Resetting usb devices/hubs from command line

To reset "hung" usb device (ie to simulate unplugging and replugging it) I use nice program usbreset. It can be downloaded from GitHub (and I suppose from many other places). After compiling (gcc usbreset.c -o usbreset) it is ready to use.

For mass-resseting usb devices I use this small script:

#!/bin/bash

for d in `find /dev/bus/usb/ -type c`
do
    echo $d
    /usr/local/bin/usbreset $d
done
