If there are users out there having trouble with USB hubs connecting / disconnecting, I think the solution may be to purchase a dedicated USB card instead of using the ports built into their keyboards. Here's my experience:

I purchased a Mobility Easidock USB 200 - a 5 port USB hub with USB to serial, USB to parallel, USB to PS/2 mouse and USB to PS/2 keyboard built in. Really a very good deal for what you get, selling for $20-$30 on E-bay. I hooked up my USB Intellimouse explorer, scanner, and APC BackUPS Office USB. I had problems with the mouse and UPS constantly registering "disconnect/reconnect" sounds on my computer in Windows XP. Eventually, the hub would bug out and stop working until I rebooted the system. I tried all of the suggestions on this website, but to no avail. So I gave up on the hub, and decided to purchase a USB 2.0 PCI card with 5 ports (4+1). I got a great deal - $22 including shipping for a retail name-brand card on Ubid.com. I installed the card today and hooked up all of the peripheral - amazingly, they all worked! Then I hooked up all the peripherals to the Easidock hub, and connected the hub to the USB card. Surprise - it still worked!

What I think must be happening is that the hub doesn't like the USB ports built into the keyboard. I did notice that the disconnect / reconnect occurred more often in CPU-intensive activities such as watching AVI's or playing MP3s. Perhaps you guys with the 2 Ghz CPUs aren't having any problems with USB hubs. I only have a 400 mhz celeron on an old Abit LX6.

In summary, if you have a slow computer like me, and you're having trouble with your USB hub, try using a dedicated USB PCI card.

Good luck,
Eric
