New set of questions! Yay!
I followed the instructions for Ubuntu on USB install and have the netbook booting from the USB. I get a screen with UBUNTU at the top, and has options of what to do: Try Ubuntu Netbook Remix with, Install Ubuntu Netbook Remix, Check disc for defects, Test memory, Boot from first hard disk, Advanced options, Help.
If I choose Try or Install, it goes to a black screen with a symbol that I'm pretty sure is the Ubuntu symbol. Then, it takes me to a black screen which seems to be an error message. I don't know what to do here. Lines like "can't open .dev.sdb: No medium found" and "can not mount /dev/loop1 on /cow" don't sound right. I'm left with a prompt and I think that it's asking me to mount a filesystem, but -a (which it tells me is "mount all filesystems in fstab) gets a reply of
"/bin/sh: -a: not found
(initramfs)"
Am I doing something wrong? The install guides I'm finding all seem to think that I'm past the hard part now that the USB is set up and being read. They all say to "follow the instructions" and "it's easy"...
I've tried setting up the usb drive again, and nothing changed. Any ideas what I can do here? Sorry for the huge message, I just don't know what's needed here and what isn't.

EHCI(4) BSD Kernel Interfaces Manual EHCI(4)
NAME
ehci -- USB Enhanced Host Controller driver
SYNOPSIS
device ehci
DESCRIPTION
The ehci driver provides support for the USB Enhanced Host Controller Interface, which is used by USB 2.0 controllers.
EHCI controllers are peculiar in that they can only handle the USB 2.0 protocol. This means that they normally have one or more companion
controllers (i.e., ohci(4) or uhci(4)) handling USB 1.x devices. Consequently each USB connector is electrically connected to two USB con-
trollers. The handling of this is totally automatic, but can be noticed since USB 1.x and USB 2.0 devices plugged in to the same connector
appear to connect to different USB busses.
SEE ALSO
ohci(4), uhci(4), usb(4), xhci(4)
HISTORY
The ehci device driver first appeared in FreeBSD 5.1.
LOADER TUNABLES
When the kernel has been compiled with options USB_DEBUG, some tunables become available that affect the behavior of ehci. These tunables
can be set at the loader(8) prompt before booting the kernel or stored in loader.conf(5).
hw.usb.ehci.lostintrbug
This tunable enables the lost interrupt quirk. The default value is 0 (off).
hw.usb.ehci.iaadbug
This tunable enables the EHCI doorbell quirk. The default value is 0 (off).
hw.usb.ehci.no_hs
This tunable disables USB devices to attach like HIGH-speed ones and will force all attached devices to attach to the FULL- or LOW-
speed companion controller. The default value is 0 (off).
