=3DHIGH (480Mbps) pwr=3DON I am confused about the lack of ugen1.2 in this output. Could that be = relevant? What can I do to debug this issue? Regards, Paul --=20 Semiocast http://semiocast.com/ +33.183627948 - 20 rue Lacaze, 75014 Paris
