Need to physically separate them now. Then can focus on erasing &
flashing ourselves.
Added some speed checks to bnrom.lua script that I was testing usb code
with. Was able to verify read/write speeds were no affected by changes
in this commit. Did some testing against older firmware v2.2 though
there does seem to have been a slight slow down on write speeds.
Although, perhaps that's because of the nrom flash verifications that
are also included in this build (but not commited)..?
