 Posted: Sat Aug 04, 2018 1:40 pm Post subject: realtek usb ethernet and udev [SOLVED] |
 |
|
I have a realtek 8153 usb ethernet adapter which works fine
except if it autosuspends. Then it wreaks havoc.
I added a rule called 10-usb-realtek-ethernet-r8153.rules
to /etc/udev/rules.d which looks like this:
| Code: |
ACTION=="add", SUBSYSTEM=="usb", ATTRS{idVendor}=="0bda", ATTR{idProduct}=="8153", TEST=="power/control", ATTR{power/control}="on" |
but (even after reboot or unplugging/replugging device) I find that
| Code: | | cat /sys/bus/usb/devices/usb2/2-1/power/control |
is still "auto" instead of what I want which is "on"
Is there something wrong with my rule (I have double checked idVendor and idProduct
and they are correct)?

never seen someone using / in the attribute name, did you have really check that "power/control" do exists?
you could query all attributes with
| Code: | | udevadm info -qall --attribute-walk /sys/class/net/name_of_the_device |
and you can see if your rule is working properly with
| Code: | | udevadm test /sys/class/net/name_of_the_device |

thanks Krinn; yes "power/control" is not in ATTR (I found
the rule on the internet somewhere  )
But the problem was stemming from TLP; my rule would
not counteract its udev control (I asked for a script to
run in my new udev rule but TLP overrode it).
I found out you can force TLP to disable autosuspend for
particular devices, so now everything works as it should
