I am trying to monitor a boat load of UPSes off a soekris 5501 (same error on 
an Alix box) and a pair of USB hubs. It seems I can only have one USB hub plug 
in at a time. If I plug just one in, all is ok. But if two are plugged in, I 
get a stream of errors like this. Is this some sort of device or driver 
limitation ?
