Hi,
We have a remote station with an USRP B210.
We observed that sometimes the remote machine cannot find the USRP
B210 (I think it has to do with uncontrolled power cycles, but I am
not 100% sure about the root cause. The point is that sometimes it
happens).
The only way to sort it out is to disconnect the power supply and the
USB cable from the USRP, and then the remote machine can detect it
again. i.e. doing a complete power reboot to the USRP.
It is not a killer because the problem is not always happening, but it
is annoying because it implies sending somebody to disconnect and
connect the USRP B210 cables.
Is anybody experiencing a similar issue? Any idea how to fix it?
The remote machine uses Ubuntu 22.04.3 LTS and the UHD drivers.
Thanks!
Fran
I've seen this sporadically with B2xx over the years I've been using
them. For example, on some hardware, the system cannot
see the device on reboot, and you have to replug/power-cycle for the
system to even see it.
When this happens, does it show up in "lsusb" ?
