如何固定USB设备的Bus和Device序号

[taotaoya]

你好，我在使用PVE 8.2，我通过添加Device Passthrough给CT容器直通USB设备，/dev/bus/usb/001/003
一切都能正常使用，但是当USB设备重新插拔以后，他的Device序号就变了，会导致我䰊该设备，请问如何固定USB设备的BUS和Device序号呢？

You have to set up a permanent path yourself.

Check lsusb which one is your device, then look for its particulars with udevadm info -a -n, create a new rules file in /etc/udev/rules.d that maps it:

SUBSYSTEM=="usb", ATTRS{idVendor}=="XXX", ATTRS{idProduct}=="YYY", ATTRS{serial}=="ZZZ", SYMLINK+="mydevice"
