USB subsytem

[Trevor "TeC" Christian]

Good day all,

I have a FC3 web and file server. This server runs apcupsd and provides 
the network UPS communication interface.  I looking through my root mail 
this morning, i found that @ 4:43 this morning this server lost contact 
with the UPS directly connected to it via the USB port.  This setup was 
always working and a similar configuration is still currently working on 
another remote server.

I tried firstly restarting the service (apcupsd) the slave machines 
which had shown signs of being connected to the ups before now indicated 
that the communication was lost and successful restart of the service is 
yet to be achieved.  Checked the logs, did some googling, went to the 
support page for apcupsd which pointed me to the instructions and 
precautions i had to take when installing etc...

I tried unplugging and replugging the UPS even into different ports and got

appended to the /var/messages/log

I've considered restarting the system - but for fear of disruption would 
wonder if there is an alternative or a way to restarted the USB 
subsystem that keeps being mentioned in my google results?

Any thoughts, comments, suggestions are welcome...

Thank you
