benchmark_tx uses the old USRP2 driver, not the UHD driver.

Installed UHD following instructions from here:

GNU Radio was checked out from git master, so it is 3.3.1. Installed without
error.
After setting up PC IP, I am able to ping usrp2. Both uhd_find_devices and
uhd_usrp_probe work, results are in the end.
However, when I run sudo benchmark_tx.py, USRP2 (with WBX daughterboard) could
not be found, results are next below.
Any hints will be highly appreciated. I reinstalled both UHD and GNU Radio one
time, same story. I tried to set options of -u, -a, and -e when running
benchmark_tx.py, same story.
