[Eaton5E]
driver = blazer_usb
port = auto
$ upsdrvctl start对于usbhid-ups驱动程序的结果：
Network UPS Tools - UPS driver controller 2.4.3
Network UPS Tools - Generic HID driver 0.34 (2.4.3)
USB communication driver 0.31
No matching HID UPS found
Driver failed to start (exit status=1)
$ upsdrvctl start对于blazer_usb驱动程序的结果：
Network UPS Tools - UPS driver controller 2.4.3
Network UPS Tools - Megatec/Q1 protocol USB driver 0.03 (2.4.3)
No supported devices found. Please check your device availability with 'lsusb'
and make sure you have an up-to-date version of NUT. If this does not help,
try running the driver with at least 'subdriver', 'vendorid' and 'productid'
options specified. Please refer to the man page for details about these options
(man 8 blazer).

编辑/etc/nut/ups.conf，并为UPS设备本身添加部分：

答案2
根据第在NUT上为Eaton 3S UPS配置Ubuntu Linux，在/etc/nut/ups.conf中，你应该使用驱动程序usbhid ups而不是blazer_usb，还要确保MODE=standalone在/etc/nut/nut.conf中。
答案3
可以使用lsusb查找总线和设备号
然后更改设备的权限
chmod 0666 /dev/bus/usb/[bus number]/[device number]
