Paul, have you unchecked the option to allow the computer to turn the USB
port off to save power? You'll find this on your computer's Device
Management, Power Management tab on the USB HUB device.

This should be on Device Manager. Windows 98 Second Edition should be stable
enough, but...

Is this a brand computer (like HP, Dell, Gateway), or another type? Is the
motherboard based on a VIA Chipset, and how old is it?

It's not an icon... It's a tab

Open device manager, find the Universal Serial Bus Controlers [+], and drill
down to USB Root Hub. You should see a tab Power Management. There's a
checkbox "Allow the computer to turn off this device to save power".

However, bad news. Old VIA chipsets had lots of problems with Bluetooth.
This is around 2000/2001. Check this thread:

Found USB Root Hub. Properties provided a Power tab. Power tab has one
button (other than OK or Cancel) titled "Power Properties". This button
provides a list of devices on the hub, one of which is my "Dell Axim USB
Sync". There are no checkboxes. Right clicking that item provides
nothing. No need in beating it to death. It ain't there. However,
thanks for the guidance.
