Dan, I think you were working a different, USB-related issues.
My task is a bit different. The goal is not to power cycle the USRPs - its to re-initialize and resume after and power cycle, without intervention from an external executive or operator. (ie. by some task that monitors for a stop in dataflow and then perhaps calls a re-init function in gr-uhd, or rebuilds a flowgraph entirely) -John On Wed, Feb 18, 2015 at 3:06 PM, Dan CaJacob <dan.caja...@gmail.com> wrote: > I worked around a problem like this by installing an in-line power relay > in my remote nodes.
