Because programs written for UHD and and raw ethernet drivers are not
compatible with each other.

usrp2_probe works only with raw ethernet drivers while uhd_find_devices
works only when UHD is on your SD card.

In case of UHD thing on your SD card the uhd_fft.py shd work fine.

If you are using TVRX daughter board then only UHD support is there for it.

What error messages are you getting.
