Public bug reported: I have a 2.5G USB Ethernet dongle that use the Realtek 8156B chipset. The default driver being loaded are cdc_mbim and cdc_ncm, but this driver (cdc_ncm) is an incorrect driver that does not work with the chip. Instead, I have to manually load the r8152 driver to make it work; I cannot blacklist cdc_ncm as I am also using it with other devices.
Current Platform: Ubuntu 22.04.1, kernel 5.15.0-56-lowlatency Reproducible: always Expects: plugging in the USB dongle will have correct driver loaded, and just work Steps to fix: ----------------------------------- rmmod cdc_mbim rmmod cdc_ncm rmmod cdc_ether modprobe r8152 echo 0bda 8156 > /sys/bus/usb/drivers/r8152/new_id ----------------------------------- reference links: https://forum.manjaro.org/t/no-carrier-network-link-problem-with-usb-2-5-gbit-lan-adapter-realtek-rtl8156b-on-x86-64/97195 https://lore.kernel.org/netdev/20211227182124.5cbc0...@kicinski-fedora-pc1c0hjn.hsd1.ca.comcast.net/#t ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2000805 Title: rtl8156B loaded with wrong driver and not working Status in linux package in Ubuntu: New Bug description: I have a 2.5G USB Ethernet dongle that use the Realtek 8156B chipset.
