I have a usb-network-adapter Realtek rtl8153 and Ubuntu 24.10 / 6.11.0.9.

uname -a            
Linux *** 6.11.0-9-generic #9-Ubuntu SMP PREEMPT_DYNAMIC Mon Oct 14 13:19:59 UTC 2024 x86_64 x86_64 x86_64 GNU/Linux

lsb_release -r
Release:    24.10

When I connect the USB adapter without network cable, I can see it in lsusb and in dmesg:

lsusb
Bus 004 Device 011: ID 0bda:8153 Realtek Semiconductor Corp. RTL8153 Gigabit Ethernet Adapter

dmesg

[ 4223.450639] r8152 4-2:1.0 enx00e04c680013: renamed from eth0

But when I connect a network cable, I see:

[ 4917.636729] r8152-cfgselector 4-2: USB disconnect, device number 11

[ 4922.085161] usb usb4-port2: Cannot enable. Maybe the USB cable is bad?

and the device disappears from lsusb | grep 8153.

Rarely everything just works, for example after reboot if I reconnect the adapter 3-5 times, it starts sometimes working.

Can you please advice in which direction should I look to find the root cause for this problem?

I know I'm a little late, but I had the exact same issues and traced it to being triggered only when plugging in an Ethernet cable.

I disabled usb autosuspend in the kernel and it has been fine since.

I added usbcore.autosuspend=-1 to GRUB_CMDLINE_LINUX_DEFAULT= in /etc/default/grub - this method disables usb powersaving/autosuspend globally so might not be right for everyone.
