USB controller issue

[Prox815]

I want to pass through a of the USB controllers to my VM. My PC has USB 2.0, USB 3.0 and USB type C interfaces. Which of the following are USB controllers?

root@pve:~# lspci|grep controller
00:02.0 Display controller: Intel Corporation CometLake-S GT2 [UHD Graphics 630] (rev 05)
00:12.0 Signal processing controller: Intel Corporation Comet Lake PCH Thermal Controller
00:14.0 USB controller: Intel Corporation Comet Lake USB 3.1 xHCI Host Controller
00:16.0 Communication controller: Intel Corporation Comet Lake HECI Controller
00:17.0 SATA controller: Intel Corporation Device 06d2
00:1f.5 Serial bus controller [0c80]: Intel Corporation Comet Lake PCH SPI Controller
03:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Navi 10 [Radeon RX 5600 OEM/5600 XT / 5700/5700 XT] (rev ca)
05:00.0 Network controller: Broadcom Inc. and subsidiaries BCM4360 802.11ac Wireless Network Adapter (rev 03)
06:00.0 Non-Volatile memory controller: Sandisk Corp WD Black SN750 / PC SN730 NVMe SSD
08:00.0 Ethernet controller: Intel Corporation Ethernet Controller I225-V (rev 02)
0a:00.0 Non-Volatile memory controller: Sandisk Corp WD Blue SN550 NVMe SSD (rev 01)

Are 00:14.0, 00:1f.5 the only 2 USB controllers?

Check your IOMMU groups with for d in /sys/kernel/iommu_groups/*/devices/*; do n=${d#*/iommu_groups/*}; n=${n%%/*}; printf 'IOMMU group %s ' "$n"; lspci -nns "${d##*/}"; done, to make sure you pass one that is alone (bridges don't count) in a group.
To me, it looks like you have only 1 USB controller: 00:14.0. The command above should give us more information about the type of 00:1f.5 (and its group).
