[CentOS] USB blues

[Billy Crook]

Sounds very much like an electrical supply problem.  Does it ever affect
host-powered peripherals or just ones powered off AC mains?  Are you using
a UPS?

Try an alternate psu in the system.  or running on just one psu module at a
time if you have redundant modules.  This system isn't a bulk storage
system with tonnes of hdds, is it?

You mention the lspci and lsusb you included earlier were taken AFTER the
problem.  What differences are there immediately after a fresh boot before
the problem occurs. add -t to lsusb.
