Unfortunately, USB devices are not easily represented in the standard
Unix way where one physical device maps to one /dev node. The first
Linux hiddev driver couldn't cope with the complexity of the USB HID
reports coming in from UPSes (and the hiddev API is Linux-specific),
so NUT uses libusb directly (which uses /dev/bus/usb nodes instead of

We have a couple of outstanding email threads about apparently
spurious "Device or resource busy" messages, but to my knowledge, none
of the NUT developers own a device which is exhibiting this problem.
