I don't know if this is what you're looking for, but I have indeed
problems getting USB to work on my new notebook. Some info: Asus P8300,
500MHz Celeron, 128MB, Intel 440MX chipset. Here is the output from
"lspci -vvx":

As a sidenote: I am able to use a 3Com Megahertz 574B when I run

is detected as a memory card and fails to initialise.

Let me know if you want more information.
