Hi Alex,

Sorry for not getting back to you sooner.

I recently purchased an Asrock E350M1/USB3 motherboard and some flash
chips.  So, I'll give your patch a spin this weekend.

Basically, I'd like to see if there is some way this can be
auto-detected at runtime instead of using a compile time setting.
