Hi, I'm wondering if/how I can control a B2xx device from an N310. I use the B2xx as an LO for shared LO operations from an N310. Presently, I use a laptop to control my B200mini, but I am wondering if this control can be done directly from the N310. I realize that the N310 USB port is not USB3 but since my streaming rates for a CW tone are as slow as possible, hopefully that won't matter. I have connected the B200mini to the N310 USB port, but I can't see the B200mini when I run uhd_find_devices. I have copied the B2xx FPGA images to the /usr/share/uhd/images/ folder and I have copied the file uhd-usrp.rules to the /etc/udev/rules.d/ folder and rebooted the N310, but still no luck. The following is the output of the "lsusb" and "uhd_find_devices" commands. The "lsusb" command shows the presence of the Cypress device, but the device is still not found. Suggestions?

Update. I realized that the default UHD build on the N310 might not include support for USB or B200. I confirmed this by running "uhd_config_info --enabled-components". I then attempted to build UHD on the N310 (directly on device rather than cross-compile) and after installing Mako (pip3 install Mako) and ruamel.yaml (pip3 install ruamel.yaml) I was able to run cmake and then "make -j2". Unfortunately, the build did not complete (see error below). Note that below this error message I also provided the cmake command I used along with its output. Any suggestions for this error?
