Haven't you by any chance rebuilt your kernel with speedtch and
class_firmware built in, and left the old speedtch hanging around?

Please make sure that they are built as modules and that the installed
kernel and modules (and initrd if you use it) are in a consistent state.

A side note: the triple "no stage 1 firmware" message seems to be due to
speedtch trying (and failing) to bind in turn to all three interfaces.
I guess it should better refuse to bind to anything but the interface 0
early in it's probe, and then explicitly claim the interfaces it needs.
