Anyone can help me?
The usb address changed automatically:

this works well:
01:1b.0) hub
|__2-1 0bda:8156:3000 00 3.20 5000MBit/s 512mA 1IF (Realtek USB 10/100/1G/2.5G LAN 000000001)

but this not work:
01:1b.0) hub
|__2-1 0bda:8151:3000 00 3.20 5000MBit/s 512mA 1IF (Realtek USB 10/100/1G/2.5G LAN 000000001)

How could I make it use fixed device ID? And sometimes it changed back as 0bda:8156, but my VM cannot use it again.
