My computer keeps telling me to Add a USB Hi - Speed controller to the
computer.

Also when I use a hub it tells me that the hub exceeds the power limits of
its hub port.

I need the Hub for printer, memory sticks, cameras, dud/ cd burner.

Can anyone advise as to what I need to do or can do.

Thanks
 
You need a USB 2.0 powered hub.

Nope, its got its own power and doesn't need connect/disconnection on
regular basis. Onboard USB port is fine. May be powered on prior to
booting XP.

memory sticks,

"memory sticks" plug directly into the USB port. Low power usage. Fine
plugged into an onboard USB port. Does need connect/disconnect physical
availability. A front mounted USB interface usually is best with a PC using
these. Device should not be left in USB port when not in use. Removable
media should be removed when not in use.

cameras,

Usually plugs directly into the USB port. Relies on the camera power for
both operability and interface communication. PC sees nothing until the
camera is turned on. A front mounted USB port/ports interface works best on
a PC when using this. Should be disconnected physically when not in use.

dud/ cd burner.

Enclosure for these may or may not be self powered. If not, a powered hub
may be required. Turn the device off when not in use if self-powered. Get
a self-powered enclosure model if you have the funds.

A USB 2.0 or USB high speed controller is most likely attributed to the
dvd/cd burner throughput availability. Or "memory stick" as well. This is
not a hub.

If this is a laptop vs. a PC, there are variances in some of my replies
above as result. Am assuming you have a PC.
 
Things to check:

1) In Device Management (Device Manager), make sue that you have an "enhanced"
USB controller. This indicates that you really have USB 2.0 ports. If not,
you can add a PCI USB 2.0 adapter (you can not upgrade USB 1.0 / 1.1 ports to
USB 2.0) or check in the BIOS to see if the USB 2.0 feature is active.

2) USB hub must have its own power adapter and it needs to be plugged into a
power outlet.

3) You must have motherboard chipset drivers installed and any USB filter
drivers (VIA chipset????) installed.

4) Try with only the USB hub connected. Then, connect one device at a time,
until the message returns. If it returns, then you might need to add
additional powered hubs. You can add the extra hubs to the existing hubs
(known as 'daisy-chaining'.)
