UHD, the "Universal Software Radio Peripheral" hardware driver on Debian: ========================================================================= usrp group ---------- The Debian uhd-host package installs a usrp group. This provides two main benefits: - Access control: The udev rules limit access to members of the group (at least for USB attached USRPs). - Real Time Priority priviledge: The pam limits setting allows UHD to boost the thread scheduling priority for usrp group members. To avail yourself of these benefits, add your username to the usrp group, perhaps by running, as root something like: adduser myusername usrp substituting your user name for myusername. Settings will not take effect until the user has logged in and out. Multiple packages ----------------- uhd-host: The uhd-host package contains the uhd_find_devices and uhd_usrp_probe commands for locating and examining USRP devices available to the host system. Also, under /usr/lib/uhd/ are examples, tests and utils directories. The utils include tools for managing the flash memory or EEPROM configuration of various USRPs. libuhd003: Small package just for the library itself. libuhd-dev: Small package just for developing applications using the library itself. uhd-images: The uhd-images package is not part of the main Debian distribution because the FPGA firmware requires non-free vendor tools to compile from source. Look for it in Debian's contrib packages area. For USRP devices with non-volatile configuration having the firmware images on the host is optional. But some USRPs are volatile, and the UHD library will fetch files from the /usr/share/uhd/images/ directory at runtime. The uhd_install_frmware program in uhd-host also helps manage these files.
