Is there a way to ask fedora what
kind of USB ports it thinks it has?
Preferably before plugging something into one.


   $ /sbin/lspci



Thanks.
Anyone know whether
00:07.2 USB Controller: VIA Technologies, Inc. UHCI USB (rev 11)
is USB 1 or 2?
Google hasn't helped.


Which VIA chipset do you have?

UHCI is USB 1
EHCI is USB 2

John
