Hi,When I executed the "uhd_find_devices"I got "[ERROR] [USB] USB open failed:
insufficient permissions."However, when I put sudo in it(i.e. sudo
uhd_find_devices", there is no such error.Also, when I typed "./tx_waveforms
..."I got an following WARNING"[WARNING] [UHD] Unable to set the thread
priority. Performance may be negatively affected.Please see the general
application notes in the manual for instructions.EnvironmentError: OSError:
error in pthread_setschedparam"similarly, the warning disappeared when I put
the sudo in it.Marcus said it is incomplete installation, if the sudo needed.As
Marcus recommended, I created(because there was no such file)
/etc/udev/rules.d/10-usrp.rules and put the following contents.## Copyright
