Subject: UmTRX uhd_usrp_probe command "holler protocol" error




I have been following the instructions at
work-on-the-raspberry-pi-2) but have encountered a strange error when I run
the "uhd_usrp_probe" command, stating:



linux; GNU C++ version 4.6.3; Boost_105000; UHD_003.008.002-151-gbf4f50de


-- Opening a UmTRX device...

Error: RuntimeError: NotImplementedError: holler protocol not implemented



I have done a search on Google for the error but there doesn't seem to be
any information on it. 


Do you have any idea what is causing it? Any help would be much appreciated.


Should you be interested in knowing the exact commands I ran when following
the instructions, let me know and I'll write them out.
