"upsd" is just one of several components of NUT. The "No such file or directory" refers to the Unix domain socket that the NUT driver creates. The nut-server init script in the Debian package will start the driver, upsd, and upsmon. (You also don't need the "-u root" flag if the /dev node is already in the NUT group.) Please try again and let us know how it works (051d:0002 devices should be supported by NUT).

Thanks for providing the Linux distribution and NUT version info.
