You mean we can junk the BLIST_INQUIRY flags?  Does the 58 byte inquiry
serve any purpose then (i.e. do you have a device that lies about its
inquiry length but can return 58 bytes?).  The 58 bytes is useful
because SPI fields lie in the 57th byte (information for the higher
ultra speeds), but on the other hand those bits are only defined for a
parallel bus.

If I junk the flags, we'll send a 36 byte inquiry and then one sized
from the inquiry return (unless we have to do an intermediate 58 byte
one) and let you filter them.  Does that sound OK?
