Re: USB problems with SP3
Any electrical device when first powered on experiences what is called
an "Inrush Current". This is a momentary spike that levels out. If your
PC's are four years old they both should have USB-2 and USB-1(.1)
controllers and hubs. Each controller and it's associated Hub(s) have a
bandwidth and power limitation. Hubs are limited to 500 mA's, it's this
value you're exceeding. What is important to know is whether the iPods
are USB2 or USB1 type devices. Also if they are USB-1 then you may
be able to re-allocate the loading of Hubs by moving other USB devices
to another USB Hub. This requires determining how USB devices are
connected with Device Manager and an alternate view. (Devices by
Connection, and expanding the Computer driver to reveal the PCI Bus,
then the USB Controller(s).
As to why this shows up after applying SP3, it's probably the drivers
for the system level USB components.
