[USRP-users] Cannot find usrp e310 with uhd_find_devices

Dear Ivan,

the E310 is not designed to work as a peripheral to a PC, but is its own
embedded computer, integrating a USRP. You'd normally run your signal
processing applications, for example GNU Radio, on the E310 itself
rather than on a separate PC.
Thus, E310 can't be detected by uhd_find_devices.

You can try the network_mode [1] on the E310, but it's really just a
diagnostic tool, and delivers only very small sampling rates.

Best regards,
Marcus Müller
