Confirmed by the first link in a Google search for "D830" and "USB2":

And does it match the lspci on the above webpage?

You could also have a look through /var/log/dmesg for messages to do
with USB, ohci (the Open Host Controller Interface, for USB 1.1) and
ehci (Enhanced Host Controller Interface, for USB 2.0).


As for Ubuntu 11.10 and other distributions not supporting USB 1.1,
I think Christopher needs to say where he got that idea. It's not
something I've ever met or heard of. There may be *particular*
USB 1.1 devices that are not supported, such as those that require
firmware to be uploaded. That should not include USB drives.
