Title:
rtl8156B loaded with wrong driver and not working
Status in linux package in Ubuntu:
Incomplete
Bug description:
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
