I am having trouble passing through a USB controller on my motherboard:
IOMMU group 15:[14e4:43b1] 04:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4352 802.11ac Wireless Network Adapter (rev 03)
IOMMU group 16:[1b21:2142] 05:00.0 USB controller: ASMedia Technology Inc. ASM2142 USB 3.1 Host Controller
IOMMU group 17:[144d:a804] 06:00.0 Non-Volatile memory controller: Samsung Electronics Co Ltd NVMe SSD Controller SM961/PM961
I have already added the vfio line on the syslinux.cfg file:
append vfio-pci.ids=1b21:2142 pcie_acs_override=downstream,multifunction vfio_iommu_type1.allow_unsafe_interrupts=1 initrd=/bzroot,/bzroot-gui
I can already see it on the VM template (screenshot attached).
But when i tick it to include in the passthrough, my windows 10 VM is stuck at the TIANOCORE splash screen.
