Forgive my ignorance, and TBH the amount of material available
for the USB newbie is bewildering, but is it not possible to bit-
bang USB ? That's not to say I would do that if another option is
available, such as alternate memory, but it seems most protocols
have both hardware and software (ie bit-banging) solutions. Is
that not the case for USB ?
