Hi Nico,

Thanks for the details. I somehow managed to build filo by defining CONFIG_USB in build/config.h However having problems at run time. Logs are below. Can you please suggest last known commit where USB was working good? Currently it seems to be messed up. I have to boot Linux from USB using coreboot without Seabios and I am facing problem with both FILO and GRUB2.

Logs for the problem I am getting repeatedly at run time
change on port 1
fullspeed device
first get_descriptor(DT_DEV) failed
set_address failed

The prefix for libpayload's configurations options changed to CONFIG_LP_,
lately. The last commit for FILO (60d45fc) tried to fix it, but seems to
have missed some options. So CONFIG_USB is CONFIG_LP_USB, now.

Also, if you get current FILO to compile with USB support, depending on your
platform, it might not work as expected. I hit some strange regressions with
older hardware this week, that I'm still investigating.
