Hello, I'm using nut for few days and found it working perfectly fine in most conditions. However, there is one behavior I am not able to handle correctly: When I boot my computer (I am in a mode=standalone configuration) while my UPS is not connected and that I plug it (using USB cable) later, the driver doesn't mount automatically, and I am not able to enable communication with my UPS. I need to restart nut-server.service to get communication established. Is there any way to make this hot plug works? My configuration: * Debian 11 * NUT 2.7.4-13 installed from apt-get * UPS: ECUS MRT_2_1000 running fine with blazer_usb driver * Regards, Maxence -------------- next part -------------- An HTML attachment was scrubbed...

Hi Bart,
Thanks for the clue.
I tried and managed to make it works by modifying the udev rule I was
working with.
Not sure if this is 100% correct but I can now recover my UPS when I
hotplug it:
/etc/udev/rules.d/ 90-nut-ups.rules
# ECUS UPS
ACTION=="add", SUBSYSTEM=="usb",
ATTR{idVendor}=="0001",
ATTR{idProduct}=="0000", MODE="0664", GROUP="nut",
RUN+="/usr/bin/systemctl restart nut-server.service"
Best regards,
Maxence

Hello,
I?m using nut for few days and found it working perfectly fine in most
conditions. However, there is one behavior I am not able to handle
correctly:
When I boot my computer (I am in a mode=standalone configuration) while my
UPS is not connected and that I plug it (using USB cable) later, the
driver doesn?t mount automatically, and I am not able to enable
communication with my UPS.
I need to restart nut-server.service to get communication established.
Is there any way to make this hot plug works?
My configuration:
* Debian 11
* NUT 2.7.4-13 installed from apt-get
* UPS: ECUS MRT_2_1000 running fine with blazer_usb driver

Maxence
