Hi,
Here is some more info - the output from "lsusb" and from the GTK app USB
viwer - I appologize if there is some duplication of information here, but
being pretty new to USB I'm not sure what exactly it all means:
lsusb produces:

USB Viewer lists only a USB UHCI Root, with this info:

I also just recompiled the kernel to put the USB support directly in, and
also enabled the verbose USB debugging messages. Now in /var/log/messages
I find:

.......etc - this last sequence of messages goes on for many more lines.
Again, let me know if you need more info.
