RE: flash drive timing out, can't boot vmlinuz/initrd (coreboot payload)

[Melki Christian (consultant)]

I think you should plug a USB snooper and look at the flow.
This is initial stuff, so it shouldn't be that much data to look at.

Also, dump the device descriptors using linux (lsusb) for example.
It should help with quirk-searching.
