UHD showing duplicate device for USRP X310

junkyardhokie commented 9 months ago

Bug Description

The uhd library is reporting a duplicate device for the USRP X310. There should only be a total of two radios reported, (1) USRP X310 and (1) USRP E310. The X310 does have two UBX160 daughterboards.

A simple program to discover the devices shows three devices:
