Even high end motherboards tend to only bring out 1 or 2 root hubs. That the chip supports 4 root hubs does not mean all of them were used. Typically there are two groups of USB3 and one or two groups of USB2. The mobo specs say I should have 6 USB2 ports (two on the rear plus two headers), 4 USB3 ports on the rear (three Type-A and one Type-C,) plus two USB3 headers. I know there is another USB3 hub in the chipset which is not available through the mobo. dmesg and lsusb show two USB2 hubs and two USB3 hubs (one of which is clearly the unavailable one.) Where is the extra USB2 hub coming from and where is the missing USB3 hub? Sometimes it's just one USB3 root hub and they attach all of the USB2 ports to it, making everything run at USB2 speeds. But connecting a USB2 device to a USB3 hub will slow things down, but they should not cause a USB3 hub to be identifed as USB2, just to work at the lower speed. Am I wrong about this? With USB2, hubs are required to have a translation unit that speeds USB1 packets up to USB2 speeds. Even with these translators you can incur delays waiting for slower USB1 devices to respond as they will take ~4x longer, and then the buffered data is sped up when it is put on the bus. With USB3 there is no such requirement. This would be fine as the USB2 is on separate wires but most USB3 silicon seems to be implemented in such a way that USB2 transactions slow down the USB3 transactions. In some cases this is visible with `lsusb -t`: putting a USB2 device on a USB3 bus will downgrade all devices to USB2 speeds (showing USB3 devices that were 5000M as 480M), and even if it is not visible, you may see transfers take ~10x as long. I found all of this out when benchmarking flash drives. My motherboard was wired such that every important USB3 port shared the keyboard and mouse ports. If you plug a USB1.1/USB2 keyboard and mouse in, everything else slows down. Again, I'm not yet worried about speeds. I'm worried that every external port show up connected to a USB2 hub. To me, that means that xHCI is calling one USB3 hub USB2 or something is not being identified correctly. USB3.1 I think explicitly addresses this issue saying that USB3 should always run at USB3 speeds, but vendors still seem to be churning out broken motherboards. > lsusb shows > Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub > Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub > Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub > Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub > > lsusb -t shows > /: Bus 04.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 5000M > /: Bus 03.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 480M > /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/4p, 1M > /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/10p, 480M > What I didn't post is the bits from dmesg that show that bus1 and bus2 are from PCI 00:03.0 Host bridge: Advanced Micro Devices, Inc.

Bus2 is clearly from the B350 chipset, and not actually available. Bus1 (10 ports even with the external hub not connected) seems like the 2 rear USB2 ports plus the two headers, plus four more ports apparently not actually available. If bus3 and bus4 are from the CPU, I don't think there should be any USB2. If they are from the Chipset, then were are the USB3 ports from the CPU? I am pretty sure the pairs of ports are linked. This seems to be a new development, and I'm not really sure what it means yet.

In the first instance set 'SELINUX=permissive' in the selinux config and see if it works as expected.

[gentoo-user] SELinux issues
Questions regarding SELinux. Two of them actually. First is how the HECK to I get it enabled!? I compiled my kernel to support it, and I do not have the disabling line in my boot config. But after rebooting to the new kernel, getenforce says disabled. So why is it disabled and how do I enable it? Next, whenever I try to install a SELinux policy that portage missed during it's install (not many, but a couple) I get an error. I've already created a bug on this (https://bugs.gentoo.org/show_bug.cgi?id=744736), but I was wondering if anyone on the list had any ideas as to what's wrong.

It has to go in /usr/lib64 instead of /usr/lib. (You can read about multilib-strict in `man make.conf`)
