Покажу на примере сетёвки. С юсб всё аналогично.
Сначала с помощью lspci -nnk узнаёшь подробности об устройстве.
00:19.0 Ethernet controller [0200]: Intel Corporation Ethernet Connection (2) I218-V [8086:15a1] (rev 05)
DeviceName: Onboard LAN
Subsystem: Gigabyte Technology Co., Ltd Device [1458:e000]
Kernel driver in use: e1000e
Сначала отвязываешь устройство, используя цифры в самом начале и имя драйвера.
echo 0000:00:19.0 > /sys/bus/pci/drivers/e1000e/unbind
Далее привязываешь его к драйверу vfio-pci используя значения из квадратных скобок
echo "8086 15a1" > /sys/bus/pci/drivers/vfio-pci/new_id
После этого можно использовать это устройство в команде запуска виртуалки следующим образом:
qemu-system-x86_64 \
-name "Win10-min" \
-smp 12,cores=6,threads=2,sockets=1 -cpu host,kvm=off \
-machine accel=kvm \
-boot menu=on \
-rtc base=localtime \
-nic none \
-device virtio-gpu-pci \
-device vfio-pci,host=00:19.0 \
-device vfio-pci,host=00:1f.2 \
$*
-device vfio-pci,host=00:19.0 - это вот как раз проброс.
Но учитывать надо вот что. В выхлопе dmesg хоста должен быть похожий участок:

Обрати внимание, что в одну группу может попасть несколько устройств. Фишка в том, что их все следует как минимум отвязать от их хостовых драйверов перед пробросом, иначе проброс не заработает.
