James and Tom,

I thought I found a Bargain the other day.

I was over in Louisville, KY. in a store and went directly to the
Clearance Section (after I asked where to find it) and saw a 4 port
Powered USB Hub for US$9.95.

Boy!, was I chomping at the bit to take that item off the hook it was
hanging on.

Then I saw it was just a USB 1.1 hub and put it back.

I use a 4 port Powered USB hub on my notebook.

I have 2 Powered USB hubs on my desktop, a 4 port and a 7 port.

On the desktop once in a while I will Scan the HD in the XP box,
the two external usb HDs and all 6 of my thumbdrives for Virus(es).

I got a couple 2 GB thumbdrives that are fatter than most thumbdrives
are, so I can't use the port next to them to connect another USB thingy.
