You can [hardly any more] find some USB hubs, which allow ports to be 
powered on & off via software control. I'm using an older Linksys hub 
(http://a.co/gPhfi45) and the following little loop to reset the USB 
when there is a problem:

root at odroid:~/bin# cat check_ups.sh
#!/bin/bash

while true
do
     x=$(curl -s -o - 
'http://192.168.1.5:85/cgi-bin/nut/upsstats.cgi?host=tripplite@127.0.0.1:3493' 
| sed  's:<[^>]*>::g' | awk 'BEGIN {s = 0; } $1 == "Status:" { s = 1; 
next; } s == 1 { print $0; s = 0; }')
     if [ "$x" != "ONLINE" ]
     then
         logger -p daemon.warning "Triplite is not offline, trying to 
restart USB"
         /root/bin/hub-ctrl -b 001 -d 005 -P 1 -p 0
         sleep 5
         /root/bin/hub-ctrl -b 001 -d 005 -P 1 -p 1
         sleep 30
     else
         sleep 300
     fi
done


(https://github.com/codazoda/hub-ctrl.c is the little USB power switch 
helper)

Hope, that helps a bit;-)
