[srslte-users] srsenb failed to find device

I use USRP B210, and srsenb fails to find the device once for a while after execution.

My approach is to write a script to soft-reset my USB 3.
Works most of the time, if this fails, the final approach is to unplug the device and plug it again.

I think soon or later this should be enlisted as an issue for the devs to solve.

> Resetusb.sh

#!/bin/bash
for i in /sys/bus/pci/drivers/xhci_hcd/*:*; do
  [ -e "$i" ] || continue
  echo "${i##*/}" > "${i%/*}/unbind"
  echo "${i##*/}" > "${i%/*}/bind"
done

Hey,

for the X310, also add "type=x300" to the device args.

Hope that helps.

Cheers
Andre
