usbdevsource not work

[mayost]

Hello to you

I've tried versions: 6.0.14, 6.1.0_BETA2

I have two Linux computers

1. VirtualBox on Linux Hosts which Windows 10 Guests (name: win10)
2. Linux Hosts USBIP (IP address 192.168.30.210)

I tried running the usbdevsource option on Linux VM host like this:

VBoxManage usbdevsource add "13fd: 3e40" --backend "usbip" --address 192.168.30.210

When I run Linux, the VM hosts the command:

VBoxManage list usbhost

I can see that he recognized the USB connected to a LinuxIP host well, it looks like this:

UUID:               00a5dccb-745f-44fd-85ec-549d16b7eb0e
VendorId:           0x13fd (13FD)
ProductId:          0x3e40 (3E40)
Revision:           16.96 (1696)
Port:               2
USB version/speed:  3/Super
Manufacturer:       Initio Corporation
Address:            usbip://192.168.30.210: 3240: 2-3.1
Current State:      Busy

But when I make:

VBoxManage controlvm win10 usbattach 00a5dccb-745f-44fd-85ec-549d16b7eb0e

I see Windows 10 Guests the USB device detected for a few seconds and gone

And when I run again:

VBoxManage list usbhost

I can see that the USB UUID has changed

Is it a bug?

First, thank you so much for your editing.

I forgot to mention that my host is:
Fedora 30 64BIT
OR
Fedora 31 64BIT
In both hosts, for testing I disabled FIREWALL AND SELINUX

Later I will attach the log file

I need to test this as well, I've been meaning to test remote USB for the longest time, maybe this is the "catalyst" I was looking for...
