Booting livecd written to usb drive doesn't see it for installation source

I created a bootable usb drive using livecd-iso-to-disk. After booting it, I get to the installation source selection. I choose hard disk and it gives me a list. But the usb drive I'm booting from is not on that list. On F9 I could press F2 to get to the extra drive selection and then go back to the list, and the usb drive partition would be now listed. (I think that was the method, I had to fiddle around a lot to get it to show up.) On F10beta, the only way I can get it to show up is to pull the drive out and plug it in again. I wasn't able to test if I could actually install from it, but it did show up in the list.
The partition on the bootable usb drive where I keep the installation DVD image shows up in the list of hard drives to install from.
On tty4 you should see the kernel messages. Prior to removing and reinserting the USB disk, is there any indication the kernel was able to detect the device and scan its partition table? If they've scrolled off, you can use dmesg from the shell on tty2. I see this problem fairly often when testing the updates mechanism with USB disks.
I see the problem. I'm too quick. :-)
There is a delay before the usb drive is scanned and I select the hard drive option before it is scanned. So I don't know what you could do about that other than maybe a rescan option in the menu.
Unfortunately, there's really nothing we can do here as we get no notice from the underlying hardware probing layers that devices are ready or not. We could always put in random sleeps in the hopes we'll wait long enough and things will be ready to go, but ugh.
