usb networking adapter problem and replunging adapter doesn't reconnect networking.

[shisui]

I have been struggling with networking problems for a long time.

Since the on-board NIC only supports 100M, so I bought a 2.5G usb nic with a r8156 chipset.

However, after an update, the network will randomly disconnect, and I must restart the device or the networking service.

my networking configuration:

auto lo
iface lo inet loopback

auto enp1s0
auto enx00e04c681128

auto vmbr0
iface vmbr0 inet static
        address 192.168.8.254/24
        gateway 192.168.8.1
        bridge-ports enx00e04c681128
        bridge-stp off
        bridge-fd 0
        bridge-vlan-aware yes
        bridge-vids 2-4094

I checked the logs and found the adapter was disconnected, enx00e04c681128 is the name of NIC.

then I found this:

xhci_hcd 0000:00:14.0: WARN Set TR Deq Ptr cmd failed due to incorrect slot or ep state

xhci_hcd 0000:15:00.0: WARN Set TR Deq Ptr cmd failed due to incorrect slot or ep state

A kernel bug.

After the network adapter reconnected, the networking still does not work until I restart the networking service.

And replunging network cable doesn't reconnect networking.

I wonder if there is any solution.
Thanks in advance.

update, add

iface enx00e04c681128 inet manual

, so far so good.
