hello guys. Im having some problems passing through a USB pcie card (http://www.amazon.com/gp/product/B00FPIMICA?psc=1&redirect=true&ref_=oh_aui_detailpage_o01_s00) i have attached a usb bluetooth device in the pcie card that i want to passthrough and it shows that is in bus 003: Bus 003 Device 003: ID 0a5c:2198 Broadcom Corp. Bluetooth 3.0 Device this is the result from readlink /sys/bus/usb/devices/usbX root@Tower:~# readlink /sys/bus/usb/devices/usb1 ../../../devices/pci0000:00/0000:00:14.0/usb1 root@Tower:~# readlink /sys/bus/usb/devices/usb2 ../../../devices/pci0000:00/0000:00:14.0/usb2 root@Tower:~# readlink /sys/bus/usb/devices/usb3 ../../../devices/pci0000:00/0000:00:1c.3/0000:04:00.0/0000:05:05.0/0000:08:00.0/usb3 root@Tower:~# readlink /sys/bus/usb/devices/usb4 ../../../devices/pci0000:00/0000:00:1c.3/0000:04:00.0/0000:05:05.0/0000:08:00.0/usb4 root@Tower:~# readlink /sys/bus/usb/devices/usb5 ../../../devices/pci0000:00/0000:00:1c.6/0000:0a:00.0/usb5 root@Tower:~# readlink /sys/bus/usb/devices/usb6 ../../../devices/pci0000:00/0000:00:1c.6/0000:0a:00.0/usb6 root@Tower:~# readlink /sys/bus/usb/devices/usb7 ../../../devices/pci0000:00/0000:00:1a.0/usb7 root@Tower:~# readlink /sys/bus/usb/devices/usb8 ../../../devices/pci0000:00/0000:00:1d.0/usb8 this is the IOMMU Groups: /sys/kernel/iommu_groups/0/devices/0000:00:00.0 /sys/kernel/iommu_groups/1/devices/0000:00:01.0 /sys/kernel/iommu_groups/1/devices/0000:01:00.0 /sys/kernel/iommu_groups/1/devices/0000:01:00.1 /sys/kernel/iommu_groups/2/devices/0000:00:14.0 /sys/kernel/iommu_groups/3/devices/0000:00:16.0 /sys/kernel/iommu_groups/4/devices/0000:00:19.0 /sys/kernel/iommu_groups/5/devices/0000:00:1a.0 /sys/kernel/iommu_groups/6/devices/0000:00:1b.0 /sys/kernel/iommu_groups/7/devices/0000:00:1c.0 /sys/kernel/iommu_groups/7/devices/0000:00:1c.2 /sys/kernel/iommu_groups/7/devices/0000:00:1c.3 /sys/kernel/iommu_groups/7/devices/0000:00:1c.6 /sys/kernel/iommu_groups/7/devices/0000:03:00.0 /sys/kernel/iommu_groups/7/devices/0000:04:00.0 /sys/kernel/iommu_groups/7/devices/0000:05:01.0 /sys/kernel/iommu_groups/7/devices/0000:05:03.0 /sys/kernel/iommu_groups/7/devices/0000:05:05.0 /sys/kernel/iommu_groups/7/devices/0000:05:07.0 /sys/kernel/iommu_groups/7/devices/0000:07:00.0 /sys/kernel/iommu_groups/7/devices/0000:08:00.0 /sys/kernel/iommu_groups/7/devices/0000:09:00.0 /sys/kernel/iommu_groups/7/devices/0000:0a:00.0 /sys/kernel/iommu_groups/8/devices/0000:00:1d.0 /sys/kernel/iommu_groups/9/devices/0000:00:1f.0 /sys/kernel/iommu_groups/9/devices/0000:00:1f.2 /sys/kernel/iommu_groups/9/devices/0000:00:1f.3 and this is the list of devices that i currently have on my unraid build (taken from system devices) 00:00.0 Host bridge: Intel Corporation 4th Gen Core Processor DRAM Controller (rev 06) 00:01.0 PCI bridge: Intel Corporation Xeon E3-1200 v3/4th Gen Core Processor PCI Express x16 Controller (rev 06) 00:14.0 USB controller: Intel Corporation 9 Series Chipset Family USB xHCI Controller 00:16.0 Communication controller: Intel Corporation 9 Series Chipset Family ME Interface #1 00:19.0 Ethernet controller: Intel Corporation Ethernet Connection (2) I218-V 00:1a.0 USB controller: Intel Corporation 9 Series Chipset Family USB EHCI Controller #2 00:1b.0 Audio device: Intel Corporation 9 Series Chipset Family HD Audio Controller 00:1c.0 PCI bridge: Intel Corporation 9 Series Chipset Family PCI Express Root Port 1 (rev d0) 00:1c.2 PCI bridge: Intel Corporation 9 Series Chipset Family PCI Express Root Port 3 (rev d0) 00:1c.3 PCI bridge: Intel Corporation 9 Series Chipset Family PCI Express Root Port 4 (rev d0) 00:1c.6 PCI bridge: Intel Corporation 9 Series Chipset Family PCI Express Root Port 7 (rev d0) 00:1d.0 USB controller: Intel Corporation 9 Series Chipset Family USB EHCI Controller #1 00:1f.0 ISA bridge: Intel Corporation 9 Series Chipset Family Z97 LPC Controller 00:1f.2 SATA controller: Intel Corporation 9 Series Chipset Family SATA Controller [AHCI Mode] 00:1f.3 SMBus: Intel Corporation 9 Series Chipset Family SMBus Controller 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc.

ASM1042A USB 3.0 Host Controller my 2 main questions are: 1- do i need to passthrough all the devices currently on group 7? if so, how do i make sure that all those devices are not critically importat for unraid to properly work? (my unraid usb is on bus 001) 2- which one is the right address for my bus 003? (as it shows ../../../devices/pci0000:00/0000:00:1c.3/0000:04:00.0/0000:05:05.0/0000:08:00.0/usb3) PD: I'm passing it through to use it with El Capitan Virtual Machine. thanks in advance for any help that can be provided. suggestions and/or corrections are very welcome. Edit: I have figured it out. First I had to enable the option "PCIe ACS Override" on VM Manager under settings. Second, I was using the wrong method to Pass it through because I'm using this method in a q35 machine (Mac OS X El Capitan). I was using the Hostdev method and I needed to use the qemu:arg method. Wrong (Hostdev method): <hostdev mode='subsystem' type='pci' managed='yes'> <driver name='vfio'/> <source> <address domain='0x0000' bus='0x08' slot='0x00' function='0x0'/> </source> </hostdev> Right (qemu:arg method): <qemu:arg value='-device'/> <qemu:arg value='vfio-pci,host=08:00.0,bus=root.1,addr=00.1'/> Note that the addr=00.1 because in the addr=00.0 i have my GPU passed through. Is now working like a charm. Hope it can help somebody.
