how to disable kernel module without being able to boot?
TL;DR: On Ubuntu 14.04, how do I disable a kernel module that is built into the kernel (blacklisting not possible) when I am unable to boot?
I am trying to boot an Ubuntu 14.04 installation from a USB stick.
(means: I installed Ubuntu FROM a USB stick TO a different USB stick and am now trying to boot from it)
It works on my old USB 2.0 stick. On my new SanDisk Ultra USB 3.0 32GB stick the installation completes just fine, but I am unable to boot.

Of course I have typed the message into Google, but I don't know how to apply the likely solution. Basically: turn off module ehci_hcd. How do I do that if I can't boot and if blacklisting doesn't work, because the module is built into the kernel? I have tried blacklist.conf and grub config file.
I would follow this ^ but my /sys/ folder is empty when I plug my USB stick into a computer to access its files (assuming this is normal?).
The error occurs on my Xeon E3-1230v3 desktop computer and on my old Atom N270 netbook, so I am guessing either the USB stick is broken or it is Ubuntu's fault. (likely Ubuntu from the amount of forum posts hinting to disable ehci_hcd)
Any help would be greatly appreciated.
