My computer has the 4 USB ports used. I tried two different AC powered
USB hubs and they do not show up in XP SP3..

Anyone knows why a USB hub doesn't show up but any device connected to
a built-in USB port works fine?

Are you looking in the right place ?
Device manager --> Universal Serial Bus Controllers --> USB Root Hub

Examine the above. Remove the HUB from the PC and see if the PC's device list changes.

Where do you think they should show?

You're saying that nothing connected to the hubs works?

You don't state WHERE the hub doesn't show up, so I'll assume Device
Manager.

If you are talking about a USB Hub that you connect to a USB Port on
your system, they do not show up in Device Manager.

USB Hubs just turn a single USB Port on your system to use multiple
ports on the hub. I know because I HAD a Kingston USB 4-Port Hub.


Now, if you meant that the hub does not show under Safely Remove
Hardware, that MAY be a problem depending on how the hub works. I'm
do not remember if my Kingston showed up there.


The question is, do the USB Ports on your hub work? If they do, no
problem.


The only other question, the Kingston was a USB2 device so my system
had to support USB2. Does Device Manager, Universal Serial Bus
Controllers, list USB2 or "Enhanced" Host Controllers?

If NOT, check your BIOS Setup and see if your motherboard has USB2
support and that it's enabled. If your motherboard DOES support USB2
but Device Manager does NOT have USB2 drivers, you need to install
them. Note I had an experience with 2 Dell systems at work, where
they DID support USB2 but Dell forgot to install USB2 drivers. Ended
up going to Intel (the Dells used the Intel Chipset) and getting the
latest chipset drivers from them.
