Drivers¶
The primary driver for all Ettus Research products - including the USRP1 - is UHD, the Universal Hardware Driver. UHD software is considered stable and is actively maintained by Ettus Research. The UHD driver is recommended for nearly all users.
The second, older driver is contained within GNU Radio and compiled as the separate library, libusrp, which is no longer actively maintained. With a few exceptions, legacy driver users should upgrade to UHD.
