[Fedora-livecd-list] custom spin kernel panic

Hello,

I need some help. I am trying to create a custom fedora 9 spin, but when I burn the spin
to cd, I keep getting kernel panic when I try to boot from the spin.

The message I am getting before the panic is:

unable to enumerate devices on usb port 2.

Steps I have taken:
1. Install fedora 9 (sulphur) on a fresh system.
2. checked out spin-kickstart from the git repository.
3. Ran livecd-creator using just the fedora-live-base.ks and burned it to a cd.
4. Booted from this cd (got to the login prompt and was able to login as fedora).
5. Created my own kickstart file as follows:

%include fedora-live-base.ks

%packages
brltty
%end

At present I have no need for a custom %post section so I didn't put one in.

I ran livecd-creator using my kickstart file and the iso was created (about 3mb larger
than the base iso image).
I burned thsi image to disk and rebooted.
After the isolinux delay, I get the keernel panic and message about enumerating the usb
devices.

As a blind user, I want to have an accessible livecd to use to help rescue my system if
necessary, so I am very interested in getting this to work, and after a little tweaking, I
am willing to add it to the repository for others to use.

Any suggestions on how to fix the kernel panic would be appreciated.

BTW: I have a 4-port kvm switch connected to the usb port of the computer and a 7-port usb
hub going into the switch. I have the keyboard and braille display going into the hub.
