I guess, you have to specify the model (likely 2232H in your case). See
the manpage `man ./flashrom.8`. If that doesn't work, you can check the
output of `lsusb` if your board uses a special USB device id that we
might have to add to flashrom.

Unlikely.

Compiling from source on Chromebook:GalliumOS - can't get libusb?

Woooo looks like that did it! I don't have a flash device connected yet but
Flashrom certainly found the 2232.

Thanks for the help, I hope I can contribute definitions for the flash
chips I use (Cypress/Spansion 128/256Mbit) if I find they aren't in the
database already.
